>Not using a different challenge

Like what?

Even something like maths can be claimed to be "viewed generally as a male domain". And once you start accounting for ethnicity and social background I think you would find it incredibly difficult to come up with something that had no possibly offensive cultural baggage.

Actually, maybe the challenge could be to design a challenge that was neutral.

P.S. Considering soccer's limited popularity in the US I doubt most candidates would know the rules.
