Answer:
based on the info that you have provided:
evidence - proof, confirmation, verification are all synonyms.
Explanation:
observations which answer questions - this would have to have been proved with empirical evidence - data evidence that has been proven more than one time. I would not choose this answer.
proof that an idea is true - i would choose this answer due to the wording of "proof"
information for or against an idea - this could be someone's opinion and not have valid data to prove. notice that "proof" is not in this answer. I would not choose this answer.
data - this would be empirical info and I would choose this as an answer.
I hope this helps.
:)
