Writing & Language

After reading the passage, choose the answer to the question that most effectively improves the quality of writing in the passage or that makes the passage conform to the conventions of standard written English. Sometimes the question will include a "NO CHANGE" option. Choose that option if you think the best choice is to leave the relevant portion of the passage as it is.

In recent years, several urban US airports have converted some of the unused land past their runways to provide habitats for honeybees. While airports may seem unlikely locations for beekeeping, many of them, in fact, have the potential to offer ideal conditions for an apiary (a group of beehives). The Lambert-St. Louis International Airport, for instance, hosts an apiary on a 400-square-foot area of land just north of one of its runways. Dutch clover is a preferred food source for honeybees. This area is rich in Dutch clover. The honeybees may thrive there in part because they aren’t exposed to the agricultural pesticides suspected of contributing to Colony Collapse Disorder. Though unorthodox, airport-based honeybee habitats can help to ensure that local regions have healthy populations of honeybees.

A.Dutch clover, a preferred food source for honeybees, is something in which this area is rich.
B.This area is rich in Dutch clover, a preferred food source for honeybees.
C.Rich in Dutch clover, this area also has a preferred food source for honeybees.
D.Dutch clover is a preferred food source for honeybees, and this area is rich in Dutch clover.

答案和解析

答案：B

解析：

Choice B is the best answer because it combines the sentences in a way that creates a logical and smooth progression of information. It continues with the preceding sentence's emphasis on the particular area of land being discussed, mentions that this area is rich in Dutch clover, and then indicates why the presence of Dutch clover is important: it's a preferred food source for honeybees.
