Passage:
Many nutritionists argue that school cafeterias should ban sugary drinks such as sodas and sweetened juices. These drinks are high in calories but provide no nutritional value, and they are a major contributor to obesity and related health issues in children. Therefore, eliminating sugary drinks from school cafeterias would improve students’ health and reduce obesity rates. Which of the following, if true, most strengthens the above argument?

The argument claims that banning sugary drinks from school cafeterias will improve student health and reduce obesity. Let’s evaluate each option: A) Suggests that students bring their own drinks, which does not support the idea that banning them in school helps. B) States a neutral fact — the availability of alternatives — but doesn't prove the health benefit of banning sugary drinks. C) Directly supports the claim with evidence: removing sugary drinks led to reduced obesity, which strengthens the argument. D) Brings up a financial concern that could weaken the recommendation. E) Suggests that other factors influence obesity, potentially weakening the argument. Therefore, option C is correct because it directly strengthens the link between removing sugary drinks and improving student health.
