Synonyms: Core Method Lesson Test

Answer: D

Correct answer: hardworking. Diligent means showing steady, careful effort. Hardworking can stand in for it and say the same thing, while intelligent, wealthy and punctual are related traits or results.

• A: Being on time is a separate good habit; diligent is about steady effort, not timing.
• B: Hard work may lead to money, but wealth is a possible result, not what diligent means.
• C: Diligent people are often assumed to be smart, but being clever is an association, not the meaning of diligent.
• D (correct): Diligent describes someone who works steadily and carefully, so hardworking says the same thing.

Answer: B

Correct answer: shy. Timid means easily frightened or lacking confidence. Shy matches that meaning; bold is the opposite, and silent and tiny are an association and a look-alike.

• A: Bold is the opposite of timid; it feels connected only because it is on the same topic.
• B (correct): Timid describes someone lacking courage or confidence, which matches shy.
• C: A timid person may stay quiet, but silence is an association, not the meaning.
• D: Timid and tiny look alike at the start, but size has nothing to do with being fearful.

Answer: A

Correct answer: communicate. CONVEY follows please and takes an object, so it is a verb meaning pass along or express. Only communicate is a verb with that meaning: please communicate our thanks.

• A (correct): Convey here is a verb meaning to pass along or express, and communicate fits that role and sense.
• B: To keep something to oneself is to hold it back, the opposite of passing the thanks along.
• C: Grateful is an adjective tied to the topic of thanks, but it cannot replace a verb in the sentence.
• D: Message is a noun for what is sent, not the action of sending it.

Answer: B

Correct answer: plentiful. Abundant means more than enough, existing in large quantity. Plentiful matches that meaning, while rare is its opposite.

• A: Rare means hard to find, the opposite of abundant.
• B (correct): Abundant means present in large amounts, which is exactly what plentiful says.
• C: Value is a separate idea; plentiful things are often less valuable, not more.
• D: Growing describes an increase over time; something can be abundant without growing.

Answer: D

Correct answer: empty. Vacant means unoccupied or empty. Rented, quiet and dusty describe things that may go along with a place but do not mean empty.

• A: An unused building might gather dust, but that is a side effect, not what vacant means.
• B: An empty room may be quiet, but quiet is an association rather than the meaning.
• C: Rented describes a place someone has taken, which suggests it is occupied rather than vacant.
• D (correct): Vacant means not occupied or containing nothing, the same as empty.

Answer: C

Correct answer: outdated. Predict first: obsolete means out of date, replaced by something newer. Outdated matches that prediction, while broken, expensive and complicated are possible traits that the word does not state.

• A: Complexity is a different property; a simple system can also be obsolete.
• B: An old system may break down, but obsolete systems can still work; broken adds a condition not in the word.
• C (correct): Obsolete means no longer current or in general use, which outdated captures.
• D: Cost is unrelated to whether something is out of date.

Answer: C

Correct answer: overjoyed. Elated is at the top of the happiness scale. Pleased is on the same scale but much weaker, so overjoyed is the best match in both meaning and intensity.

• A: Calm describes a peaceful state, not intense happiness.
• B: Relief is a different emotion, the easing of worry, not great joy.
• C (correct): Elated means extremely happy, and overjoyed matches both the feeling and its strength.
• D: Pleased names the right feeling but is far too mild for elated.

Answer: D

Correct answer: home. Dwelling is a broad word for a place where someone lives. Home has the same scope, while cabin and mansion are narrower types and neighborhood is wider.

• A: A neighborhood is an area containing many homes, so it is too broad.
• B: A mansion is a large, specific type of house, adding size and wealth not in dwelling.
• C: A cabin is one specific kind of dwelling, so it is too narrow.
• D (correct): A dwelling is any place where people live, which matches the general word home.

Answer: B

Correct answer: reach. Attain implies completion: the goal was reached. Reach shares that outcome, while seek and attempt describe only the effort; few climbers attempt the summit would change the claim.

