Answer 1

I would think it is a. A measurement of growth patterns of crystals in space

That is something that is being tested the other ones are just questions and surveys .

Answer 2

I belive that the answer is (a) because it can be scientifically proved. Whilst the others are just a matter of people's opinion's.

I hoped that i could help with your road to success.
