Question type
Main Point
The one idea it tests
The right answer captures the whole passage arc: the puzzle, the new evidence, and its limited but real payoff.
The basic logic
Find the author's top bun near the end. The answer must include the new evidence AND its partial reach. Choices that only restate the puzzle, or that overstate or reverse the payoff, miss the point.
Tiny words that decide it
  • “but”
  • “still”
  • “only”
  • “even so”

Playground logic

In the kid passage, the burger's top bun is that Lulu's evidence lets the kindergartners explain part, not all, of the missing water, and that part still matters.

Step 2 · The kid passage

This question belongs to Passage 3 (Questions 13–19). Read its kid passage and structure guide first: The Case of the Extra Water →

Your answer

How to apply it

Open Question 13 in your official copy and answer it first.

Read the last paragraph twice; that is where the author's verdict lives. State the point in your own words: puzzle, new evidence, partial but meaningful answer. Then pick the choice that keeps all three pieces. Cross off any choice that only restates the puzzle, any that turns 'part' into 'all' or 'none', and any that blows up a single detail.
