OFFICIAL EXPLANATIONProject SC Butler: Sentence Correction (SC2)
THE PROMPTQuote:
A new generation of online tools is aiming to create sophisticated shoppers for medical care, but even when people can access new information,
it is not always used effectively by them.
A quick glance at the answers tells us that pronoun/antecedent agreement is a big issue
THE OPTIONS Quote:
(A) it is not always used effectively by them
• the singular pronoun
it agrees with its singular antecedent
information• the plural pronoun
them agrees with its plural antecedent,
people• I don't like the active to passive voice switch from "people can access" to "is not used effectively by them [people]."
KEEP, but look for a better answer
Quote:
(B) this is not used effectively always
•
this is almost never a stand alone pronoun. (I know of one official question in which
this was a standalone pronoun.)
→
this should point to a noun:
this street on the right, not that street on the left
•
always is in the wrong place.
Always is typically placed right before the verb that it modifies and is not as amenable as other adverbs to being placed at the end of a sentence.
→ We should be reading, "this is not always used effectively."
•
this is not used effectively deploys hazy and flabby prose.
ELIMINATE B
(C) its use by them is not always effective• as in option A, the pronouns are correct, but
• we have the same "switch mid-sentence to passive voice" problem as that in A—and no way, really, to distinguish between A and C
KEEP but look for a better answer
Quote:
(D) their use of this not always being effective
• no verb exists in the second clause; we have a run-on
• as in option B,
this as a standalone pronoun is not correct
ELIMINATE D
Quote:
(E) they are not always able to use it effectively
[/quote]
• this construction makes more sense than the constructions in A and C because the previous clause leads with the subject
people, and this option leads with the matching pronoun
they• the switch to passive voice is avoided
• compared to A and C? No contest. Option E is clearer and more parallel than are A and B.
By POE, the answer is E.COMMENTSsd1713 , welcome to SC Butler.
I'm glad to "see" you all. Good explanations get kudos.
