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.
