ANON, the sentence wasn't finished... please retype.

To determine if the given sentence is correct, we need to focus on the grammar area specified, which in this case is "Vague pronouns." Vague pronouns refer to pronouns that lack clear antecedents, making it unclear who or what the pronoun is referring to.

Now, let's examine the sentences provided:
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..."

Based on the information provided, we can see that the sentence 25b is incomplete. It lacks a continuation or an appropriate reference point in relation to air pollution and population growth. Therefore, sentence 25a is the correct sentence.

However, please note that without the complete context of the exercise or further information about the specific focus on vague pronouns, it may be difficult to provide a definitive answer.
