I agree with the others here. The proffered answers were not adequate because there was too much ambiguity on what should be considered "output". If you are expecting that "output" is the result of the SELECT, then there was no correct answer. If you expected "output" to mean both messages and results, then the supposed correct answer is also not accurate.

This question was just poorly worded. Try... Catch is a concept that is very important to understand though, so I appreciate the intent.
