Question

A body of knowledge must be _________ in order to be considered science.

realistic and reliable.

observable and testable.

factual and testable.

believable and reliable.

Answer 1

B

Answer 2

It must be observable and testable for the following reasons:

it doesn't have to be "realistic", because not all science (in it's beginning stages anyway) is realistic. If all science was realistic, we would never learn anything new!

it doesn't have to be "factual", because not all science is facts at the beginning. It can also be working theory.

it doesn't have to be "reliable". Science can fluctuate, so therefore reliability would not make it science.
