Hi
The answer is:
Question 3 refers to something that can be measured.
Explanation:
Question 1 refers to the supernatural:
Though question is not given but anything about super natural powers cannot be experimented or proved through a scientific experimentation. There are many ethical concerns as well as limitations of man.
Question 2 reflects a moral or social value.
Moral and social values are very personal things of a society that are based on personal perceptions of which thing is right and which one is wrong. They differ across the regions and can not be scientifically or logically answered since you can get biased. So moral and social value reflecting questions are not scientific.
Question 3 refers to something that can be measured
This can be a scientific question if it refers to something that can be measured, it can be progressed through scientific method to reach a reasonable conclusion.
Question 4 reflects a question that can’t be observed.
Observation is the first step of the scientific method, if one thing cannot be observed it means that it is failed to meet the criteria of the scientific method and cannot be answered scientifically.
Hope it help!
