Catherine goes to her local movie theater only to see romantic comedies. Since Catherine did not go to the movies yesterday, there is not a romantic comedy playing at her local theater.

The reasoning above is flawed because the evidence

does not suggest that Catherine goes to see every romantic comedy that plays at her local movie theater
implies that Catherine is uninterested in most types of movies
does not indicate whether Catherine watches only romantic comedies at home
suggests that Catherine’s local movie theater hardly ever shows romantic comedies

I'll be glad to check your answer.

suggests that Catherine’s local movie theater hardly ever shows romantic comedies

The correct answer is: does not suggest that Catherine goes to see every romantic comedy that plays at her local movie theater.

The reasoning above is flawed because it assumes that since Catherine did not go to the movies yesterday, there is not a romantic comedy playing at her local theater. However, this conclusion is not supported by the evidence given. Just because Catherine did not go to the movies yesterday does not necessarily mean that there are no romantic comedies playing at her local theater. It is possible that there was a romantic comedy playing yesterday, but Catherine simply chose not to go to the movies on that particular day. Therefore, the evidence does not suggest that Catherine goes to see every romantic comedy that plays at her local movie theater.
