I have to agree with every one else. The select statement is confusing.

First you start off with the declaration

"What values are returned for Test 1 and Test 2? " which is invalid because there are 3 columns.

Then "The values are listed as ID, TEST1, TEST2. For example: "

Then a four column select. What was the point of making a four column select, just make it line up with the answer.
