- Identify two independent clauses: "America is gripped by an opioid epidemic" and "overdose deaths have risen by 400 percent".
- Recognize that joining these two independent clauses with only a comma creates a comma splice.
- Since no coordinating conjunction is used, the sentence is grammatically classified as a comma splice (CS).
- Final Answer: \(\boxed{CS}\)
Explanation
- Grammatical Analysis of the Sentence
The sentence provided is: "America is gripped by an opioid epidemic, since 2000, overdose deaths have risen by 400 percent."
To determine the classification, we must analyze the structure of the sentence. An independent clause is a complete thought containing a subject and a verb.
- Clause 1: "America is gripped by an opioid epidemic" (Subject: "America", Verb: "is gripped") - This is an independent clause.
- Clause 2: "overdose deaths have risen by 400 percent since 2000" (Subject: "overdose deaths", Verb: "have risen") - This is also an independent clause.
The sentence joins these two independent clauses with only a comma. A comma splice occurs when two independent clauses are joined by only a comma without the use of a coordinating conjunction (such as "and", "but", "or", etc.). Because there is no coordinating conjunction used between the two independent clauses, this construction is a comma splice.
- Classification Decision
Since the sentence consists of two independent clauses connected by a comma without a coordinating conjunction, it is classified as a comma splice. Therefore, the correct label is CS.
Examples
Understanding comma splices is essential for clear writing. For example, if you are writing a report or an essay, using correct punctuation ensures your ideas are distinct and professional. Instead of "The experiment was successful, we gathered the data," which is a comma splice, you would write "The experiment was successful; we gathered the data" or "The experiment was successful, and we gathered the data." These corrections improve the flow and grammatical accuracy of your work.
