ANSWER KEY & EXPLANATIONS
1 (b)
Explanation: A period (.) is needed to separate two independent sentences. Option (a) is a common mistake called a “comma splice” (using a comma to join two full sentences). Option (c) is a run-on sentence with no punctuation.
2 (c)
Explanation: We must use a period to end the first sentence and a capital letter to start the next one. Option (a) fails to capitalize the first letter of the new sentence. Option (b) is a comma splice.
3 (a)
Explanation: Both parts are complete sentences. They must be separated by a period, and “It” must be capitalized. Option (c) is a comma splice, and (b) lacks the capital letter.
4 (b)
Explanation: Option (b) correctly uses a period and a capital letter for the imperative sentence “Don’t be late.” Option (c) is a comma splice, and (a) is a run-on error.
5 (c)
Explanation: The first clause is a statement, not a question, so it ends with a period. Option (a) incorrectly uses a question mark. Option (b) is a comma splice.
6 (b)
Explanation: “Our room is unavailable” and “We need to move…” are complete thoughts. Option (a) is a comma splice. Option (c) uses a lowercase letter after a period, which is grammatically incorrect.
7 (a)
Explanation: The pronoun “I” must always be capitalized, especially at the beginning of a sentence. Option (b) is a comma splice. Option (c) uses a lowercase “i”.
8 (b)
Explanation: Option (b) correctly separates the sentences. Option (c) incorrectly uses a comma to link two independent clauses. Option (a) leaves out punctuation entirely.
9 (c)
Explanation: Option (c) provides the necessary period and capitalization. Option (a) is the common comma splice error. Option (b) creates a confusing run-on sentence.
10 (b)
Explanation: You need a period and a capital letter to start the new sentence “We will use…”. Option (a) uses a lowercase “w”, and (c) is a comma splice.
11 (a)
Explanation: Option (a) correctly separates the actions. Option (c) is a comma splice. Option (b) provides no punctuation, causing the sentences to crash into each other.
12 (c)
Explanation: A period followed by a capital letter is the standard way to separate these two facts. Option (a) is a comma splice, and (b) forgets the capital letter.
13 (b)
Explanation: Option (b) properly separates the cause and the effect into two clean sentences. Option (c) uses a comma incorrectly. Option (a) lacks capitalization.
14 (c)
Explanation: “I am waiting outside the library” is a statement, and “Come and find me” is an imperative sentence. They must be separated by a period. Option (a) is a comma splice. Option (b) is a run-on.
15 (a)
Explanation: Option (a) correctly separates the negative imperative from the statement. Option (b) is a comma splice. Option (c) fails to capitalize “It”.
16 (b)
Explanation: Option (b) properly divides the two sentences. Option (c) is the classic comma splice error. Option (a) is a run-on.
17 (c)
Explanation: “Are you near the campus?” is a direct question and requires a question mark. “We are in the cafeteria right now” is a new sentence. Options (a) and (b) fail to recognize the question format.
18 (c)
Explanation: Option (c) correctly ends the first statement with a period and starts the second with a capital letter. Option (b) is a comma splice. Option (a) has a capitalization error.
19 (a)
Explanation: Option (a) is correct. Option (c) is a comma splice. Option (b) blends the two sentences together without any punctuation, making it hard to read.

Explanation: Option (b) uses a period and capitalization correctly. Option (a) is a comma splice. Option (c) is a run-on error.
GRAMMAR POINTS TO REMEMBER
- Independent Sentences: An independent sentence (or clause) contains a subject and a verb and expresses a complete thought (e.g., “The classroom is closed.”).
- The Comma Splice Trap: A very common mistake is using a comma (,) to connect two independent sentences (e.g., “The classroom is closed, we will study in the library.”). This is grammatically incorrect in English.
- The Golden Rule: Always separate two independent sentences with a period (.), and always start the new sentence with a Capital Letter. (e.g., “The classroom is closed. We will study in the library.”)
- Questions: If the first sentence is asking something, replace the period with a question mark (?), but you still must capitalize the first letter of the following sentence. (e.g., “Are you there? We are waiting.”)
