2. Mud from a lake on an uninhabited wooded island in northern Lake Superior contains toxic chemicals, including toxaphene, a banned pesticide for cotton that previously was manufactured and used, not in nearby regions of Canada or the northern US, but in the southern US. No dumping has occured on the island. The island lake is sufficiently elevated that water form Lake Superior does not reach it.
問support following hypothesis
A. The waters of the island lake are more severely polluted than those of Lake Superior
B. The toxaphene was carried to the island in the atmosphere by winds
我假設是要support"The island is sufficiently elevated..."所以我在想以兩個湖的污染嚴重來比較是否可支持假設,反倒是B似乎支持的是"No Dumping has occured on the island"就讓我有點confused請教各位

我的看法此題應把題意拆成兩部分
1.Mud from the island lake 具有毒物質，卻不是dumping造成。
2.但照道理說The Lake Superior的水應該無法達到the island lake的高度。
問支持...
就如B所說，是風把有毒物質吹上the island lake

反倒是B似乎支持的是"No Dumping has occured on the island"就讓我有點confused請教各位

上面這句話我的理解：因為no dumping has occured表示也沒發生任何傾倒行為在the island lake，所以排除dumping的原因：是風把有毒物質吹上the island lake。

open to discuss...
