text: If you want someone's advice and you only ask one person, that's won't be as much as good advice if you asked many people. If you want to know what song you should listen to, and you ask one person and they tell you something way different from yours, and which you don't like. It wouldn't be a good option for you. If you ask 10 people and they give you a lot of variety you can have options. It better because if you ask one person you have no variety, but if you ask more people you have variety and options.
