text: When asking others for opinions they could see what other people think about the topic. First, they could see if other people would do it. Second, they could see whether it is a good idea or a bad one. For example, when buying a house it is good to know about mortgages because some are good and some are bad. Lastly they could see if it is even possible to do whatever they are trying to do. Being able to see what other people would do can help someone make a final decision.
