The woman and children are described together, and adults are ordinarily in charge of children, so to say the woman 'has' these children is not unreasonable; in order to watch through a window one must be somewhere by it.


Context: A woman and two children watch through the window as workers put tree branches into a wood chipper.
Hypothesis: A woman has two children by the window

Given this context, determine if the hypothesis is true (Yes, no, or unknown)?