• A: Seek means to look for or try to get, which describes the effort but not the success.
• B (correct): Attain means to succeed in getting to or gaining something, and reach also says the goal was arrived at.
• C: Attempt is only the try; attain requires that the goal actually be reached.
• D: Avoid means keep away from, the opposite of getting to the summit.

Answer: C

Correct answer: determined. Persistent denotes keeping on despite obstacles. Determined and stubborn both share that core, but the sentence praises the volunteer, so the neutral-to-positive determined fits the tone better than the critical stubborn.

• A: Careless means not paying attention, which has nothing to do with continuing an effort.
• B: Stubborn shares the idea of not giving up but adds a negative sense of refusing to change, which does not fit this praising sentence.
• C (correct): Persistent means continuing firmly despite difficulty, and determined matches that meaning with a fitting positive tone.
• D: Impatient describes being unwilling to wait, which is a different idea from steady effort.

Answer: B

Correct answer: draw out. Elicit is a verb meaning to draw out a response or information. Illicit sounds similar but means illegal, so unlawful is a sound-alike trap.

• A: Conceal means hide, the opposite of bringing the truth out.
• B (correct): Elicit means to bring out a response or information, which is what draw out means.
• C: Unlawful is the meaning of illicit, a different word that only sounds like elicit.
• D: Asking questions is the method used, but elicit names the result of getting the truth out.

Answer: C

Correct answer: bandage. Dress has several senses. Substituting each candidate shows that only bandage keeps the sentence's meaning: the medic stopped to bandage the soldier's wound.

• A: Decorate matches another sense of dress, as in dressing a window, but not this sentence.
• B: Clothe is the common sense of dress, but it does not fit a wound.
• C (correct): With a wound, dress means to clean and cover it, which is what bandage means.
• D: A medic may examine a wound first, but examining is a different action from dressing it.

Answer: C

Correct answer: watchful. Swap each choice into the sentence. The sentry stayed watchful keeps the meaning of staying alert; drowsy reverses it, and heavily armed and posted add different facts.

• A: Drowsy means sleepy, the opposite of alert.
• B: A sentry may carry weapons, but heavily armed is an association, not the meaning.
• C (correct): Vigilant means alert and on the lookout, so the sentry stayed watchful keeps the meaning.
• D: Posted states where the sentry was placed, which is a different fact.

Answer: A

Correct answer: kind. The part bene- suggests well or good, pointing toward a positive meaning. Benevolent means wishing good to others, so kind is the closest match.

• A (correct): Benevolent means well-meaning and generous toward others, which kind captures.
• B: Benevolent can describe a ruler, but power is a separate idea from good will.
• C: A benevolent person may give money, but having wealth is not the meaning.
• D: Cruel is the opposite of benevolent.

Answer: A

Correct answer: agreed on by all. Unanimous means with the agreement of everyone involved. A majority is a narrower claim, so agreed on by all is the only exact match.

• A (correct): Unanimous means every member agrees, which agreed on by all states directly.
• B: Most falls short of unanimous; a majority vote still leaves some members opposed.
• C: Speed is a separate fact; a unanimous decision can take a long time.
• D: Popular describes public approval, not agreement among every member.

Answer: D

Correct answer: accompany. Escort follows will, so it is a verb meaning go with someone as a guide or guard. Accompany is a verb with that meaning; bodyguard is a noun and fails the grammar test.

• A: Release means let go, which is unrelated to walking with someone.
• B: Bodyguard is a noun naming a person, so it does not fit the verb role in the sentence.
• C: Welcoming is greeting someone on arrival, not going along with them.
• D (correct): Escort here is a verb meaning to go along with someone, which accompany matches.

Answer: B

Correct answer: frank. With no sentence given, use the standard meaning: candid means open and truthful. Frank matches; sugary is a spelling trap from candied, and secretive is an opposite.

• A: Polite concerns good manners; a candid remark may or may not be polite.
• B (correct): Candid means honest and direct in what one says, the same as frank.
• C: Sugary comes from confusing candid with candied, a look-alike word.
• D: Secretive is the opposite of open and honest.

