5月23日SAT语法每日一练题
Some plant pathologists have turned to genetic engineering to devise new ways of responding to botanical diseases. Plant pathologist William Powell, for instance, teamed up with forest biologist Chuck Maynard to restore North America's population of American chestnut trees, which was decimated in the early 1900s by a fungus known as chestnut blight. A fungus, C. parasitica, contributes to the growth of cankers on the trees' trunks; these cankers, in turn, prevent a tree from transporting water from their roots to their branches and leaves. To render American chestnut trees resistant to the blight, Powell and Maynard experimented with altering the genetic makeup of the trees. The resultant genetically engineered trees are called Darling 4 American chestnut trees, and during the first 15 weeks after infection with chestnut blight, they grow cankers that are much smaller than those that grow on American chestnut trees.
以下哪项替换划线处内容更为合适
A.NO CHANGE
B.trees
C.that tree
D.it
答案：B
解析：
Choice B is the best answer because it maintains agreement between the plural noun "trees" and the plural pronoun "their." This choice is also consistent with the first part of the sentence's use of plural trees.
