Which of the following statements about the Homestead Act is INCORRECT:?

It's called reading the text book. Some multiple choice tips in general: look for the two answers that contradict each other. In this case, it would be B and D, since "the great majority of land went to pioneering settlers" (most of the land went to individual people) and "a lot of the best land went to speculators and railroads" (most of the land went to corporations) can't both be true. Now I will leave you to figure out for yourself which is untrue, B or D.