Answer: B

Correct answer: extremely thirsty. Parched means very dry and, for a person, very thirsty. Slightly thirsty misses the intensity, while exhausted and sunburned are ideas suggested by the setting rather than the word.

• A: Slightly thirsty has the right idea but is far too weak for parched.
• B (correct): Parched describes a severe need for water, matching both the idea and the strength.
• C: Heat suggests sunburn, but that is an association with the setting, not the meaning.
• D: Tiredness goes along with a long climb, but parched is about thirst, not fatigue.

Answer: D

Correct answer: firm. Resolute denotes being determined and unwavering. Obstinate shares part of that denotation but sounds negative, while the sentence praises the general, so firm is the best fit in both meaning and tone.

• A: Obstinate shares the idea of not yielding but carries a critical tone that clashes with admired.
• B: Reckless means careless of danger, which is a different trait from steady determination.
• C: Uncertain is the opposite of resolute.
• D (correct): Resolute means firmly determined, and firm keeps the admiring meaning of the sentence.

Answer: A

Correct answer: became expert at. Mastered implies the goal was reached: full skill. Practiced and studied describe only the work toward it, and finally in the sentence signals completion, so became expert at is the match.

• A (correct): Mastered means gained full skill in something, so became expert at states the completed result.
• B: Practicing is the effort leading toward mastery; it does not say full skill was reached.
• C: Teaching may follow mastery, but it is a different action from gaining the skill.
• D: Studying is an attempt to learn, not the successful outcome that mastered implies.

Answer: A

Correct answer: sensible. Prudent means wise and careful in practical matters. A chain like prudent, cautious, timid drifts away step by step, so compare each choice directly with prudent; only sensible keeps the meaning.

• A (correct): Prudent means showing good judgment and care about the future, which sensible matches directly.
• B: Hasty means acting too quickly without thought, the opposite of prudent.
• C: Skill at driving is a different quality from the good judgment that prudent names.
• D: Timid comes from a chain such as prudent to cautious to timid; the last link adds fear, which prudent does not mean.

Answer: D

Correct answer: weaken. Enervate means to sap strength. It resembles energize in spelling, but the sentence about a draining heat wave confirms the meaning weaken.

• A: Energize looks like enervate but means nearly the opposite; similar spelling is a trap.
• B: Organize is unrelated to the effect of heat on workers.
• C: A heat wave could make people irritable, but enervate concerns loss of strength, not emotion.
• D (correct): Enervate means to drain of strength or energy, which weaken matches and which fits the effect of heat.

Answer: C

Correct answer: believable. Plausible means appearing reasonable or probably true. Proven adds certainty the word does not contain, so believable is the closest meaning without overstating.

• A: False is close to the opposite of how plausible presents the explanation.
• B: Proven overstates plausible; a plausible story seems likely but has not been confirmed.
• C (correct): Plausible means seeming reasonable or likely to be true, which believable matches.
• D: A plausible explanation may or may not be detailed; that adds a property not in the word.

Answer: A

Correct answer: brief. Terse means short and to the point, sometimes to the point of seeming abrupt. Its core is few words, so brief matches; angry adds a feeling the word does not state, and lengthy is the opposite.

• A (correct): Terse means using few words, so a brief reply keeps the core meaning.
• B: Lengthy is the opposite of terse.
• C: Terse replies are short but can still be perfectly clear.
• D: A terse reply can seem abrupt, but anger is an added emotion, not the meaning of the word.

Answer: B

Correct answer: reduce. Predict a plain paraphrase first: curtail means cut back. Reduce matches that meaning and degree, while eliminate goes too far, extend is an opposite, and schedule is only a related idea.

• A: This overstates the word; curtailing overtime cuts it back, while eliminating it would end it completely.
• B (correct): Curtail means to cut back or cut short, so reduce keeps the sentence's meaning: overtime is lowered, not removed.
• C: This points the opposite way, adding hours instead of cutting them.
• D: Planning when overtime happens is a related task, but it says nothing about having less of it.

