▶ Your Answer :
Both the lecture and reading hold
different positions(,) respectively(,) on the issue of whether volcanic
activities caused K-T extinction or the asteroid collision did. The lecture’s
argument is formed around many points that are against reading passage’s
assertion /in direct contrast to the material in the reading passage.
First off, the reading passage mentions
that K-T extinction was triggered by volcanic activities because the semblance
of the Deccan Traps indicates outpouring of lava. However, the lecture rebuts
this by claiming that the massive extinction was a the result of an
asteroid collision. She supports this argument with the fact that such massive
craters cannot be produced by volcanic activities. The physical features of the
craters are actually similar to those of asteroids.
Also, the reading passage argues that the
devastating eruption caused dust shoot into the air which cooled the earth and
the cooling effect led to KT-extinction. On the other hand, the lecture refutes
this by arguing that the result was not precipitated by the eruption because
iridium was found in the soil of that period. While iridium is one of major
compositions of asteroids, volcanic eruptions do not release this substance.
Finally, the reading passage suggests
that coincidence of the Deccan Traps creation and K-T extinction are is
the proof of its claim. (이 문장에서 주어가 coincidence of the Deccan Traps creation 과
K-T extinction 로 2개 아닌가요? 그렇다면
복수형 be동사, are, 을 써주세요~ ^^) In contrast, the lecture counters this claim/idea point by pointing
out that the formation of the Deccan Traps took over millions of years, while the K-T
extinction occurred only for thousands of years. Therefore, it is evident that
the coincidence cannot be the base of the reading passage’s
assertion.
In conclusion, the reading passage
presents three aspects with regards to the K-T extinction. However, the lecture
makes it clear that none of these points justify the reading passage’s
argument. |
