C is wrong for the following reasons:

1. Climatic shifts can not be able. Person can be able.
2. He is able to solve the problem.
They are able to be sent to the tour.---NOT correct. A revised sentence should be there.

e.g., They are fit for the tour. etc.

A is correct for two reasons:

1. "So XX as to YY" is the correct idiom.
2. GMAT likes conciseness.

Answer is A.
