GMAT邏輯機(jī)經(jīng)整理：植物入侵.

　　3月2日GMAT換庫，本月由澳際小編為大家收集整理3月份GMAT邏輯機(jī)經(jīng)，現(xiàn)在分享一篇植物入侵的邏輯機(jī)經(jīng)，希望對大家有所幫助，文中觀點僅供參考。

　　有個植物侵入florida lake，本要用h來消滅，h對人動物無害。但使湖中某個植物減少，決定不用問削弱。

　　GWD原題

　　Eurasian watermilfoil, a weed not native to Frida Lake, has reproduced prolifically since being accidentally introduced there. In order to eliminate the weed, biologists proposed treating infested parts of the lake with a certain herbicide that is nontoxic for humans and aquatic animals. However, the herbicide might damage populations of certain rare plant species that the lake contains. For this reason local officials rejected the proposal.

　　Which of the following, if true, points out the most serious weakness in the officials&apos grounds for rejecting the biologists&apos proposal?

　　A The continuing spread of Eurasian watermilfoil in Frida Lake threatens to choke out the lake&aposs rare plant species.

　　B Because of ecological conditions prevailing in its native habitat, Eurasian watermilfoil is not as dominant there as it is in Frida Lake.

　　C The proliferation of Eurasian watermilfoil in Frida Lake has led to reductions in the populations of some species of aquatic animals.

　　D Although Eurasian watermilfoil could be mechanically removed from Frida Lake, eliminating the weed would take far longer this way than it would using herbicides.

　　E Unless Eurasian watermilfoil is completely eliminated from Frida Lake, it will quickly spread again once herbicide treatments or other control measures cease.

　　正確答案：A
