Question #N32

After years of research, a scientist announced the discovery of a new species of butterfly, one that was previously unknown to science. The scientist, who had devoted years to the study of butterflies, was thrilled with the discovery, and the team of researchers that assisted her in the project were equally excited about the finding. "This butterfly is the most interesting one I've ever seen!" the scientist exclaimed. "It has a unique wing pattern that I have never seen before. I believe it’s a new species, and I can’t wait to learn more about it."

Which choice best revises the sentence to make it conform to the conventions of Standard English?
A. This butterfly is the most interesting one I've ever seen, and I can’t wait to learn more about it.
B. This butterfly is the most interesting one I've ever seen. I can’t wait to learn more about it.
C. This butterfly is the most interesting one I've ever seen; I can’t wait to learn more about it.
D. This butterfly is the most interesting one I've ever seen, and I can’t wait to learn more about it.

Correct Answer is: B

The original sentence contains a comma splice, a common error in which a comma is used to connect two independent clauses without a conjunction. The correct way to fix this is to replace the comma with a period or a semicolon. Of the choices given, only choice B correctly uses a period to connect the two independent clauses.
