indings of a large, national survey that has been conducted annually for the last 25 years. The survey includes more than 200,000 students【C1】______nearly 300 colleges and asks them to【C2】______how their own mental health【C3】______their classmates —for example, is it "above average" or in the "highest 10%"？ This【C4】______unusual methodology typically results in the statistical Lake Woebegon effect in which most people【C5】______to overestimate themselves in relation to others (it refers to the fictional Lake Woebegon, where "all the women are strong, all the men are good-looking and all the children are above average").【C6】______the most recent results indicate that fewer and fewer freshmen feel like they are in top form. in terms of【C7】______stress.
