▶ Your Answer : In the reading passage there is ample support for the author’s claim that there are plausible theories to explain Red rain observed in the Indian state of Kerala. However, the professor in the lecture gives several reasons as a rebuttal to the author’s point. First, the professor contends that it does not make sense that blood of bats caused red rain. If it were the truth, more than 5 million bats must have died at the same time to make that much blood Moreover, no remains such as bones and wings were found in Kerala. This casts doubt on the reading passage’s claim that red rain was caused by blood of bats, killed by a metheor burst or thunderstorm Next, the pf insists that it is not proven that volcanic eruption in the Philippines results in red rain. If acidic dust from volcanic activities was the reason, red rain should have been observed in other regions in the Philippines too but only Kerala experienced the rare weather phenomenon. Also, countries located between the Philippines and India such as Vietnam and Malaysia have not experienced red rain. This counters the reading passage’s assertion that volcanic eruption accounts for the red rain since it created a lot of acidic dust, changing the PH level of rain. Finally the professor argues that it is far fetched to say that pollutants from local factories made the red rain possible. There were not many factories in Kerala so, there were not much chemicals to be released. On top of that, there was no sign of red rain in other cities with a lot of factories. This refutes the reading passage’s suggestion that contaminants from nearby factories, bonding with moisture in the air, caused red rain |
