gre argument 158题目：
The Trash-Site Safety Council has recently conducted a statewide study(5) of possible harmful effects of garbage sites on the health of people living near the sites. A total of five sites and 300 people(1) were examined. The study revealed, on average, only a small statistical correlation between the proximity of homes to garbage sites and the incidence of unexplained rashes(2) among people living in these homes. Furthermore, although it is true that people living near the largest trash sites had a slightly higher incidence of the rashes, there was otherwise no correlation between the size of the garbage sites and people's health(4). Therefore, the council is pleased to announce that the current system of garbage sites does not pose a significant health hazard(3). We see no need to restrict the size of such sites in our state or to place any restrictions(6) on the number of homes built near the sites.
提纲：
(1)For lack of data concerning the total amount of garbage sites and people living near them in the state, the reliability of the study is open to doubt.
(2)The argument treats a lack of proof that current system of garbage sites will pose some extent of health hazard as constituting sufficient proof that it will not pose any significant health hazard.
(3)The Council unfairly assumes that the current health status of people living near garbage sites result from the safety of current system of garbage sites, not other explanations.
(4)The fact that people living near the largest trash sites had a higher incidence of the rashes contradicts the Council’s assertion that there was no correlation between the size of the garbage sites and people’s health.
(5)The result of the statewide study could not sufficiently rule out the possibility that garbage sites do pose significant health hazard in some specific regions.
(6)Certain restriction on the size of garbage sites and number of homes built near the sites would still be necessary in the future although the current system pose no significant health hazard.
