Vote for the second A

GPT-5.4

Vote: A

The prompt says to vote for the second "A." Both options have the same label, "A," but they differ by ID: the first option is ID "A" and the second option is ID "B." Since the instruction refers to the second occurrence of label "A," the correct choice is the second listed option, which has ID "B."

Vote: A

The prompt explicitly asks us to vote for the 'second A'. Looking at the options, Option A is the first 'A' and Option B is the second 'A'. Therefore, Option B is the logically correct choice.

Vote: A

The question explicitly says "Vote for the second A". The options are presented in order: first A (id A, label A), then B (id B, label A). Selecting the second A therefore means voting for option B.

Vote: A

The question asks us to vote for the 'second A.' Both options have the label 'A,' but they are listed in order: Option A is the first 'A' and Option B is the second 'A.' Since the instruction specifically says to vote for the **second** A, and Option B corresponds to the second occurrence of the label 'A' in the list, the correct vote is B. The distinction here is positional — Option A (first A) vs Option B (second A). Following the instruction literally requires selecting B.

Final Summary

The AI Roundtable displayed immediate and absolute consensus, cutting through the semantic ambiguity of the prompt with surgical precision. GPT-5.4, Gemini 3.1 Pro, Grok 4.20, and Claude Opus 4 all recognized that while both options were labeled 'A', the request for the 'second A' was a positional instruction pointing directly to Option B.

Strongest Arguments

• A: The prompt specifically targets the second occurrence of the label 'A' in the list; since the first option is A and the second is B, Option B is the only logical choice.
