Question

What is the BEST way to combine the information in the two sentences below?

Answer 1

A. Mercedes threw Andrea, Mercedes’ best friend, a surprise birthday party last night would makes there most sense.

Answer 2

The answer is A. Mercedes threw Andrea, Mercedes' best friend, a surprise party last night.  This choice uses an appositive ("Andrea, Mercedes' best friend,") to combine the two sentences.  An appositive is a phrase separated from the rest of the sentence by commas that describes something (in this case Andrea).

Choices B and C are incorrect because the uses of the words "but" and "when" to combine the sentences do not make logical sense.  Choice D is incorrect because it uses a comma to combine the sentences without a conjunction, creating a run-on sentence.

Hope this helps!
