### HideShow timer Statistics

An annually conducted, nationwide survey shows a continuing marked decline in the use of illegal drugs by high school seniors over the last three years.

Which of the following, if true, casts most doubt on the relevance of the survey results described above for drawing conclusions about illegal drug use in the teen-age population as a whole?

(A) Because of cuts in funding, no survey of illegal drug use by high school seniors will be conducted next year.

(B) The decline uncovered in the survey has occurred despite the decreasing cost of illegal drugs.

(C) Illegal drug use by teen-agers is highest in those areas of the country where teen-agers are least likely to stay in high school for their senior year.

(D) Survey participants are more likely now than they were three years ago to describe as "heroic" people who were addicted to illegal drugs and have been able to quit.

(E) The proportion of high school seniors who say that they strongly disapprove of illegal drug use has declined over the last three years.

Hi,
A survey has shown that illegal use of drugs among high school children has declined over the last three years.
We are asked to choose an answer choice that would weaken the survey itself.
Option C fits the bill because it shows that the group chosen for survey is not right. Teenagers who are indulged in the illegal usage of drugs are not a part of this survey.
