Show Answer Key & Explanations Step-by-step solution for: Which of the following sentences is grammatically correct?
Let's go through each sentence in the worksheet and determine which ones are grammatically correct. We'll analyze each one for subject-verb agreement, proper use of pronouns, punctuation, verb tense, and overall clarity.

---

1. You can either stay and help or leave.


Correct
This sentence is grammatically correct. The structure "either...or" is used properly, and the parallelism is maintained: "stay and help" (two verbs) vs. "leave" (one verb). However, note that "stay and help" is a compound verb phrase, so it’s acceptable.
✔️ Correct

---

2. The doctor gave me pills and they helped.


Incorrect
The issue here is pronoun reference. "They" refers to "pills," but pills cannot "help" in the sense of taking action — it's illogical. The intended meaning might be that *the pills were helpful*, but "they" should refer to something that can act.
Better version: *"The doctor gave me pills, and they were helpful."*
But as written, it's awkward and potentially incorrect due to unclear or illogical reference.
✖️ Incorrect

---

3. We went to the mountains, on our vacation.


⚠️ Debatable – likely incorrect due to comma splice
This sentence has a comma splice. The phrase "on our vacation" is an adverbial phrase that modifies "went," but placing it after a comma like this makes the sentence feel disjointed. It's better to write:
*"We went to the mountains on our vacation."*
Or: *"On our vacation, we went to the mountains."*
As written, it's awkward and not standard.
✖️ Incorrect

---

4. A group of her friends is planning a surprise party for Karen.


Correct
Here, the subject is "A group", which is singular. Even though "friends" is plural, "group" is treated as a collective noun and takes a singular verb.
✔️ Correct

---

5. I don't want no more soup.


Incorrect
This uses a double negative: "don't" and "no" together make the sentence mean "I do want some soup," which is not the intended meaning.
Correct form: *"I don't want any more soup."*
✖️ Incorrect

---

6. The stray cat was adopted by some kind people.


⚠️ Possibly incorrect due to ambiguity
"Kind" could be interpreted as adjective ("nice people") or noun ("a kind of people"). But "some kind people" is not standard. The intended meaning is probably "some kind-hearted people" or "some nice people."
Better: *"The stray cat was adopted by some kind-hearted people."*
As written, it's awkward and may be considered incorrect.
✖️ Incorrect

---

7. Which was the way we wanted it to be.


Incorrect
This is a fragment. It lacks a main verb or complete thought. It's missing context — what is "it"? Also, "which" is not used correctly here; it should be "That was the way..." or "This was the way..."
✖️ Incorrect

---

8. The teacher told Anna to open the window by the door.


Correct
This sentence is clear and grammatically sound. "By the door" indicates location, and the infinitive "to open" is correctly used after "told."
✔️ Correct

---

9. Tom asked, “are you sure you want to go that way?”


Incorrect
The quotation needs capitalization at the beginning. Since it's a direct question, the first word inside the quotation should be capitalized.
Correct: *"Tom asked, 'Are you sure you want to go that way?'"*
✖️ Incorrect

---

10. She was elected Class President.


Correct
This is grammatically correct. "Class President" is capitalized because it's a title used as part of a name or official role.
✔️ Correct

---

1, 4, 8, 10
