Committed to "learn" vs. Committed to "learning"

[sorkroto]

When I was studying at a language institute in the States 2 years ago, I heard teachers tell me that I was committed to "learn". As anyone would do, I remembered the compliment I received and remembered the phrase . :) However, one of the mock tests I was taking just now told me I was wrong for choosing the base form of verb after "committed to".

The sentence was:

Dr. Tanaka is committed to for children in need.

I chose "care", but the answer was "caring" because "be committed to ~ing" is a set phrase. Now I'm confused. I even googled "committed to learn" and "committed to learning" separately, and both showed some results containing each of the phrases.

Could somebody please tell me how I can differentiate those two???

Thanks in advance!

I don't understand why you were told that "committed to learn" is correct. I would have said "committed to learning" and would use the -ing form of the verb in almost every sentence I can think of.
