Following the traditional order of service at a formal banquet setting, the caterer would serve the entrée after serving the a. appetizer. b. second wine. c. salad. d. soup.

A, the appetizer. I'm wondering how this is an AP question, but that's none of my concern.

See, the appetizer is what you start off with before the entree itself. Salad and soup fall under this category. 

Pressure and heat that's what i think( don't report if wrong)
