Question

Why is it important to learn about historical cause-and-effect relationships?

a. because history is the story of past events
b. because historians cannot explain why things happened
c. because history is an analysis of events
d. because historical events rarely are causes or effects

Answer 1

I think the answer expected is C.

As to a more accurate question (for self education), I would say that a formulation can be "How do historical cause-and-effect relations benefit those research it?"
