premise: A group of people, one holding a yellow and blue umbrella, are standing at the top of some stairs.
hypothesis: A crowd prepares to descend a staircase in the rain.
explanation_1: Just because they are holding umbrellas does not mean it is raining.  Just because they are standing at the top of stairs, does not mean they are preparing to descend. Just because they are at the top of the stairs, does not mean it's an actual staircase.
