C D E
Correct Answer: (A)
18.Constant use of antibiotics to treat infections
both destroys many benign bacteria and encourages
A B C
harmful ones to cultivate even more resistant
D
strains. No error
ENothing should stand out as wrong, but let’s work through each answer choice.
(A) “both” needs to have an “and” and it does: both destroys AND encourages. Let’s check SVA
with the simple present tense verb “destroys.” Who or what “destroys”? The constant use.
Remember to cross out the prep phrase of antibiotics. Singular verb (destroys) singular subject
(use) is a match.
(B) “many” is an adverb modifying the adjective “benign” which is modifying the noun
“bacteria.”
(C) “encourages” is a simple present tense verb that also refers to “the use,” which is singular, so
SVA checks out fine.
(D) “even” is an adverb modifying “more,” which is an adverb modifying the adjective “resistant,”
which modifies the noun “strains.” All good.
Correct Answer: (E)
