Answer/Explanation:
The following sentences fall under the SUBJECT-VERB AGREEMENT column:
1. "EACH OF THE COMPUTER PARTS [NEEDS] to be parked separately so that everything won't get lost during postal delivery."
=>Rationale: The word "EACH" is singular and agrees with the singular verb [NEEDS] in the sentence.
2. JONATHAN, regardless of how tired he is, always [SPENDS] each morning doing at least 50 push-ups.
=>Rationale: The subject "JONATHAN" is singular, and agrees with the singular verb [NEEDS].
3. "Neither Mattha NOR HER GIRLFRIENDS [ARE] interested in seeing the latest sci-fi movie playing at our local cineplex."
=>Rational: "GIRLFRIENDS" is the part of the compound subject that is closer to the verb, and so determines what form the verb should take. Therefore, "GIRLFRIENDS" attracts the plural verb [ARE]
The following sentences fall under the SUBJECT-VERB DISAGREEMENT column:
1. "ALL OF THE CHEERLEADERS who are on next year's squad [NEEDS] to make sure they've signed the permission forms for the overnight camping trip."
=>Rationale: the subject "ALL OF THE CHEERLEADERS" is plural, and should attract the plural verb "NEED" instead of [NEEDS].
2. "Either the Nelson twins nor DON [ARE] going to have to come over here and feed the Peterson's dog while they are gone."
=>Rationale: "DON" is the closest subject to the verb, and being a singular noun, it does not agree with the plural verb [ARE]. It should rather attract the singular verb "IS".
3. "EVERYONE OF THESE JUNIORS" [NEED] to stay after the prom and help clean up."
=>Rationale: The word "EVERYONE" is singular, and should attract the singular verb "NEEDS" instead of [NEED] as used in the sentence.
