text: Say you want to get a dog. You ask all of your friends what the best dog is and why. They come up to you and tell about how well the are with kids, if they bark a lot, if they are hypoallergenic, how big they get, and how playful and cute they are. You look at all your options and decide the best dog for you is the toy poodle. When you ask multiple people you get multiple answers and more options to choose from. If you only asked one person then you wouldn't get all the information about all the dogs you might only get information about one.
