OK. You'll be given the following question. Please do chain-of-thought reasoning.
Which of these sentences doesn't make sense?
Options:
- Sentence A: "the x-ray showed that his arm was painted"
- Sentence B: "the x-ray showed that his arm was broken"

This statement is against common sense because the x-ray would not be able to show paint on the outside of the skin, as x-rays are used to see bones within your body.
Thus, the answer is Sentence A.
