text: I think people need multiple choices, so they could get a better vision on a topic that they wanted to know about. Because usually one topic is not enough to really imagine what that thing is that you wanted to know. it also helps the one person have an idea of what they were looking for. It can also make the other person feel good about them selves knowing that they just helped someone. You could also put all of the ideas together and find out which one is the best possible answer. for what you are looking for.
