Which choice completes the text so that it conforms to the conventions of Standard English?

A

barista; since

B

barista: since

C

barista,

D

barista;

Correct Answer: D

Choice D is the best answer. A semicolon separates two independent clauses ("Brewing... requires precision" and "all the variables...").

Choice A is incorrect because "since" makes the second clause dependent. Choice B is incorrect for the same reason. Choice C is incorrect because it creates a comma splice.
