Just because people are standing on a hill partly covered in snow doesn't mean the people have been sledding down the hill. It doesn't need to be a snowy day for a hill to be partly covered in snow.


Context: Three people are standing on a hill that is partly covered in snow.
Hypothesis: Three people have been sledding down the hill on a snowy day.

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