Which of these are Yellowstone’s most popular points of interest?

This is a perfect question to learn how to figure out the right answer even if you are not sure of which one to choose. If you think about it mountains and meadows are very common so people would not travel that far to see them. That leaves glaciers and geysers. These are very uncommon but there are actually glaciers all over the world. Where else do you see geysers? Just about no where so that has to be the right answer. The answer is geysers.
