premise: a mass of people looking and moving in the same general direction.
hypothesis: A mass of people moving in the same direction in order to find the object.

explanation_2: They may be moving for some other purpose rather than to find object
explanation_3: We have no idea if they are trying to find an object, they could be doing a number of things.
