Barron's How to Prepare for the Test of English as a Foreign Language:

It is important that the TOEFL office _______ your registration.
A. will confirm B. confirms C. confirm D. must confirm

The given answer is C.
My question is whether 'confirms' can also be used in American English, respectively in conversation, in ordinary writing and in regulations.


I would very much appreciate it if you could help me with a bit detailed information.

[Barb_D]

We use the subjunctive a bit more in the US (I'm told) than elsewhere, so "confirm" is what I would say and the "official" answer.
That said, I"m sure a lot of people do say "confirms.

[emsr2d2]

In a test, "confirm" would be expected. However, as Barb said, you will hear "confirms" as often, if not more often.

Thank you very much, Barb and emsr. Then how would most Americans feel about this test question? Would they think it correct, reasonable or anything?

NOT A TEACHER & NOT AN AMERICAN

I think it's a bad question. I don't see why "confirm" is the more correct answer.

You can say, 'It's essential that everyone be here on time*' and 'It's essential that everyone is here on time*.' Both are acceptable and neither of these sentences is any better than the other.
