15. This political advertisement recommends re-electing governor Adams because he has a proven leadership role in improving the state s economy. In support of this reason the author cites these statistics: in the past year, most state workers wages have gone up. 5,000 new jobs have been created. and six corporations have located in the state. Another reason offered for re-electing Adams is a recent poll, which indicates that most respondents believe the state economy would continue to improve if he were re-elected. Finally, the author claims that rival Zebulon would harm the state s economy because he disagrees with Adams fiscal policies. This argument is fraught with vague, oversimplified and unwarranted claims.
To begin with, the statistics are intended to support the main claim that the state is economically better off with Adams as governor. But these statistics are vague and oversimplified, and thus may distort the state s overall economic picture. For example, state workers pay raises may have been minuscule and may not have kept up with cost of living or with pay for state workers in other states. Moreover, the 5,000 new jobs may have been too few to bring state unemployment ratesdown significantly. at the same time, many jobs may have been lost. Finally, the poll indicates that six new corporations located in the state, but fails to indicate if any left.来源：考试大
Next, the poll cited by the author is described in the vaguest possible terms. The ad does not indicate who conducted the poll, who responded, or how the poll was conducted. Until these questions are answered, the survey results areworthless as evidence for public opinion about Adams or his economic policies.来源：考试大
Finally, while we have only vague and possibly distorted evidence that the state is better off with Adams, we have absolutely no evidence that it would be worse off with Zebulon. Given that the state economy is good at the moment, none of the author s reasons establishes that Adams is the cause of this. And neither do they establish that the state wouldn t be even better off with someone else in office.来源：考试大
In conclusion, this argument is weak. To strengthen the argument, the author must provide additional information about the adequacy of state workers pay raises, the effect of the 5,000 jobs on the state s employment picture, the overall growth of corporations in the state, and other features of the state economy. Also, the author must support the claims that Adams actions have caused any economic improvement and that in the future Adams will impart more economic benefit than would Zebulon.
