medium · LSAT Logical Reasoning

Which flaw does this reasoning commit?

1. It commits modus tollens by validly negating the rule's antecedent from the missing feature here.
2. It infers the triggering category from the satisfied feature, though other categories share that feature.
3. It reasons in a plain circle by quietly assuming the very conclusion that it claims to establish.
4. It denies the antecedent, concluding that no shot clock at all follows from its not being a professional game.
5. It wrongly assumes that a shot clock is found exclusively within professional basketball games everywhere.
