Question

one way to punctuate a compound sentence correctly is to join the two independent clauses with

a comma.
a semicolon.
a comma and a subordinating conjunction.
a semicolon and a coordinating conjunction.

Explanation:

Analyze compound sentence structure

A compound sentence contains at least two independent clauses. These clauses can be joined in three main ways:

1. A comma followed by a coordinating conjunction (FANBOYS).
2. A semicolon alone.
3. A semicolon followed by a conjunctive adverb and a comma.

Evaluate the given options

• "a comma": Joining two independent clauses with only a comma creates a comma splice, which is a grammatical error.
• "a semicolon": A semicolon is a correct and complete way to link two closely related independent clauses without any conjunction.
• "a comma and a subordinating conjunction": This combination creates a complex sentence, not a compound sentence.
• "a semicolon and a coordinating conjunction": This is redundant and incorrect punctuation for joining two independent clauses.

Answer:

• a comma.
• a semicolon. (Correct answer)
• a comma and a subordinating conjunction.
• a semicolon and a coordinating conjunction.
