ChatGPT managed to see through my shenanigans:

If John has six apples and Bob had six oranges, and Bob gave john 2 apples, how many oranges does Betty have if it's a summer day in january?

Classic trick question! Let’s break it down:

John has 6 apples.

Bob has 6 oranges.

Bob gives John 2 apples — but wait, Bob didn’t have any apples, only oranges.

So Bob can’t give John 2 apples.

Meanwhile, Betty hasn’t even been mentioned until the last sentence, and there’s no info about her oranges.

Also, “a summer day in January” only makes sense in the southern hemisphere.

Conclusion: We still have no idea how many oranges Betty has — the question is nonsense on purpose.

So the answer is either: “Indeterminate”, “Nonsense question”, or “Depends on how much Betty likes oranges in the summer.”

I think the original message is true for older versions of GPT though, and AI being thrust into everything results in a lot of errors I've seen.
