I'd say a).
Why? You get one question per
packet on Brandi Chastain (who scored the winning PK
goal for the US women's soccer team). It seems like
the subject is relevant enough to merit inclusion at
least once (since so many teams consider it
relevant).
If a) gives people an advantage, rewrite the
question on the same topic, but with different answers
than either one. A tossup might have its answer
Brianna Scurry (US GK), while a bonus might be Denmark,
Nigeria, North Korea, Germany, Brazil, China (US opponents
in order). Here you retain the general topic, but
kick out the obvious answer - the person who wrote the
question will probably get the answer if they follow
women's soccer, but they won't simply parrot what they
wrote.
