Understanding Subject-Verb Agreement
The question asks us to select the most appropriate option to substitute the underlined segment "has been" in the sentence: "The details of the menu for today's party has been worked out." This involves checking for correct subject-verb agreement.
Identifying the Subject and Verb
To find the subject of the verb, we need to identify what the verb is referring to. In the sentence, the verb phrase is "has been worked out". This verb phrase describes something that has been worked out.
Let's look at the sentence structure:
- "The details" is the main noun phrase.
- "of the menu" is a prepositional phrase modifying "details".
- "for today's party" is another prepositional phrase modifying "menu".
- The subject of the sentence is the noun phrase that the verb agrees with. In this case, the subject is "details".
The noun "details" is a plural noun. The verb must agree in number with its subject.
Analyzing the Underlined Segment: "has been"
The underlined verb phrase is "has been worked out". The auxiliary verb here is "has been". The verb "has" is the third-person singular form of "to have" in the present perfect tense. Since the subject "details" is plural, the singular verb "has" does not agree with it.
Evaluating the Options for Correct Subject-Verb Agreement
We need to find a verb phrase that agrees with the plural subject "details" and fits the context of the sentence.
Let's examine each option:
- No substitution required: This option would be correct if the original sentence had no grammatical errors. However, as identified, the subject "details" is plural, and the verb "has been" is singular. Therefore, a substitution is required to correct the subject-verb agreement error.
- have been: The auxiliary verb "have" is the third-person plural form of "to have" in the present perfect tense. The phrase "have been worked out" is the present perfect passive form. This verb phrase agrees with the plural subject "details" and makes grammatical sense in the sentence.
- are been: This combination is grammatically incorrect in standard English. "Are" is a form of "to be", and "been" is the past participle of "to be". They are not typically used together in this structure. The correct passive structure in the present tense would be "are worked out", or in the present perfect passive "have been worked out".
- is being: The phrase "is being worked out" is the present continuous passive form. This verb phrase uses the singular auxiliary "is", which does not agree with the plural subject "details". Also, the present continuous passive ("is being worked out") implies an action happening right now, whereas the original sentence's context ("has been worked out") suggests a completed action, or an action completed in the recent past with relevance to the present.
Conclusion on Subject-Verb Agreement
Based on the analysis, the only option that provides the correct subject-verb agreement for the plural subject "details" and fits the grammatical structure and likely meaning of the sentence is "have been". The complete correct sentence would be: "The details of the menu for today's party have been worked out."

Revision Table: Key Grammar Concepts
| Concept | Explanation | Example (Correct) |
|---|---|---|
| Subject-Verb Agreement | The verb in a sentence must agree in number (singular or plural) with its subject. | The book is on the table. The books are on the table. |
| Identifying the True Subject | Prepositional phrases (like "of the menu", "for the party") often come between the subject and the verb, but they do not affect the verb's agreement. The verb agrees with the main subject noun. | The color of the cars is red. (Subject is "color", not "cars") |
| Passive Voice (Present Perfect) | Formed with "have/has been" + past participle. Used for actions completed in the past with results in the present, where the focus is on the action or recipient, not the doer. | The report has been finished. (Singular subject "report") The reports have been finished. (Plural subject "reports") |
Additional Information on Subject-Verb Agreement
Subject-verb agreement is a fundamental rule in English grammar. It ensures that your sentences are grammatically correct and clear. Errors in subject-verb agreement can make your writing sound awkward or confusing.
Here are some points to remember about subject-verb agreement:
- Singular subjects take singular verbs (usually ending in -s in the present tense for third person).
- Plural subjects take plural verbs (usually without -s in the present tense).
- Phrases or clauses between the subject and the verb do not change the subject's number. Identify the core subject noun.
- Some words, like "each," "every," "either," "neither," "one," "nobody," "somebody," etc., are singular and take a singular verb, even if followed by a plural phrase (e.g., "Each of the students is here.").
- Words like "both," "few," "many," "several" are always plural.
- Collective nouns (like team, committee, family) can be treated as singular or plural depending on whether the group acts as a single unit or as individuals.
Paying attention to the true subject of the sentence, especially when it is separated from the verb by other phrases, is key to mastering subject-verb agreement.