Answer: C

Correct answer: imprecise. Vague describes something stated without clear detail. Substitute: 'the mechanic gave only an imprecise estimate' keeps the meaning, while hurried and costly add different facts and detailed reverses it.

• A: This is the opposite; a detailed estimate would spell things out clearly.
• B: Cost is a topic that goes with repair estimates, but it does not describe how clear the estimate was.
• C (correct): Vague means not clearly stated or not specific, which is what imprecise says about the estimate.
• D: A rushed answer might also be vague, but hurried describes speed, not lack of clarity.

Answer: D

Correct answer: agree. Concur means to agree or hold the same opinion. 'Both pilots agree on the new flight plan' keeps the sense, while argue is an opposite and meet and compete name different actions.

• A: Competing means trying to beat each other, which does not fit two people sharing the same view of a plan.
• B: Arguing is the opposite of concurring; it means the pilots disagree.
• C: Meeting may come before an agreement, but getting together is not the same as sharing the same opinion.
• D (correct): Concur means to be of the same opinion, so agree is the closest match.

Answer: B

Correct answer: honor deeply. Predict first: people at a memorial treat a memory with great respect. Honor deeply matches that meaning, while revise is a look-alike and forget is an opposite.

• A: Revise only looks like revere; it means to change or correct a text, a sound-alike trap.
• B (correct): To revere is to regard with deep respect and admiration, which fits a memorial ceremony.
• C: Awe can include some fear, but revere centers on respect, not being afraid.
• D: This reverses the attitude; people who revere a memory keep it alive.

Answer: C

Correct answer: tactful. Do not let spelling decide: discreet (careful in what one says or reveals) is different from discrete (separate, distinct). The sentence's clue 'never discusses them in public' points to careful, tactful behavior.

• A: This is the meaning of the sound-alike word discrete, not discreet.
• B: Outspoken means quick to say what one thinks, which is the opposite of keeping quiet.
• C (correct): Discreet means careful about what one says or reveals, and tactful captures that careful, sensitive judgment.
• D: Someone forgetful might not repeat plans, but the word means failing to remember, not choosing to keep quiet.

Answer: A

Correct answer: assign. Allocate means to distribute something for a particular person or purpose. Substitute assign: 'the supervisor will assign tasks to the crew' keeps the meaning; collect reverses it, and approve and finish are different steps.

• A (correct): Allocate means to give out shares or portions to particular people, so assign fits giving out tasks.
• B: Approving tasks means giving permission for them, a separate decision from handing them out.
• C: Collecting gathers things in, which is roughly the opposite of handing them out.
• D: Completing tasks is what the crew does later; it is not what allocating means.

Answer: A

Correct answer: tiresome. Tedious describes work that is dull and tiring because it drags on. Tiresome keeps that meaning; difficult adds a different condition, careful is only associated, and brief is opposite in spirit.

• A (correct): Tedious means dull and wearying because it is long or repetitive, which tiresome expresses.
• B: A tedious job can be easy; it is boring and repetitive rather than hard to do.
• C: Counting by hand might require care, but careful describes the worker, not the dull nature of the job.
• D: This contradicts the idea of a long, drawn-out task.

Answer: C

Correct answer: change. Modify means to alter something, usually in part. Change matches the core action; improve adds an outcome the word does not promise, replace goes too far, and approve is a different decision.

• A: Approving the design means accepting it, not altering it.
• B: Replacing swaps the design for a new one, which overstates a change to part of it.
• C (correct): Modify means to make some changes to something, so change is the closest match.
• D: Improving names a good result, but a modification may or may not make the design better.

Answer: C

Correct answer: disrespectful. Insolent means boldly rude, as when a recruit talks back to an instructor with open contempt. Eliminate the look-alikes indolent (lazy) and insolvent (bankrupt), then reject outspoken because frankness alone is not rude; disrespectful is the best match.

• A: Lazy is the meaning of indolent, a different word that shares the ending -olent.
• B: Bankrupt matches insolvent, a shape-alike word that differs by one letter.
• C (correct): Insolent describes speech or behavior that is boldly rude and lacking in respect, so disrespectful is the true synonym.
• D: A frank, outspoken person speaks plainly, but that can be polite; it misses the rudeness at the core of insolent.

