I'm grateful for the point. It was easy for me - which I can't say about too many questions, but I'm especially glad I didn't second-guess myself into a wrong answer by being suspicious and thinking that the obvious answer was somehow a trick.
Also, I have two side hypothetical questions:
1. What would happen if tempdb could be set to bulk-logged or full recovery? What would be the consequences for the SQL Server system (performance, etc.)?
2. Are there ways to audit tempdb processing that are (1) feasible and (2) might be desirable for those wanting to track that activity for security reasons, given that it can't be logged fully and gets recreated every time SQL Server restarts? Or is that just a pointless idea stemming from my having seen a few CSI episodes?
A SQL query walks into a bar and sees two tables. He walks up to them and says Can I join you?
