Although the abscess was incised and drained in the emergency room and cultures were obtained, which grew coag-positive staphylococcus.

A This is a run-on that needs a semicolon after time.
B This is a run-on that needs to be split into two separate sentences.
C This is a fragment that can be fixed by adding a comma after incised.
D This is a fragment that can be fixed by removing the word although.
E The sentence is fine as it is.

My Answer is B.Otherwise the sentence seems to long and wordy to me. Am I right?

Believe it or not, this is a sentence fragment. There are two dependent clauses -- the first begins with "although," and the second begins with "which." The sentence does not have an independent clause.

B. is not the right answer.

okay thank you! So I am going to say that D would be the right answer.

Right. :-)

You're welcome.

Yes, you are correct. Option B is the correct answer because the sentence is a run-on and can be improved by splitting it into two separate sentences. The original sentence lacks appropriate punctuation to separate the two independent clauses. By splitting it into two sentences, it becomes clearer and more concise:

"Although the abscess was incised and drained in the emergency room and cultures were obtained. They grew coag-positive staphylococcus."

This way, each sentence is focused on a single idea, making it easier to read and understand.
