Playground logic
Nadia says a class pet monitor's job includes keeping the hamster happy (patty), so the monitor must keep the wheel squeak-free (top bun). The secret sauce is that a quiet wheel helps keep the hamster happy. Add that bridge and the burger holds together.
Step 2 · The kid story
Nadia and the Squeaky Wheel
Nadia was class pet monitor this week. Ms. Rivera had written the job on the board: 'Part of the monitor's job is to keep Peanut the hamster happy.' Nadia turned to Owen. 'So the monitor has to oil Peanut's wheel every day.' Owen squinted. 'Wait. The board says happy. It doesn't say anything about oil.' Marcus nodded. 'Detective verdict: total jump.' Priya held up her juice box. 'It is a jump, but a fixable one. What would connect them?' Lulu flipped her clipboard. 'If oiling the wheel helps keep Peanut happy, then a job about happiness includes the oil.' Nadia grinned. 'Peanut hates the squeak. He stops running when it squeaks.' 'There you go,' Priya said. 'That is the bridge between the job and the oil can.' Peanut ran, silently, all afternoon.
Step 3 · Try the model question
Nadia: One part of the class pet monitor's job is to keep Peanut the hamster happy. So the monitor has a duty to oil Peanut's exercise wheel every day.
Which statement, if true, gives the most support to Nadia's argument?
Step 4 · The courtroom tale
The Case of the Lighthouse Paint
Mr. Whitfield faced the jury. 'One of the lighthouse keeper's duties is to keep ships safe. Therefore the keeper must repaint the tower bright white every spring.' The keeper's lawyer, Ms. Tran, objected. 'Your Honor, safety is one thing and paint is another. Where is the link?' Mr. Whitfield nodded slowly, then called a sea captain to the stand. 'Captain, does a bright white tower help you see the lighthouse by day?' 'Absolutely. A faded tower vanishes against the fog.' Mr. Whitfield turned back. 'There is the bridge, Your Honor. Fresh paint keeps ships safe.' The judge wrote one word: 'Connected.'
Step 5 · Work the real question
Open PrepTest 134, Section 2, Question 4 in your official copy from LSAC (for example in LawHub) and read it there.
Your answer
How to apply it
Find the premise and the conclusion and circle the key term in each. Notice they talk about different things: a role or purpose in the premise, a specific action in the conclusion. State the missing bridge in your own words: doing the action serves the purpose. Then hunt for the choice that supplies that link. Reject choices that discuss only one side of the gap, mention other duties or people, or push the purpose and the action apart.
