Crowds of angry , smelly people were bitching and bumping into each other , and into me , trying to get their copy of whatever textbook they needed for whatever stupid class they were taking . One lady asked to herself out loud " Where is 237 ? " when she was looking at the History section of books .

Question: Why may the people have been unhappy ?
Answer: It was crowded , hot , and difficult to get their books .They needed to find the history books section to get books .They were trying to return textbooks they needed for their classes .None of the above choices .
