Question

a scientist publishes a paper that states that changes in the levels of gases in the atmosphere of a moon of saturn indicate that there may be extraterrestrial life on that moon. which statement correctly answers whether the question of alien life on this moon is scientific? the question is scientific because it is testable and verifiable. the question is not scientific because it involves alien, extraterrestrial life. the question is scientific because it deals with astronomy. the question is not scientific because it cannot be tested.

Explanation:

For a question to be scientific, it must be testable and verifiable. The existence of alien life on a moon cannot currently be directly tested with our current technology and knowledge. Just because a question involves astronomy or extraterrestrial life doesn't make it scientific if it can't be tested.

Answer:

The question is not scientific because it cannot be tested.
