Question

Which is an example of fact, not historical fiction?

Answer 1

B. Marie Curie....
because it is simply stated fact and not something that could have been exaggerated or made up, like the other 3 answers.

Answer 2

Correct Answer is B

Its very simple. 
All of these couldve been made up but B is something that couldve happened that you could actually check. 

The others could probably be true as well but they are more likely to be used to tell a story
