which of the statements below is a scientific claim?

Question

1. human beings will never set foot on the moon. 2. some of the laws that govern nature cannot be detected by scientists. 3. it is quite possible that in some other galaxy the laws of physics are fundamentally different than the laws we are acquainted with in the galaxy. 4. none of the above statements are correct.

please explain your answer.

Answer 1

For a statement to be "scientific" it must be able to be tested. 2 and 3 are obviously untestable and therefore so is 4. One barely qualifies because it has an indefinite time limit, so if it said another Galaxy instead of moon it would be unprovable to so long a time as to be meaningless. Did you make a typo in 4 and type correct instead of scientific?
