Step 1 · Pre-Question Guidance · read this first

Question type

Comparative

The one idea it tests

A 'one but not the other' question is a simple detail hunt across both texts.

The basic logic

For each choice, scan passage B for it, then scan passage A. The answer must show up in B and be absent from A. Watch for words that appear in both, or only in A.

Tiny words that decide it

“but not”
“mentioned”

Playground logic

A referee appears only in Part B. Treats appear only in Part A. Class rules appear in both.

Step 2 · The kid passage

This question belongs to Passage 4 (Questions 20–27). Read its kid passage and structure guide first: Perfect Fair versus Playground Fair →

Step 3 · Try the model question

Which is mentioned in Part B but not in Part A?

Step 5 · Work the real question

Open PrepTest 128, 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.

Check each choice against both passages, B first. Note whether each item appears in B, in A, or in both. Keep only the one in B and absent from A. Be careful with ideas mentioned in both using different words.
