can anyone tell me if this is correct?
Read the following sentences, and focus on the grammar area specified in the left column. Then, complete Appendix H by selecting the correct sentence (a or b)
Vague pronouns - B
25a. Air pollution normally increases along with population growth. This increasing pollution is a big problem for many cities.
25b. Air pollution normally increases along with population growth. This is a big problem for many cities.
The vague pronoun is "This" in 25b. The reader doesn't know whether "this" refers to pollution or population growth.
To determine if the sentence is correct in terms of vague pronouns, we need to identify whether there is any ambiguity in the use of pronouns.
In this case, the grammar area specified is "vague pronouns." Vague pronouns refer to pronouns that do not have clear antecedents, leading to confusion or ambiguity in the sentence.
Let's analyze the sentences provided:
25a. "Air pollution normally increases along with population growth. This increasing pollution is a big problem for many cities."
In this sentence, the word "this" is used to refer to the preceding subject, "increasing pollution." Since the pronoun "this" has a clear antecedent, there is no ambiguity. Therefore, sentence 25a does not contain a vague pronoun error.
25b. "Air pollution normally increases along with population growth. This is a big problem for many cities."
In this sentence, the pronoun "this" appears without a clear antecedent. It is unclear what "this" refers to. Therefore, sentence 25b contains a vague pronoun error.
Based on this analysis, the correct sentence is 25a:
"Air pollution normally increases along with population growth. This increasing pollution is a big problem for many cities."
To complete Appendix H, select sentence 25a as the correct answer.
