Just because people are standing under the tarp does not mean that the thunderstorm forced them to be under the tarp.


Context: Several people are standing under a tarp; two ladies are facing each other and one has a backpack on with her hands in her jeans pockets while the other one has a cigarette in her hand.
Hypothesis: The thunderstorm forced all of the people to use the tarp for shelter.

Given this context, is the hypothesis true (Yes/No/I don't know)?
