c. the only drink made with eggs and milk; passes
d. eggnog is a drink made with eggs and milk; does not pass
e. all drinks are made with eggs and milk.

Explanation:

Step1: Analyze set - relationships for Venn - diagram

The sale includes all head - gear and sunglasses are head - gear. So the circle for head - gear is inside the circle for sale, and the circle for sunglasses is inside the circle for head - gear.

Step2: Analyze reversibility of definition

The reverse of "A drink made with eggs and milk is eggnog" is "Eggnog is a drink made with eggs and milk". But there could be other drinks made with eggs and milk, so it doesn't pass the reversibility test.
