Answer:
A) A gymnast
Explanation: I have found the types of student that are in this middle school.
a. Tanner, a gymnast, is a fanatic about exercise and has lost a lot of weight during the six months since school started. Mr. Thomas rarely sees him at lunch.
b. Brit seems to be on an emotional roller coaster. Mr. Thomas has noticed that one day she may gorge on her lunch, a friend's lunch, and extra snacks, but other days she skips lunch.
c. Carson is painfully thin. In class photos, he appears to be the thinnest boy in his classroom every year. When Mr. Thomas visits the lunchroom, he sees Carson eating a regular school lunch everyday.
D. Shawna is about thirty pounds overweight and is always on a diet. She tells Mr. Thomas that she has tried one diet after another but nothing has worked for her.
