Any college football player who uses steroids should be banned from competition. The national agency with the responsibility to preserve the natural competitive balance between players enforces rules specifically mandating that no player be allowed to use drugs to gain a competitive advantage. Studies show that steroid users tend to have much greater strength and weight than non-users.
Which of the following statements, if true, would most strengthen the argument?
A. Users of steroids often suffer from acne, extreme nervousness, and reduced sexual potency.
B. Increased strength is more useful than increased weight to college football players.
C. Superior strength and weight give college football players a significant competitive advantage.
D. Steroid use is much more prevalent in college football than in college baseball.
E. Random drug testing of athletes has been shown to be effective in the detection of drug use by athletes.
OFFICIAL EXPLANATION
(C)
Step 1: Identify the Question TypeThe word “strengthen” gives this one away as a Strengthen question.
Step 2: Untangle the StimulusA Strengthen question is built around the argument’s assumption. “Strengthen the argument” means “strengthen the conclusion,” but you’ll be strengthening the argument’s conclusion specifically by affirming its central assumption.
The author concludes that steroid users should be banned from college football. The evidence comes in two parts. First, the rules forbid football players to use drugs to obtain a “competitive advantage.” The second piece of evidence is that steroids cause big increases in strength and weight.
Step 3: Predict the AnswerThe author’s conclusion depends on the assumption that having “greater strength and weight” provides athletes with a “competitive advantage.” (It’s possible that added bulk could be a drawback for a college player; perhaps speed and flexibility are more important.) To strengthen the argument, look for an answer choice that suggests that players derive a benefit from the extra size and strength that steroids provide.
Step 4: Evaluate the Choices(C) matches the prediction perfectly and is the correct answer.
(A) introduces several negative side effects of steroids, all of which are irrelevant to the argument.
(B) offers an irrelevant comparison between increased strength and increased weight.It doesn’t matter which of these two qualities is more important to a college football player; it only matters whether these qualities provide a competitive advantage.
(D) is another irrelevant comparison, this time between college football and college baseball. The argument is about steroid use among football players, so baseball is beside the point. The “prevalence” of steroid use is also irrelevant.
(E) is incorrect because methods of drug detection have no bearing on the argument.It doesn’t matter how players are caught.
