Why this activity was chosen

Bloom level: L2 Comprehension: Say in plain English what a short fragment does.
Block Model level: Blocks (step 2 of 4): a logical group of statements read as one unit, such as a loop, a conditional or a function.
Misconception targeted: shown after you answer, so it does not give the answer away.

Before students generate or accept code, they need a verbal model of behaviour. Explanation items make reading a first-class activity rather than a prelude to writing.

AI’s role here: AI may offer a hint about where to start reading, or a second explanation after the student has answered. It must not replace the student's own account of the code.