Answer: D

Correct answer: plentiful. Ample means enough or more than enough. Test it: packed plentiful water fits, and no one running short confirms it; excessive overstates the degree and scarce reverses it.

• A: Excessive means too much, a stronger and negative degree that ample does not carry.
• B: Simple only rhymes with ample; it has nothing to do with quantity.
• C: Scarce means in short supply, the opposite of ample.
• D (correct): Ample means more than enough, and the sentence confirms that no one ran short.

Answer: A

Correct answer: danger. A hazard is something that could cause harm, such as a wet floor or a loose wire. Danger matches; accident is a possible result, warning is an associated sign, and safety is the opposite.

• A (correct): A hazard is a source of possible harm, which is what danger means.
• B: An accident is something that may result from a hazard, not the hazard itself.
• C: A warning tells people about a hazard; it is not the danger.
• D: Safety is the opposite of a hazard.

Answer: A

Correct answer: weak. Feeble means weak, whether in body (a feeble grip) or in effect (a feeble attempt). Elderly is only a related idea that often comes to mind, not a synonym.

• A (correct): Feeble means lacking strength or force, as in a feeble voice or a feeble excuse.
• B: Older people are sometimes feeble, but age is an association, not the meaning; a sick child can also be feeble.
• C: Shy describes timid social behavior, not a lack of strength.
• D: Cheap describes low cost or low quality, not physical weakness.

Answer: B

Correct answer: lessen. Mitigate means to make something less harsh or severe. The phrase 'until help arrived' shows the pain was only eased, so lessen fits; cure claims a complete result, diagnose is a related medical step, and increase is the opposite.

• A: A cure ends the problem completely, which overstates mitigate; the pain is eased, not removed.
• B (correct): Mitigate means to make something less severe, so lessen is the best match.
• C: Diagnosing identifies the cause of a problem; it does not reduce the pain.
• D: This is the opposite of making pain less severe.

Answer: B

Correct answer: scolded. Admonish means to warn or reprimand someone firmly in words. Scolded matches that action; punished adds a penalty the word does not include, praised is the opposite, and dismissed is an unrelated action.

• A: Punishing imposes a penalty; admonishing is a verbal warning or scolding, so this overstates the word.
• B (correct): Admonish means to warn or criticize someone firmly, which scolded captures.
• C: This is the opposite of a firm criticism.
• D: Sending the soldiers away is a different action from speaking sharply to them.

Answer: A

Correct answer: calm. Pacify means to soothe or quiet someone who is angry or upset. Calm fits the sentence; provoke is the opposite, and question and ignore name different responses.

• A (correct): Pacify means to soothe someone who is upset, so calm is the closest match.
• B: Provoking someone stirs up anger, which is the opposite of pacifying.
• C: Asking questions might happen during the exchange, but it does not mean soothing.
• D: Ignoring the passenger would not be an attempt to soothe him.

Answer: C

Correct answer: joint. A concerted effort is one carried out jointly by several people or groups. The clue 'from three towns' supports joint; musical is a spelling association, and desperate and sincere describe feelings rather than cooperation.

• A: This is an association with the look-alike word concert, not the meaning of concerted.
• B: The effort might have been urgent, but desperate describes feeling hopeless, not working together.
• C (correct): Concerted means planned or carried out together, which matches joint.
• D: Sincerity describes honesty of feeling, not people acting together.

Answer: C

Correct answer: assemble. Compile means to collect material from different sources and put it together. Assemble fits 'into one binder'; write, review and mail are related office tasks with different meanings.

• A: Reading the reports closely and critically is a different task from collecting them together.
• B: Sending the reports is an action that might follow, not the act of gathering them.
• C (correct): Compile means to gather items from several sources into one collection, which assemble expresses.
• D: Compiling uses material others have already written; it does not mean writing out the text.

