I am an English teacher in Japan and I have been coming across a lot of sentences that seem strange to me. I was wondering if you could  answer some questions.

One of the Japanese teachers put this question on a test.

"Her make up is always (       ) to the occasion"

And the answer is "appropriate". This is a question from a English test book.

The teacher asked me if this sentence was strange and I told him yes. Not because it is funny, but grammatically. I would never say "appropriate to" unless it was followed by a verb, for example:

"It is appropriate to bow when meeting someone in Japan."

After thinking about it I told him that I would use "to" before verbs and "for" before nouns.

Is this correct? Is the text book incorrect?

I realize that there are many things that I use as natural English that go against the rules and that this could be my mistake.

Thanks in advance
