A woolly mammoth stuck in an infinitely deep tar pit  means as if it were stuck in something viscous and gluey, and would not be able to move.
Context: It was if she were stuck in something viscous and gluey, but she was still pushing as hard as she could.
Hypothesis: She was still pushing as hard as she could, but it was as if she were like a woolly mammoth caught in an infinitely deep tar pit.

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