Question #N927

The passage is about the history of the internet, and the author explains how the internet has changed over time. The author also explains how the internet has impacted society and culture. The author notes that the early internet was a very different place than it is today, but it is clear that the author believes that the internet will continue to evolve and change in the future. What is the most likely reason why the author uses a comma to separate the two clauses "but it is clear...evolve and change"?

In this passage, the comma that follows the clause "but it is clear" is used to
A. separate two independent clauses.
B. separate two dependent clauses.
C. separate an introductory phrase from the main clause.
D. separate a nonessential clause from the main clause.

Correct Answer is: A

The comma that follows the clause "but it is clear" is used to separate two independent clauses. An independent clause is a clause that can stand alone as a complete sentence. The two clauses in this sentence can each stand alone as a complete sentence, so the comma is used correctly to separate them.
