What happens when new data call current scientific explanations into question?
A. Scientists repeat the experiments to prove that the new data are
unreliable.
B. Scientists repeat the experiments to verify results and reevaluate
scientific explanations.
C. Previous explanations are thrown out immediately.
D. Scientists ignore the new data because the findings are clearly
false.

B. Scientists repeat the experiments to verify results and reevaluate

scientific explanations.

Explanation:

This is kind of process of elimination. Scientists don't move onto new ideas with out proof so C it out. They wouldn't just ignore new data so it's not D. Between A and B, B seems most likely because when scientists look into new data they wouldn't necessarily have the mindset of trying to prove that it is unreliable. They just want to confirm and learn.

I know this is late for an answer but I wanted to provide one anyway. :)
