The security system at the vault allows the manager to ___________ denies access to everyone else.
Which choice completes the text so that it conforms to the conventions of Standard English?
enter: but
enter; however, it
enter: however, it
enter; but
Correct Answer: B
Choice B is the best answer. A semicolon separates two independent clauses, and the transition word "however" is followed by a comma.
Choice A is incorrect because a colon is not used with "but" in this manner. Choice C is incorrect because a colon is not used before a transition word like "however" when separating clauses. Choice D is incorrect because a semicolon is typically used between independent clauses, not before a coordinating conjunction like "but."
