When it comes to pollution, there are no effective barriers. Toxic insecticides that have been prohibited in many countries are being transported by the wind to nations where they are still allowed, according to studies. DDT and toxaphene have been discovered in far-flung locations such as the Yukon and other Arctic regions. This paragraph provides the strongest evidence for
A. DDT and other harmful insecticides have not been banned worldwide.
B. Polar climates receive more pollution than warmer climates.
C. DDT and toxaphene are the world's two most hazardous pesticides.
D. Even a global ban on harmful insecticides would not be enough to stop DDT pollution from spreading.
Answer:A
When it comes to pollution, there are no effective barriers. Toxic insecticides that have been prohibited in many countries are being transported by the wind to nations where they are still allowed, according to studies. DDT and toxaphene have been discovered in far-flung locations such as the Yukon and other Arctic regions. This paragraph provides the strongest evidence for
A. DDT and other harmful insecticides have not been banned worldwide. B. Polar climates receive more pollution than warmer climates. C. DDT and toxaphene are the world's two most hazardous pesticides. D. Even a global ban on harmful insecticides would not be enough to stop DDT pollution from spreading.
Explanation: The second line supports this decision by stating that hazardous insecticides are still authorised in some nations. Choice b is incorrect because, despite the fact that polar regions are referenced in the paragraph, there is no evidence that warmer locations are not affected in the same way. Option c receives no support. Choice d is ruled out since no evidence exists that DDT and toxaphene are the most harmful. Option e is the most unreasonable.
