Unclear Analogy for Attention Check

My way is correct just like your way. My method is not over-complicating.

A question in general can have more than one answer. It depends on the subject of the question. For example, "what do people eat?". We eat meat, fruit, and vegetables. Those are three answers.

As for this particular attention check, it has two answers. You must remember items can have multiple relationships. Yes, libraries contain books. Books contain pages. That's a logical connection with those relationships.

On the other hand, libraries include books. Books include covers. Books include pages. See what I did? The word, include means containing the parts of a thing or system. From relationships from my point of view and logic, cover would be a correct answer.
