Compare two AI responses against a supplied fact sheet. Which response is better under the rubric?

Instruction: Use only the fictional fact sheet and stated preference rubric. Choose a response and identify the decisive supported or unsupported claims.

Context:

Tests whether factual grounding determines a pairwise preference when a fluent response invents material visiting information.

Fictional practice task

Approved fact sheet: The Harrow Museum opens Tuesday through Sunday, 10:00–17:00. It is closed on Mondays. Standard adult admission is $12. No evening schedule is provided.

User request: "Can I visit on Monday evening, and how much is adult admission?"

Response A: "It is closed on Mondays, so Monday evening will not work. Standard adult admission is $12. Its listed visiting hours are Tuesday through Sunday, 10:00–17:00."

Response B: "Absolutely! Visit Monday at 18:00 for a quiet evening. Adult admission is $12, and you can stay until 20:00."

Rubric: Prefer the response that answers the user's question using only supported facts. A wrong opening day or invented opening time is a material error. Tone and fluency cannot compensate for such an error.

Example Answer

I'd prefer A. It correctly says the museum is closed on Mondays and gives the supported adult admission price of $12. Its listed visiting hours also match the fact sheet, so it answers the request without inventing an evening schedule.

B gets the price right, but it invites the user on Monday and introduces 18:00 and 20:00 times that the source does not support. The Monday claim directly contradicts the closure rule. Under this rubric, that is a material error; friendly wording and one correct detail cannot compensate for it. I'd base my preference on the supplied evidence, without searching for a different schedule for this fictional museum.

Make it your own

Keep the fact sheet authoritative for this exercise. In another task, use its permitted sources and preference rule rather than assuming that tone or length controls the ranking.

Why this works

The answer chooses A and pinpoints the wrong day and invented times, rather than giving both responses an impressionistic fluency score.

Interviewer follow-up

Could B still win because it answers more confidently and sounds more welcoming?

No, not under the supplied rubric. Its confidence makes unsupported visiting advice sound usable, but the advice is materially wrong. A directly answers that Monday evening will not work and supplies the requested price. I'd prefer accurate, supported guidance here rather than reward a friendly invitation that would send the user to a closed museum.

Assessment criteria

Strong: Prefers A and identifies the Monday contradiction and unsupported evening hours, using the rubric's material-error rule.

Adequate: Prefers A because it matches the fact sheet, but does not specify which B claims determine the preference.

Weak: Prefers B for confidence or tone, treats the matching price as canceling the wrong schedule, or searches outside the closed-reference exercise.

A tempting weak answer

“B is better because it says yes, gives a price and provides more detailed visiting advice.”

Why it fails: Its extra schedule details are unsupported and its Monday invitation is false under the fact sheet. More detail does not satisfy the grounding requirement.
