Answer to Question 1

TRUE

Answer to Question 2

The light of both telescopes is combined with an optical interferometer to give resolution of the pair equal to the separation of the two telescopes on the top of the mountain, much better than can be done with any single telescope on its own.

Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
