Inference (Most Strongly Supported)

The one idea it tests

When the label is swapped and the choices swap with it, the label moved at least some people.

The basic logic

Two groups see the same two things in an unchanged order, but with the labels switched. Each group picks whichever one wore the fancy label. Use the Lunchbox Rule: the safe conclusion is a modest one, that the labels influenced at least some choosers. Watch for answers that say all, most, or always.

Tiny words that decide it

“some”
“everyone”
“swapped”

Playground logic

Ms. Rivera's two classes taste the same two sandwiches, but the 'Grandpa's famous recipe' tag is moved to the other sandwich for the second class, and the vote follows the tag. The lunchbox holds only this: the tag swayed at least some kids.

Step 2 · The kid story

The Sandwich Tag Test

Ms. Rivera brought two sandwiches to class. She said, 'This first one is Grandpa's famous recipe. The second came from a vending machine.' Every kid voted for the first one. Then she walked next door to Ms. Lin's class with the same two sandwiches, served in an unchanged order. Now she announced, 'The first came from a vending machine. The second is Grandpa's famous recipe.' Every kid there voted for the second one. Marcus gasped. 'So vending machine food is always terrible!' Priya shook her head. 'The sandwiches never changed. Only the tags moved. And the votes moved with the tags.' Lulu wrote on her clipboard: 'At least some kids picked the tag, not the taste.' Kevin raised his hand. 'Did either one have pineapple?'

Step 3 · Try the model question

Ms. Rivera showed one class two sandwiches, calling the first a famous family recipe and the second a vending machine snack. Everyone chose the first. She showed another class the same sandwiches in an unchanged order, but swapped the descriptions. Everyone there chose the second.

The facts above give the best support to which statement?

Step 4 · The courtroom tale

The Case of the Swapped Price Tags

A shopper sued a shoe store for 'tricking' customers. The store manager admitted a test: on Monday, two identical pairs of shoes sat side by side, the left one tagged 'designer' and the right one tagged 'bargain bin.' Every buyer took the left pair. On Tuesday, same shoes, same spots, tags swapped. Every buyer took the right pair. Mr. Whitfield adjusted his suspenders. 'Your Honor, I will not claim every shopper is foolish, or that nobody looks at shoes. I claim only this: the tags moved at least some buyers.' Judge Ines Halloway nodded. 'The shoes never changed, but the choices did. That much is proven. Nothing more.'

Step 5 · Work the real question

Your answer

How to apply it

List what stayed the same across both runs and what changed. If only the description changed and the choice flipped with it, the description must have mattered to someone. Choose the answer that claims just that much. Cross off answers using 'all', 'most', or claims about what would happen in a different setup the passage never tested, and answers about whether the descriptions were true.
