▶ Your Answer :
In the reading passage, there is ample support for the author's claim about causes of the red rain. However, the professor in the lecture gives several reasons as a rebuttal to the author's point. First, the professor insists that the blood of bats cannot be the cause of the red rain. In order to form red rain, a large number of bats should be destroyed by thunder. However, any wings or bones of bats have not been found. This refutes the reading passage's claim that the red rain is the result of the destroyed bats' dispersed blood. Second, the professor contends that the volcanic eruption in the Philippines is not a factor of the red rain. This is because the red rain occurred only in the Kerala. If the volcanic eruption was the cause, other countries near the Philippines would experienced it. This refutes the reading passage's assertion that the low PH mixture created from the volcano accounts for the red rain. Third, the professor argues that the pollution from factories did not make the red rain. To explain, there are few factories in that region, so not much chemicals are emitted from them. Besides, if they were the factor of the phenomenon, the red rain would also occurred in cities near the region, not only in the Kerala. |
