▶ Your Answer : According to the reading, there are three viable solutions to eliminate the emerald ash borers. On the contrary, the lecturer argues that the solutions are not available. He refutes each point made in the passage. First, the reading passage points out that the beetle can be diminished by removing affected trees. Nevertheless, the professor denies such point by positing that this method is ineffective. To elaborate, the symptoms of this disease appear in one or two years. Thus, it is too late to remove the trees when they noticed the affection. Another point that passage puts emphasis on is that synthesis treatment will stop the pest from diffusing. However, the speaker rejects this point by saying that it is greatly problematic. To be specific, the chemicals can contaminate the groundwater. Moreover, It would not be possible if there are a lot of larvae spread. Finally, the reading material asserts that the larvae can be removed by using wasps. On the other hand, the lecturer contradicts this statement by mentioning that there are many things to concern. Professor says the survival rate of wasps will be different depending on their regions. Also, this method can invoke unintended consequences. For example, the wasps would kill other lives. |
