▶ Your Answer :
The lecturer argues that causes of whales being
stranded on the beach aren’t obvious. This contradicts the reading passage’s
claim that there are a few possible reasons about this phenomenon.
First, the lecturer argues that it isn’t
accurate to explain these stranding for wind patterns. Actually, the stranding
of whales happened all around the world, including diverse wind patterns. For
example, in the western coast, the wind flows away from the land. This counters
the reading passage’s claim that wind patterns cause the flow of food sources,
leading to whales stranding.
Second, the lecturer claims that illness
doesn’t explain the reason completely. It isn’t enough to explain why healthy
whales suddenly become sick. In addition, whales can swim back well by themselves
when they return to water. This casts doubt on the reading passage’s claim that
whales helplessly lie on the beach because of diseases.
Last, the lecturer points out that the
problem of sonar beams doesn’t explain all kinds of whales stranding. Every
whale uses same method of navigating, but some whales are stranded while others
do not. Also, it isn’t a case that whales which frequently go to shallow beach
become stranded. This refutes the reading passage’s claim that shallow
coastlines disturb whales navigating.
