▶ Your Answer :The reading passage and the lecture both discuss the topic of emerald ash borer devastating ash trees. Although the reading passage suggests that there are several solutions available, the lecturer casts doubt on points made in the reading by stating that some keys to the problem doesn't seem to be possible. The first point made in the passage is that eliminating the infested tree is one way to solve out the problem. On top of that, due to its distinctive appearance the infested trees are easy to find. Therefore, it will prevent the pests from approaching near the healthy trees. On the contrary, the lecturer expresses doubt on this point by asserting that it is less effective by simply destroying the trees that are infected.
Another point the reading puts an emphasis on is that a chemical treatment is another option. The reading passage furher mentions that with the application of insecticides the tree would absorb its sentiments from the bottom to the top. As a result, this could prevent the borers from reproducing by laying eggs. In contrast, this refutes the lecturer's claim that using chemicals could have drawbacks.
Finally, the claim of the reading passage is that one possible solution is biological pest control.To put it in more detail, wasps that inhabit Asia could kill the emerald ash borers. In fact, introducing these paricular wasps into the wild would help decline the problomatic borer's population. However, this counters the lecturer's statement that there are some flaws in biological pest control.
In conclusion, the professor and the reading passage stand on opposite sides of the debate over the issues of the emerald ash borers harming the trees. |
