A developer is using a few-shot prompt to teach a language model to solve simple logic puzzles. The model's performance is inconsistent. Below is one of the demonstrations included in the prompt:

Input: 'If all Wibs are Wobs, and all Wobs are Wubs, are all Wibs also Wubs?' Output: 'Yes.'

Analyze this demonstration. Identify a key weakness in its structure and explain how you would modify it to more effectively guide the model's reasoning process.
