KAPLAN OFFICIAL EXPLANATION:



B

Here you have another “3-2 split,” this time between “to do it” and “to do so,” in the answer choice end- ings. “It” is anambiguous pronoun. You might assume “it” stands for “cure,” but if you substitute “cure” for “it” in the sentence, you get the unidiomat- ic “despite them attempting to do a cure.” If you’re not familiar with idiomatic expressions like “to do so,” learn to recognize them. As you practice sentence correction,write down any usages that are correct but unfamiliar to you. “Doctors” is the subject. You use the pronoun “their,” not “them,” to stand for “doc- tors.” For more discussion of pronouns, see the Grammar Reference.
