从老外论坛上学到的结论:

What this means for you, the student, is that it’s a complete waste of time for you to question any official answer to a problem published by GMAC. Indeed, the only appropriate response to a correct answer that you find surprising, illogical, or “ugly” is this:
“Wow, that’s unusual. I guess I’ll have to recalibrate the way I think about that, because now I know I can do _____.”
Again, this is the ONLY way to respond to surprising constructions, solutions, and so on in officially correct answers. If you respond by questioning or doubting the validity of such answers, or, worse yet, actively trying to dispute that validity, then you are at best sidelining your studies with needless detours, and at worst confusing yourself.

On official problems, correct answers are correct.
That’s it.

There may be answers that you don’t like – I, for one, have been positively disgusted by a few of the officially correct SC answers I’ve seen – but you’ve got to learn to play by GMAC’s rules.
