Just because a derby girl is in full regalia doesn't mean she is in competition. Just because she is mainlining her balance doesn't mean she is doing a fierce activity.

Hypothesis: A roller derby girl is in a fierce skating competition.

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