Answer: A

Correct answer: stiff. Rigid means firm and not able to bend. Stiff matches; flexible is the opposite, and heavy and broken describe other qualities.

• A (correct): Rigid means unable to bend, which is what stiff means.
• B: This is the opposite of rigid.
• C: Rigid objects may be heavy, but weight is a separate property from stiffness.
• D: A broken item is damaged, which has nothing to do with being unable to bend.

Answer: D

Correct answer: inactive. Dormant means inactive for now but capable of becoming active again. The clue that scientists still monitor it rules out extinct, which means permanently inactive; erupting is the opposite and hidden is unrelated.

• A: Extinct means no longer able to erupt at all, which overstates dormant; the monitoring shows it could become active again.
• B: This is the opposite; an erupting volcano is active right now.
• C: Dormant does not mean out of sight; the volcano is simply quiet.
• D (correct): Dormant means temporarily quiet or asleep, which inactive captures.

Answer: D

Correct answer: free of errors. Accurate means correct, matching the facts. Free of errors keeps that meaning; honest concerns intent, full of details concerns amount of information, and lengthy concerns size.

• A: The length of an account says nothing about whether its facts are right.
• B: An honest witness can still be mistaken; honest describes intent, while accurate describes correctness.
• C: An account can be full of details and still contain errors; detail is not the same as correctness.
• D (correct): Accurate means correct and exact, which is what free of errors says.

Answer: B

Correct answer: hold back. Hinder means to create difficulties that slow or delay something. Hold back matches that degree; stop completely is too strong, assist is the opposite, and follow is unrelated.

• A: Stop completely overstates the word; hindering makes efforts harder or slower without necessarily ending them.
• B (correct): Hinder means to get in the way of something and slow it down, which hold back expresses.
• C: This is the opposite of hindering.
• D: Following comes after something; it does not mean getting in its way.

Answer: C

Correct answer: worsen. Exacerbate means to make an existing problem worse. The word 'only' and the ongoing flooding show the problem is already present, so worsen fits; cause would mean starting it, relieve is the opposite, and delay changes timing.

• A: The flooding already exists, so the rain cannot cause it; exacerbate means making an existing problem worse.
• B: Delaying the flooding would push it later, which is a different idea.
• C (correct): Exacerbate means to make a bad situation more severe, so worsen is the best match.
• D: This is the opposite; relieving would make the flooding less severe.

Answer: C

Correct answer: polite. Courteous means well-mannered and respectful toward others. Polite matches; rude is the opposite, and formal and cheerful describe different qualities.

• A: This is the opposite of courteous.
• B: A formal person follows strict rules of dress or ceremony, which is not the same as being kind and respectful.
• C (correct): Courteous means showing good manners and respect, which polite expresses.
• D: A cheerful person is in a good mood, which differs from having good manners.

Answer: B

Correct answer: required. Compulsory means required by a rule or law. Required matches exactly; recommended is too weak, voluntary is the opposite, and expensive is unrelated.

• A: This is the opposite; voluntary means left to a person's choice.
• B (correct): Compulsory means something must be done, which is what required means.
• C: A recommendation is advice, which is weaker than a rule that must be followed.
• D: Cost is unrelated to whether wearing a hard hat must be done.

Answer: A

Correct answer: angered by unfair treatment. Indignant describes anger provoked by unfairness. The sentence supports this, since the sailor is blamed for a mistake he did not make; lacking money and native to an area belong to the look-alikes indigent and indigenous, and shame is a feeling the context rules out.

• A (correct): Indignant means angry because something seems unjust, which fits being blamed for someone else's mistake.
• B: This defines indigent, a sound-alike word; nothing in the sentence concerns money.
• C: This defines indigenous, another look-alike that starts with indig-.
• D: He did not make the error, and indignant expresses anger at injustice, not shame.

Answer: A

Correct answer: keep. Retain means to keep possession of something. Keep fits 'until the trip expenses are approved'; return is the opposite, and collect and copy are related but different actions.

