This helped me realize that I have been having with confusing sufficient condition and necessary conditions. Explaining that you can't go "backwards" against an arrow now makes sense why I selected the incorrect answer and further why C is the correct answer.

1. Not all singers are songwriters. After all, songstress Whitney Houston did not write the lyrics to her own songs.

2. Those who are members of the recreation center have to either live in the town of Utopia or work in the town of Utopia. Wanda is a member of the recreation center, but does not live in the town of Utopia. Therefore, Wanda must work in the town of Utopia.

3. There is a bite missing from Maria's sandwich. Maria's husband is washing grease off his hands and let out a large belch. My hypothesis is that Maria's husband took a bite from her sandwich.
