Science writer: Studies indicate that North Americans are becoming more lethargic. One researcher has concluded from these data that fast-food consumption has an adverse effect on people’s health. In the early 1970s the average North American family consumed one fast-food meal a week, while in the 1990s an average family consumed one fast-food meal a day. However, few lethargic adults exercise regularly, and lack of exercise can contribute to lethargy. Thus, the lethargy studies do not settle the question of whether fast food is unhealthy.

Summarize Argument: Counter-Position
The author concludes that certain lethargy studies don’t settle the question of whether fast food is unhealthy. This is a response to a researcher who concluded that the lethargy studies show fast food is unhealthy. The author points out that even though there is evidence that a rise in lethargy is correlated with an increase in the number of times a typical family eats fast food, the true cause of the increase in lethargy might be a lack of exercise.

Identify Conclusion
The conclusion is the author’s assessment of what the lethargy studies do not prove: “[T]he lethargy studies do not settle the question of whether fast food is unhealthy.”

A
A lack of regular exercise is one cause of lethargy in North Americans.
The author only suggests that lack of exercise might be a cause of lethargy. He doesn’t say that it is a cause.
B
High consumption of fast food is a health risk only when combined with a lack of regular exercise.
The author never asserts that lack of exercise is required in order for fast food to be a health risk. He only concludes that the lethargy studies are inconclusive on whether fast food is a health risk.
C
The researcher’s data show that the consumption of fast food is not the main cause of poor health in North Americans.
The author never asserts that fast food is not the main cause of poor health. He only suggests that it might not be the cause of an increase in lethargy.
D
The lethargy studies failed to consider one probable cause of lethargy.
The author never asserted that lack of exercise was a “probable” cause of lethargy. He only suggested that it might be a cause.
E
The researcher’s conclusion was not adequately justified by the lethargy studies.
This is a paraphrase of the last sentence, which is the conclusion. The “researcher’s conclusion” refers to the researcher’s belief that the studies show fast-food hurts people’s health. The author concludes that the studies do not prove that belief.
