Question

Which of the following is an empirical question?
1) Would Martin Luther King, Jr. have been a good president?
2) What is the meaning of life?
3) Was the Civil War necessary?
4) Is there life on other planets?

Answer 1

I think it's the 4th one.

Answer 2

Sentences 1,2, and 3 are all subjective. The 4th is empirical because it can be answered from observation.

Answer 3

Thanks!
