text: Just think, what if you asked someone for advice and they weren't completely sure what to say. They wouldn't want to let you down and not help you at all. So they could give some bad advice because they didn't know what to say. If you asked multiple people then someone might understand you more than others and they might give you better advice. If you ask multiple people the same question then they might all give you the same answers and that would show you that that's what you should do.
