Most Strongly Supported

The one idea it tests

When one specific signal stops a reaction and similar signals do not, the strongest inference is a learned link between that signal and relief.

The basic logic

Stay inside the lunchbox. The facts show a reaction that stops for one source and not for others, in a group defined by who usually takes care of them. Pick the modest answer that explains the pattern without adding words like best, only, or first.

Tiny words that decide it

“merely”
“while”
“do not”
“temporary”

Playground logic

Biscuit whines at the door when he needs to go out, and he stops for a moment only when he hears Lulu's keys, because Lulu is the one who always walks him. The lunchbox supports a modest inference: Biscuit connects that sound with getting what he needs. It does not support claims that only Lulu can help him or that keys are the best fix.

Step 2 · The kid story

Biscuit Knows the Jingle

Biscuit has a routine. When he needs to go outside, he sits by the door and whines. Lulu is the one who walks him every single day. Tommy noticed something funny. When Biscuit is whining and Lulu's keys jingle in the hallway, Biscuit goes quiet for a moment and wags. When Tommy jingles his own keys, nothing. When Grandpa jingles his, still nothing. Biscuit keeps whining. Marcus announced, "Biscuit loves Lulu more than anyone in the world and hates the rest of us." Priya shook her head. "That is too big. All we saw is that one sound makes him pause. The careful guess is that Biscuit has linked Lulu's jingle with the walk he wants." Lulu wrote it down. Biscuit wagged, because somebody, somewhere, had said walk.

Step 3 · Try the model question

Lulu walks Biscuit every day. When Biscuit whines at the door because he needs to go out, hearing Lulu's keys jingle makes him stop whining for a short time. Hearing other family members' keys jingle does not have this effect.

The facts above most strongly support which one of the following?

Step 4 · The courtroom tale

The Case of the Calming Whistle

A zoo keeper was accused of mistreating a sea lion named Pickles. The other side argued that Pickles barks nonstop. Mr. Whitfield called a witness. "When Pickles barks because she is hungry, and this keeper blows her whistle, Pickles goes quiet for a bit. Other keepers blow the same kind of whistle. Pickles keeps barking." "And who feeds Pickles?" asked Mr. Whitfield. "This keeper. Every day." Mr. Whitfield turned to the judge. "Your Honor, I am not claiming she is the only person who could ever calm Pickles. I am only saying Pickles has linked her whistle with dinner. That hardly sounds like mistreatment." The judge agreed, and Pickles barked in approval.

Step 5 · Work the real question

Your answer

How to apply it

List exactly what the facts say: who the group is, what reaction happens, which source stops it, and which sources do not. Then predict the smallest idea that explains why only that source works. Test each choice with the Lunchbox Rule. Cross off choices with absolute words, rankings, or claims about what happens first or most easily, since the facts compare sources, not learning speed or the best possible remedy.
