A: Missouri and Illinois are states along the Mississippi River.

1. To determine the correct verb that completes the sentence "Either the mountains of Colorado or the ocean of Florida _____ my next vacation destination," we need to consider subject-verb agreement. In this case, the subject consists of two options: "the mountains of Colorado" and "the ocean of Florida." Since we are only selecting one destination, the subject is singular. Therefore, we need to choose a singular verb that agrees with the subject.

The correct answer is A. "be" - "Either the mountains of Colorado or the ocean of Florida be my next vacation destination."

2. To determine the sentence that exhibits proper subject-verb agreement, we need to make sure that the subject and verb agree in number.

A. "Missouri and Illinois are states along the Mississippi River" - This sentence is correct as both the subject ("Missouri and Illinois") and the verb ("are") are plural.

B. "Neither Harper nor Finn are aware of the details" - This sentence is incorrect. The subject "Neither Harper nor Finn" is singular, but the verb "are" is plural. It should be "Neither Harper nor Finn is aware of the details."

C. "Either you or I are responsible for cleaning the house this afternoon" - This sentence is also incorrect. The subject "Either you or I" is singular, but the verb "are" is plural. It should be "Either you or I am responsible for cleaning the house this afternoon."

D. "Hope, peace, and love is achievable for everyone" - This sentence is incorrect. The subject "Hope, peace, and love" is plural, but the verb "is" is singular. It should be "Hope, peace, and love are achievable for everyone."

Therefore, the sentence with proper subject-verb agreement is A. "Missouri and Illinois are states along the Mississippi River."
