"issuing a loud, angry complaint about the meal you just had in a restaurant" is the answer :)
WHAT? I? DONT? UNDERSTAND? YOU? SO? PLEASE? FORGIVE? ME?
B. One of your troop members began to cry.
It doesn't explain why he is crying, and is the most suspenseful, but one could argue it was C, because they could have going the wrong direction, but B is the most suspenseful due to the crying and emotion in it.
Hope this helps, even though I just debated aloud.
In any speech or essay, the introduction is the first part. Here, things like hook, subject, title, and author are included (if applicable.) The introduction also has to be catchy and list main points for later stages/body paragraphs. Good writers should always keep the introduction somewhat short like the conclusion, because most of the information should be in the body.
Hope this helps!