• A (correct): Retain means to continue to have or hold on to something, so keep is the closest match.
• B: Handing the receipts back is the opposite of holding on to them.
• C: Collecting means gathering things up, not continuing to hold what one already has.
• D: Making copies is a related office task, but it does not mean holding on to the originals.

Answer: B

Correct answer: unstable. Volatile describes something liable to change quickly and unpredictably, often for the worse. Unstable keeps that meaning; violent claims the change has already happened, hopeless adds an outcome, and secret is unrelated.

• A: Violent states that fighting is happening, which overstates volatile; the word describes a situation that could change suddenly.
• B (correct): Volatile means likely to change suddenly or explosively, which unstable captures.
• C: Hopeless means without any chance of improvement, a much stronger and different claim.
• D: Secrecy has nothing to do with how likely a situation is to change.

Answer: D

Correct answer: relevant. Pertinent means relating directly to the subject being discussed. Relevant fits 'pertinent to the cooling problem'; rude comes from confusing it with impertinent, accurate is a different quality, and lengthy is unrelated.

• A: This is the meaning of the look-alike word impertinent, not pertinent.
• B: The length of the remarks is not what pertinent describes.
• C: Remarks can be correct but off the topic; pertinent is about relevance, not correctness.
• D (correct): Pertinent means directly connected to the matter at hand, which relevant expresses.

Answer: A

Correct answer: shortage. Dearth means a scarcity or lack. The result 'slowed repairs' supports shortage; death is a look-alike word, surplus is the opposite, and training is only associated with mechanics.

• A (correct): Dearth means a lack or scarcity of something, which shortage expresses.
• B: This is a sound-alike trap; dearth has nothing to do with dying.
• C: This is the opposite; a surplus of mechanics would not slow repairs.
• D: Training is related to whether mechanics are qualified, but it does not mean a lack of them.

Answer: D

Correct answer: piece. A fragment is a small part broken or separated from a whole, such as a fragment of glass. Piece matches; whole is the opposite, and crack and copy describe different things.

• A: This is the opposite; a fragment is only part of something.
• B: A crack is a break line in an object, not a separated piece of it.
• C: A copy is a duplicate of something, not a broken-off part.
• D (correct): A fragment is a small part broken off from something larger, which is a piece.

Answer: B

Correct answer: genuine. Authentic means genuine, truly what it claims to be. Experts confirming the logbook points to genuine; ancient and detailed are associated qualities, and official means approved by an authority, not real.

• A: An official document is issued by an authority, which is different from being real rather than fake.
• B (correct): Authentic means real, not copied or faked, which genuine expresses.
• C: Age is associated with old records, but a document can be old and still be a fake.
• D: The amount of detail does not tell whether the logbook is real.

Answer: C

Correct answer: supported. As a verb, advocate means to argue for or recommend something. Supported fits; opposed is the opposite, invented is a different act, and explained lacks the sense of favoring the plan.

• A: Explaining a route describes it, but does not show the speaker was arguing in its favor.
• B: This is the opposite of speaking in favor of the route.
• C (correct): Advocate as a verb means to speak publicly in favor of something, so supported is the best match.
• D: Creating the route is a different act; a person can advocate a plan someone else designed.

Answer: B

• C: Travel is the journey itself; depart is only the act of setting out.

• C: This is the opposite of humid.
• D (correct): Humid means containing a lot of moisture, especially in the air, which matches moist.

Answer: A

• B: This is the opposite of prohibit.
• C: Discouraging only tries to talk someone out of something, which is weaker than a ban.

• B: Illness can make someone frail, but sick names a cause, not the quality of being weak.
• C: Small size does not mean weakness.
• D (correct): Frail means physically weak or delicate, which matches weak.

Answer: D

Correct answer: sufficient. Adequate means enough or satisfactory for a purpose. Sufficient matches in meaning and degree; excellent and extra overstate it, and lacking is the opposite.

• A: Excellent is far stronger than adequate, which means only good enough.
• B: This is the opposite; lacking means not enough.
• C: Extra means more than is needed, which overstates adequate.
• D (correct): Adequate means enough for the need, which is what sufficient means.
