Question

Environmental stresses at high altitudes include A. increased temperatures. B. lower humidity. C. decreased UV radiation. D. quick ascent.

Answer 1

its either a or c .....

Answer 2

I think it's B and C because a and c don't make sense because if there is higher temperatures it'll be more sun so you'll need sunglasses which protect you from UV radiation. It won't make sense so pick B or C.
