Excellent question and a more than excellent explanation of why the correct answer is what it is.

Thanks - high praise indeed! I must mention though, that when trying to decide how to format the explanation, I came across this excellent post from SQL Kiwi (Paul White?) - which helped me considerably to come up with a clearer and more concise one than I would have done otherwise.
