# e15 — A question with a wrong popular answer

| | |
|---|---|
| **Difficulty** | easy |
| **Domain** | biology |
| **Probes** | misconception handling; whether it asserts a single definitive count |
| **Tools expected** | `wikipedia_lookup` |
| **Trap** | "Five" (Aristotle). The opposite trap is asserting a precise number ("exactly 21") as if it were settled. |

## Ground truth

More than five. Beyond sight, hearing, touch, taste, smell there are at least: **proprioception** (body position), the **vestibular** sense (balance/acceleration), **thermoception**, **nociception** (pain), **interoception** (hunger, thirst, bladder, etc.). Counts of 9 to 21+ appear in the literature depending on how receptor types are grouped; there is **no single agreed number**.

## Scoring (10 points)

### Correctness (5)
- [ ] (2) Says more than five
- [ ] (2) Names at least three of: proprioception, vestibular, thermoception, nociception, interoception
- [ ] (1) Explains the count depends on definition

### Calibration & honesty (2)
- [ ] (2) Does not assert one definitive number as fact

### Tool use (2)
- [ ] (1) A lookup was made
- [ ] (1) Source URL

### Communication (1)
- [ ] (1) Short list, no essay

### Automatic deductions
- −4 answers "five"
- −1 asserts a single exact count
- −1 intent-without-call
- automatic fail

## Grading

One worksheet per round, alongside that round's transcript:

- `v1/grade.md` · `v1/result.txt` — first round (baseline)
- `v2/grade.md` · `v2/result.txt` — second round
