题目题材：医疗保健，商业
gre argument 90题目：
The following appeared in an editorial on health problems in the country of Corpora.
Some pharmacies now feature ultrasound machines that screen for an elevated risk of stroke. For a fee, a technician presses a probe against the neck to determine whether any plaque has thickened the walls of the main artery leading to the brain. Researchers have shown that a thickening of artery walls is associated with elevated stroke risk, and such scans typically find that anywhere from 5 to 20 percent of clients have detectable plaque. All pharmacies should offer this service, because early detection of increased risk for stroke will encourage clients to consult with their doctors and make important life-style changes to reduce their risk of having a stroke. This in turn will cause a decrease in overall medical costs in Corpora.
提纲：
The author fails to establish a causal relationship between the thickening of artery walls and elevated stroke risk.
Since the thickening of artery walls and stroke could be caused by many reasons, the service may not sufficiently find all people who have risk for stroke.
The author fails to consider the feasibility of offering the service for many pharmacies.
Other methods of detecting risk for stroke are possibly available.
The clients who used the scans may not be representative of all people living in Corpora.
The assumption that all pharmacies need to provide such service is not guaranteed.
The author unfairly assumes that clients who have been detected to have plaque will trust the detection, and will consult with doctors and make changes in life-style as a result.
No evidence could guarantee that changes in life-style could reduce the risk of having a stroke.
The author does not analyze the constitution of medical costs in Corpora, thus we cannot guarantee that the cost will definitely decrease after the proposal is adopted.
The author ignores the expenditure of treatment for stroke in people who are diagnosed as stroke, thus the medical costs would not decrease.
