Why were Mr. accent man's questions so simple?

Lexi always thought that HOM would be a difficult class. But so far it was easy. So how could they study HOM? Everyone seemed to be saying textbooks and things like that, but Lexi wanted to be out of the ordinary. So that was what she would be. Out of the ordinary and unique.

Raising her hand Lexi began to formulate an answer in her head. "Professor. Can't you talk to old people to find out all sorts of historical stuff. I'm guessing that old people know have experienced some of the things that we read about in textbooks. And if we question old people can't you find out way more than what we read in textbooks. There are different sides to stories right." Because Lexi knew that old people like Granny Thorne knew a lot and went through a lot of things that people read about in textbooks.
