1. A _____ occurs when two or more complete sentences are connected improperly.

Options:
A) Chili cook off
B) Fragment
C) Run-on

✔ Correct Answer: C) Run-on

Explanation:
A run-on sentence happens when two or more independent clauses (complete sentences) are joined without proper punctuation or conjunctions. For example: "I went to the store I bought milk." This is a run-on.
- A fragment is an incomplete sentence (missing subject, verb, or idea).
- "Chili cook off" is unrelated and not a grammar term.

2. Judy leads a charmed life she never seems to have a serious accident.

Options:
A) No Change
B) life; she
C) life, yet
D) life, she

✔ Correct Answer: C) life, yet

Explanation:
The original sentence is a run-on: two independent clauses joined without proper punctuation.
- "Judy leads a charmed life" and "she never seems to have a serious accident" are both complete sentences.
- To fix it, we need either a semicolon, a coordinating conjunction, or a comma with a conjunction.
- Option C uses a comma and the conjunction "yet", which correctly connects the ideas:
→ "Judy leads a charmed life, yet she never seems to have a serious accident."

Option B ("life; she") is incorrect because a semicolon cannot be followed by a subject without a verb in this context.
Option D ("life, she") lacks a conjunction and creates a comma splice.

3. The results of the study were inconclusive, therefore more research needs to be done on the topic.

Options:
A) No Change
B) inconclusive, therefore,
C) inconclusive, but therefore
D) inconclusive; therefore,

✔ Correct Answer: D) inconclusive; therefore,

Explanation:
"Therefore" is a conjunctive adverb, and it should be preceded by a semicolon and followed by a comma when connecting two independent clauses.
- Original: "The results... were inconclusive, therefore more research..." → This is a comma splice (two independent clauses joined only by a comma).
- Correct form: Use a semicolon before "therefore" and a comma after.
- So: "The results of the study were inconclusive; therefore, more research needs to be done..."

Option B adds extra commas incorrectly. Option C uses "but therefore", which is awkward and redundant. Option A keeps the comma splice.

4. What's the best way to fix this sentence: John wants pizza and Kate wants a banana.

Options:
A) John want's pizza and Kate want's a banana.
B) John and Kate wants pizza and a banana.
C) John wants pizza and Kate; she wants a banana.
D) John wants pizza, and Kate wants a banana.

✔ Correct Answer: D) John wants pizza, and Kate wants a banana.

Explanation:
The original sentence is a run-on — two independent clauses joined by just "and". It needs proper punctuation.
- Option A has incorrect verb forms ("want's" instead of "wants").
- Option B has subject-verb agreement error: "John and Kate" is plural → "want", not "wants".
- Option C is confusing and grammatically incorrect: "Kate; she wants..." — semicolon used improperly.
- Option D correctly uses a comma + coordinating conjunction (and) to join the two independent clauses.

So, the correct answer is D.

5. Which is the correct punctuation of the sentence?

Image shows a dog, but the sentence is:

"I have a dog; he barks constantly."

Options:
A) I have a dog; he barks constantly.
B) I have a dog; He barks constantly.
C) I have a dog, he barks constantly.

✔ Correct Answer: A) I have a dog; he barks constantly.

Explanation:
This sentence contains two independent clauses:
- "I have a dog"
- "He barks constantly"

They can be joined with a semicolon because they are closely related ideas.
- Option A is correct: Semicolon between two independent clauses — proper usage.
- Option B has a capital "H" after the semicolon — incorrect. After a semicolon, you don't capitalize unless it's a proper noun.
- Option C uses a comma splice — joining two independent clauses with only a comma, which is a grammatical error.

1. C) Run-on
2. C) life, yet
3. D) inconclusive; therefore,
4. D) John wants pizza, and Kate wants a banana.
