The given pattern is D because the first line and third line don't rhyme, while the second and fourth do. This is regarding each stanza of the poem.
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!
C wouldn’t be the answer neither would A or D they are not well supported and I would choose a if I were you so I hope this helped
It helps show how the bat can make many things
