OE
Although Prince Edward Island is the smallest of the Canadian provinces, there is a robust agricultural industry in which they produce one quarter of Canada’s potatoes.
(A) there is a robust agricultural industry in which they produce
The pronoun “they” does not have a logical antecedent. The only plural noun to which “they” could refer is “provinces,” but from the context “Although Prince Edward Island is the smallest of the Canadian provinces,” we can see that the logical meaning is that Prince Edward Island in particular, not all of the provinces, produces one quarter of Canada’s potatoes. Of course, the plural pronoun “they” cannot refer to the singular noun “Prince Edward Island.”
Additionally, “there is a robust agricultural industry” conveys a vague meaning because “there is” simply conveys that “a robust agricultural industry” exists in general but does not link that industry to Prince Edward Island specifically.
(B) the agricultural industry of that is robust, producing
It’s unclear to what “that” refers in “the agricultural industry of that is robust.” This version is a good example of a sentence in which the use of a personal pronoun, rather than a demonstrative pronoun, would clarify the meaning.
Since no comparison is expressed by the sentence, the use of the demonstrative pronoun does not make sense. In other words, although we may assume that “that” refers to “Prince Edward Island,” in this context, “that” could be anything. In this case, the personal pronoun “it” would directly refer to the singular noun “Prince Edward Island,” conveying a clear and logical meaning.
(C) that has a robust agricultural industry that produces
It’s unclear to what “that” refers in “that has a robust agricultural industry.” This version is a good example of a sentence in which the use of a personal pronoun, rather than a demonstrative pronoun, would clarify the meaning.
Since no comparison is expressed by the sentence, the use of the demonstrative pronoun does not make sense. In other words, although we may assume that “that” refers to “Prince Edward Island,” in this context, “that” could be anything. In this case, the personal pronoun “it” would directly refer to the singular noun “Prince Edward Island,” conveying a clear and logical meaning.
(D) its agricultural industry is robust, producing
This version uses the possessive personal pronoun “its” to directly refer to the singular noun “Prince Edward Island,” conveying a clear and logical meaning.
In fact, this is the only version that uses a personal pronoun to refer directly to the subject “Prince Edward Island.”
Notice that there is no other singular noun to which “its” could possibly refer.
The meaning is unambiguous, and the sentence contains no grammatical errors.
Correct Answer
(E) this has a robust agricultural industry, which produces
It’s unclear to what “this” refers in “this has a robust agricultural industry.” Notice that the sentence does not use “this” as a demonstrative adjective to specify that “this island has a robust agricultural industry.” Doing so would convey a clearer meaning.
As the sentence stands, although we may assume that “this” refers to “Prince Edward Island,” in fact “this” could be anything because “this” is not pointing out a specific noun in this context.
Notice that this choice is essentially the same grammatically as the incorrect choice (C). In other words, “that has” and “this has” are no different in this context; they are two versions of the same error. [Notice also that “industry that produces” in choice (C) and “industry, which produces” here also are simply two (in this case, valid) ways to say the same thing, that the industry produces the potatoes.]
