Correcting subject-verb agreement errors in sentences.

Let's go through each sentence and determine the correct verb form based on subject-verb agreement. The key here is identifying whether the subject is singular or plural, especially when dealing with collective nouns, indefinite pronouns, or phrases like "each of," "none of," "some of," etc.

1. Everyone on the team support/supports the coach.

- Subject: "Everyone" — this is a singular indefinite pronoun (meaning "every person").
- Even though "team" is plural, "everyone" refers to individuals, so it takes a singular verb.
- ✔ Correct answer: supports

> ✔️ Everyone on the team supports the coach.

---

2. Many of my favorite stories is/are by Hemingway.

- Subject: "Many of my favorite stories" — "many" is plural, so the verb must be plural.
- ✔ Correct answer: are

> ✔️ Many of my favorite stories are by Hemingway.

---

3. Each of the furrows has/have been seeded.

- Subject: "Each of the furrows" — "each" is singular, even though it refers to multiple furrows.
- So we use a singular verb.
- ✔ Correct answer: has

> ✔️ Each of the furrows has been seeded.

---

4. Nobody who participated in the clinical trials was/were given a placebo.

- Subject: "Nobody" — this is a singular indefinite pronoun (meaning "not a single person").
- It takes a singular verb, regardless of the clause that follows ("who participated...").
- ✔ Correct answer: was

> ✔️ Nobody who participated in the clinical trials was given a placebo.

5. Few of the students was/were able to stay after school.

- Subject: "Few of the students" — "few" means "a small number," which is plural.
- So the verb must be plural.
- ✔ Correct answer: were

> ✔️ Few of the students were able to stay after school.

---

6. None of his advice make/makes sense.

- Subject: "None of his advice" — "advice" is an uncountable noun, and "none" can be singular or plural depending on context.
- But when "none" refers to an uncountable noun (like "advice"), it's treated as singular.
- Also, "makes sense" is idiomatic and typically used with a singular verb.
- ✔ Correct answer: makes

> ✔️ None of his advice makes sense.

---

7. Some of the rocks was/were slippery.

- Subject: "Some of the rocks" — "rocks" is plural, so "some" refers to a plural noun.
- Therefore, the verb should be plural.
- ✔ Correct answer: were

> ✔️ Some of the rocks were slippery.

---

8. None of the eggs was/were broken.

- Subject: "None of the eggs" — "eggs" is plural, and "none" here refers to a countable plural noun.
- In modern English, "none" often takes a plural verb when referring to plural nouns, especially in formal writing.
- However, both "was" and "were" can be acceptable, but "were" is more natural here.
- ✔ Best choice: were

> ✔️ None of the eggs were broken.

*(Note: Some traditional grammar rules say "none" is always singular, but in practice, when "none" refers to plural nouns, plural verbs are commonly accepted and preferred.)*

9. Some of our luggage was/were lost.

- Subject: "Some of our luggage" — "luggage" is an uncountable noun.

> ✔️ Some of our luggage was lost.
