Main Idea flashcards

The topic is the subject in a word or phrase (night shifts). The main idea is a full statement of what the passage says about that subject, answering 'so what?'

Check each choice against every sentence. If a sentence would be left out, the choice is too narrow; if it brings in things no sentence mentions, it is too broad.

Too broad: describes a bigger subject than the passage covers (fire safety everywhere). Too narrow: repeats one detail, often accurately, and ignores the rest. The answer matches the passage's size.

A choice that is true in real life but not stated or supported by the passage. The question asks what this passage supports, not what is generally correct.

The answer must keep the passage's strength. 'Can reduce rust' does not mean prevents all rust; choices with always, never, all or only, or that turn 'linked to' into 'causes', usually go too far.

Ask what conclusion all the details share, then pick the choice that states it without exaggerating. Cracked planks, missing railings and warning signs imply the pier is unsafe.

The main idea is what the passage says (the new method shortened learning time). The purpose is why it was written: to inform, explain or persuade. Read which one the question asks for.

When stuck between two choices, prefer the one that needs fewer unstated facts or steps to be true. The best answer can be defended using the passage alone.
