▶ Your Answer :
Both
the reading and the listening mainly talk about the cause of transient
lunar phenomena, or TLPs. While the reading passage gives three possible
explanations about the topic, the lecturer refutes those ideas by pointing out
some dismissed facts on them.
First
of all, the reading insists that underground gas leaks out through the Moon's
craters, and forms colored gas clouds which are noticed as TLPs. On the
contrary, the listening disagrees with this opinion by mentioning there’s
no such strong causal relationship between the TLPs and lunar craters. To explain,
it is just an accident that TLPs are often observed near craters. This happens because
craters are on the most part of lunar surface. Moreover, the gas clouds might
have not been big enough to be seen from Earth.
Secondly, the article
claims that TLPs occurs when the clouds of dust around the Moon are lit up. Contradictorily,
the professor doesn’t think this as a reliable assumption due to the lack of
evidence. If it is true that dust causes TLPs, there should be huge dust storm
which is conspicuous from the Earth. Additionally, the astronaut who explored
the Moon discovered only little amount of dust.
Finally, the writer
contends that solar flare brings out TLPs. However, the lecturer casts
doubt on this because this claim lacks important data. By comparing the date when
solar radiation and TLPs happened, researchers realized the correlation between
the two doesn’t exist.
