To determine the correct verb forms in these sentences, it's important to identify the subject of each verb.
1. Neither my sister nor my parents (knows, know) the answer to the riddle.
In this sentence, the subject is the compound subject "Neither my sister nor my parents." When you have a compound subject joined by the word "nor," you use the verb form that agrees with the closer subject, which is "my parents." Therefore, the correct verb form is "know."
To get the answer, you can analyze the subject and the word "nor" to identify the correct verb form agreement rule. In this case, the compound subject is "my sister" and "my parents," and the word "nor" means you choose the verb form that agrees with the closer subject.
2. A car and three buses (was, were) involved in the accident.
In this sentence, the subject is the compound subject "a car and three buses." When you have a compound subject joined by the word "and," you use the verb form that agrees with the plural subject. Therefore, the correct verb form is "were."
To get the answer, you can identify the compound subject and the word "and" to determine the correct verb form that agrees with a plural subject. In this case, the compound subject is "a car" and "three buses," and the word "and" indicates that you should use a plural verb form.
