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. Multiple choice / Real life
B2Choose the basket that satisfies the request
Collocation check: Buy medicine that does not make you sleepy with $12 using a train-station kiosk.
Best answer
Non-drowsy cold medicine and water.
Mini explanation: Shop simulator items test whether the learner follows category, budget, and purpose constraints in English.
Report signal: Short, diagnostic, and reusable across tests, funnels, and practice loops.
2. Sentence order / Real life
B2Tap the actions in the correct order
Collocation check: Follow the English instruction sequence.
Correct order
open the settings tap privacy turn off location sharing
Mini explanation: Instruction following checks whether the user can process action order in English, not just recognize individual words.
Report signal: Short, diagnostic, and reusable across tests, funnels, and practice loops.
3. Multiple choice / Naturalness
B1Decide fast: natural or translated?
Collocation check: "She explained me the rule"
Best answer
Unnatural
Mini explanation: "She explained me the rule" sounds translated. Better: She explained the rule to me.
Report signal: A quick swipe that exposes translated English instantly.
4. Audio choice / Naturalness
B2Listen and choose the word you hear
Collocation check: Did you hear leave or live?
Best answer
live
Mini explanation: The target audio is "live". This generated-vault item isolates one sound contrast so the report can separate listening from spelling.
Report signal: One tiny sound makes the question feel risky and shareable.
5. Audio choice / Listening
B2Choose the implied meaning, not the literal words
Collocation check: Listen to the speaker. What is implied?
Best answer
The speaker is politely saying the decision probably needs to change.
Mini explanation: Softened English often hides criticism inside polite wording. The correct answer captures the practical implication.
Report signal: Short, diagnostic, and reusable across tests, funnels, and practice loops.
