Question type

Main Point

The one idea it tests

The main point is the authors' big claim, usually a puzzle plus their answer.

The basic logic

Find the puzzle the authors raise and the solution they defend. The right choice covers both how it started and why it lasted.

Tiny words that decide it

“however”
“we propose”
“less clear”

Playground logic

The muddy field and new sets explain why the switch started. But Nadia and Owen's real point is that something else, momentum from earlier switchers, explains why it kept going.

Your answer

How to apply it

Open Question 7 in your official copy and answer it first.

Find where the authors switch from reporting to proposing. State their claim in one line: what began it, and what kept it going. Pick the choice that covers both parts. Reject choices that just restate background facts, list only the starting triggers, or describe one supporting detail.
