C?

Can you explain why?

anonymous · Answer

because if you switch it around to make it looklike As a matter of fact at the beggining you would have to breath before you say the rest of the sentence

Interesting explanation, however, I do agree that C is correct...

My explanation:
A is incorrect, because it needs a pause after "ensembles".

B is incorrect, because the pause needs to be applied after "speaking", and needs no commas after.

C is correct because it uses pauses correctly.

D is incorrect, because there is no pause or comma needed after "way".
