Question

Lines of evidence from many fields of study, from fossils to DNA sequences, have been important in developing evolutionary theory. Why is it important to have supporting evidence from a variety of fields?
A. It lends strength to the argument if evidence from a diversity of fields results in the same conclusion.
B. Asking scientists from a variety of fields to test the ideas means more scientists will take an interest in promoting the theory.
C. If a theory can encompass many different fields of study, then financial funding for future testing of the theory would be easier to attain.
D. It is unlikely that scientists will disagree with evidence collected within their own fields, so everyone would find something to agree with.

Answer 1

I think the correct answer is A.

Answer 2

I think the correct answer would be option A. It is important to have supporting evidence from a variety of fields because it would lend strength to the argument if evidence from a diversity of fields results in the same conclusion. It would make the theory more believable since a number of professionals which know more about that subject has the same conclusions and believe in the same idea.
