Which choice completes the text so that it conforms to the conventions of Standard English?
Correct Answer: B
Your Answer:
Explanation
B
In this Rules question, punctuation is changing in the answer choices. The first part of the sentence says Sir Paul Maxime Nurse discovered one of these proteins in yeast cells, which is an independent clause. The second part says he was awarded the Nobel Prize in Physiology or Medicine alongside Leland Hartwell and Tim Hunt for identifying a similar protein in human cells, which is also an independent clause. Eliminate any answer that can't correctly connect two independent clauses.
(A) and (D) are wrong because neither a comma alone nor a coordinating conjunction (FANBOYS) alone can connect two independent clauses.
(B) is correct because a comma + a coordinating conjunction (FANBOYS) can connect two independent clauses.
(C) is wrong because it creates a run-on sentence.
