Answer:
C). Sentence 3 should be revised to read, "My next stop will be old Mr. Butterworth's for a ch-at with my favorite neighbor."
Step-by-step explanation:
As per the question, the revision must be made to the third sentence in order to continue the parallel structure as it follows the similar sentence structure of the previous sentences i.e. 'will be' (future tense). The use of the same or repeated grammatical structures in consecutive sentences gives equal significance to every idea and makes it more effective and memorable while adding a flow to it. It also assists in making the ideas easier to understand by adding an order to the ideas. Thus, option C is the correct answer.
