A group of 1,000 students was randomly selected from three high school

A group of 1,000 students was randomly selected from three high schools in a medium-sized city and asked the question, “Do you plan to finish your high school education?” More than 89 percent answered “Yes.” This shows that the overwhelming majority of students want to finish high school, and that if the national dropout rate among high school students is high, it cannot be due to a lack of desire on the part of the students.

The reasoning of the argument above is questionable because the argument

(A) fails to justify its presumption that 89 percent is an overwhelming majority

(B) attempts to draw two conflicting conclusions from the results of one survey

(C) overlooks the possibility that there may in fact not be a high dropout rate among high school students

(D) contradicts itself by admitting that there may be a high dropout rate among students while claiming that most students want to finish high school

(E) treats high school students from a particular medium-sized city as if they are representative of high school students nationwide
