We don't know how well it is generalising to your input without knowing the training data. Failure cases however tell us a lot, such as the following:
Input: "If five cats can catch five mice in five minutes, how long will
it take one cat to catch one mouse?"
Output: "If five cats can catch five mice in five minutes, then it will take one cat one minute to catch one mouse. This is because the number of cats and mice are inversely proportional, so as the number of cats decreases, the time it takes for a cat to catch a mouse will increase. Similarly, as the number of mice decreases, the time it takes for a cat to catch a mouse will decrease. Therefore, if five cats can catch five mice in five minutes, then it will take one cat one minute to catch one mouse."
As you can see, it fails at simple logic because it fails to understand that the number of mice aren't fixed in the question. Whereas a human would immediately pick that up because they reason beyond x=5 and y=5.
Are you sure a human would immediately catch this? The question is somewhat ambiguous and I bet if you posed this question to many people they would take the oversimplified non-gotcha approach and simply say one minute for one mouse just like the AI. Of course if you abstract out there are so many other variables at play but within the confines of a simple word question the answer is not necessarily incorrect.
You could probably test this by asking a few friends this question and see what they say. Outside of pure math problems you can get into an infinite regress defining the underlying first principles behind any given assumption.
I am not claiming anything other than the fact that we do not know the training data therefore not much can be inferred about how well it generalises from some success case.
