No, it's necessary to either know that it's a trick question or to have a feeling that it is based on context. The entire point of a question like that is to trick your understanding.
You're tricking the model because it has seen this specific trick question a million times and shortcuts to its memorized solution. Ask it literally any other question, it can be as subtle as you want it to be, and the model will pick up on the intent. As long as you don't try to mislead it.
I mean, I don't even get how anyone thinks this means literally anything. I can trick people who have never heard of the trick with the 7 wives and 7 bags and so on. That doesn't mean they didn't understand, they simply did what literally any human does, make predictions based on similar questions.
