Question type

Principle (Comparative)

The one idea it tests

A principle under both passages is a general rule each author leans on, usually unstated, that makes both lines of reasoning work.

The basic logic

Ask why each author cares. What would be bad if things stay as they are? If both passages treat being left out of an official category as a harm, the shared principle is about that harm. Test each choice: would both authors need it?

Tiny words that decide it

“both”
“underlie”
“can be”

Playground logic

Nadia worries the ants miss the snack budget because they are left off the list; Lulu worries the unsigned form costs them crumbs. Both lean on one rule: being left off the official list by whoever is in charge can hurt you.

Step 2 · The kid passage

This question belongs to Passage 3 (Questions 16–21). Read its kid passage and structure guide first: Who Counts as a Class Pet? →

Step 3 · Try the model question

Which rule do both Nadia and Lulu seem to rely on?

Step 5 · Work the real question

Open PrepTest 127, Section 4, Question 21 in your official copy from LSAC (for example in LawHub) and read it there.

Your answer

How to apply it

Open Question 21 in your official copy and answer it first.

Find, in each passage, the spot where the author implies something bad happens to the group. Say in general words what that bad thing comes from. Then test each choice: does passage A need it, and does passage B? Drop rules that only one author uses, that go far beyond either, or that come from nowhere.
