In this set of issues, both the reading passage and the speaker discuss the cause of red rain in Kerala. To be specific, according to the reading passage, the red rain in the area of India might be caused by the blood of bats, volcanic eruption in Philippines, or chemical pollution in local factories. However, the speaker contradicts that these explanations have several problems for the following reasons. To begin with, the professor argues that the suggestion that the red rain is the blood of bats is far-fetched. This is because, according to a research, about 5 million bats were necessary to make the amount of the red rain at that time, but this is so extreme and impossible amount. Moreover, any bones or wings of bats were not discovered at that period. These explanations refute the reading passage’s argument that myriad of bats killed by some environmental phenomenon made the red rain. Moreover, the speaker asserts that whether volcanic eruption caused the red rain is not proven. To be specific, if the rain was resulted from the eruption of volcano in Philippines, the rain should have been fallen in Philippines. However, it did not emerged. In addition, other countries between Philippines and India such as Vietnam or Thailand did not also experienced such astounding phenomenon. These reasons cast doubt on the assertion of the reading passage that volcanic eruption in Philippines caused the red rain in India. Finally, the lecturer claims that chemical pollution from factories cannot be the exact reason of the red rain. The reason is that there were few factories in Kerala, and therefore, there were also few chemical material in the area. Furthermore, if chemical pollution were the reason of the red rain, also it would have been fallen much more in cities where there were many factories with no filters in chimney. However, it did not happened. These counter the reading passage’s claim that the red rain is the consequence of chemical pollution from factories in Kerala. In conclusion, the speaker challenges the explanation from the reading passage on account of the reasons stated above |
