gre argument 194题目：
A recent study suggests that people who are left-handed are more likely to succeed in business than are right-handed people. Researchers studied photographs of 1,000 prominent business executives (3) and found that 21 percent of these executives(1) wrote with their left hand(2). So the percentage of prominent business executives who are left-handed (21 percent) is almost twice the percentage of people in the general population who are left-handed (11 percent). Thus, people who are left-handed(5) would be well advised to pursue a career in business(4), whereas people who are right-handed would be well advised to imitate the business practices(6,7,8) exhibited by left-handers(9).
提纲：
1. The author fails to indicate what fraction of all business persons are left-handed.
2. People who write with their left hand are not necessarily left-handed.
3. The 1,000 executives from the study are not necessarily representative of the overall population of prominent business executives.
4. The photographs in themselves prove little about the causal relationship between left-handedness and the ability to succeed in business, many prominent executives might have risen to their status not by way of their achievements or business acumen but through other means.
5. The facts cited by the author do not indicate that all people who are left-handed are suitable for pursuing careers in business.
6. The author unfairly assumes that people who are right-handed also have strong will to succeed in business.
7. Merely imitating the business practices exhibited by left-handers may not suffice to guarantee business success.
8. Some business activities exhibited by left-handers could not be easily imitated.
9.The author assumes without substantiation that the way in which left-handed people conduct business is the only way to succeed in business.
