Hi, Avelone

First I'd like to correct you a little bit

Hi Avelone

You can also say "pointless to try to" in that sentence. Saying "pointless trying to" is not wrong, so that is not the error in the sentence.

The error in usage is "adapt". The correct answer is 'change'.

Hi, Yankee

Does the usage of "trying" in this case suggest some kind of "continuousness" of the action
(as opposed to to try which suggests a single action, one attempt)?

Hi LS

I'd say that would be a reasonable way to describe the difference.
