▶ Your Answer :
Both of the given lecture and the article
are about tamarisk beetle. The author of the reading passage explains three
negative factors of the tamarisk beetle, a type of insect that feeds on the
tamarisk tree, aren’t helpful for eradicating. However, the professor in the
lecture counters all three arguments and the reading passage is unreliable.
Firstly,
the article states that controlling the spread of the tamarisk beetle is
difficult. However, the lecture disregards this theory by pointing out that it doesn’t
go where tamarisk tree is absence, since tamarisk beetle only eat this tree. Furthermore,
he adds as it has many predators, spread of the tamarisk beetle is quite
controllable.
Secondly,
the reading argues long time and large amounts of water will be spent to kill
the one. The professor refutes this point by suggesting tamarisk beetles
immediately impact on the tree’s death. Moreover, since these beetles consume
all of leaves, it prohibits the process of photosynthesis, converting from sunlight
to energy. By reducing this process, it decreases the bulk of plants water use.
The
last point made in the reading passage contends that tamarisk beetles trigger the
risk of wildfires. However, the lecturer casts skepticism on this claim by
pointing out that the threat of wildfires made by beetles isn’t that severe, because
government agency keeps managing the potential wildfires area.
