<p>I’m really confused by the answer explanation to Q. 3 on pg. 63 (passage on pg. 57). The book says choice D is incorrect because the sentence “does not…describe how the citrus beetle was initially discovered.” Yet the sentence says, “The citrus longhorned beetle was discovered on a juniper bush in August 2001 in Tukwila, Washington.” Can anyone explain why D is wrong?</p>
<p>It doesn’t say HOW it was discovered, but rather WHERE. So D isn’t right. Even if it is somewhat true, the inference made by choice B is MORE correct. The first sentence emphasizes how the citrus longhorned beetle is a cousin of the Asian longhorned beetle, and that the Asian one has done a lot of damage. Therefore, you can infer that the citrus beetle, which is related to the Asian beetle, would also be harmful to the US.</p>
