▶ Your Answer :
In the reading passage, there is ample
support that Kerola's past red rain was a plausible and rational appearance.
However, the professor in the lecture gives several reasons that there are problems
among them, and the happening seems to be false.
First, the reading passage shows that blood
of bats can be a factor of the red rain since there were many bats in India and
evidence such as cells of bat DNA were found there. However, the professor contends
that it is a far-fetched idea. In order to cause such a massive red rain,
approximately 5 million numbers of the spontaneous demise of bats should have
happened, which seems unrealistic. Plus, at the site, there were no bones or
wings, which could be more direct evidence of bats' death.
Second, the reading passage alleges that a
volcanic eruption can be another reason for red rain since dust from the
eruption has blown to India and fell in rain. On the other hand, the professor
insists that it is not proven. Above the reading passage's assertion could not
prove the absence of red rain in countries such as Vietnam or Taiwan that are
located between India and Philippines.
Lastly, the reading passage asserts that
pollution from the factories' chimney can be one reason for red rain. However,
the professor refutes this statement. There were few factories in India. Plus,
since Kerala is not a big city, it is less plausible to happen some pollutants
in the area, which straightly opposes to the reading passage's content.
