If this is a true or false question, then the correct answer is "true."
It is true that if Maurice has been asked to write a research paper on American abolitionist Harriet Tubman who lived from 1820 to 1913, Maurice must examine the sources he has collected.
This is the correct way to start the essay, researching the proper sources, primary or secondary, to support the arguments of his essays. He has to be aware of the exact information and validity of the sources to have his arguments correct. Otherwise, he could risk the accuracy of the information to be included.
Maurice must collect enough sources and then decide what kind of information best suits the approach of his essay. That is why it is so important that he can write a good hypothesis.
