A few report-ready prompts from this test
These are pulled from the same playable diagnostic. The user can see the kind of answer, explanation, and result signal they will get before committing to the full run.
1. Object hunt / Real life
B2Find the target objects in the scene
Grammar lens: Find these objects in pharmacy shelf: stapler, invoice, charging cable.

Correct order

3. Multiple choice / Naturalness

B2Choose the implied meaning, not the literal words
