Answer:
a. July 13, 2012
b. The date, by the way, is the anniversary of the day they met.

a. A comma is normally inserted after Month, date and right before the year.
b. 'By the way' is a filler phrase that requires two commas before and after.
The correct answer is A. We practiced for the debate and many arguments were rehearsed.
As you can see in this sentence, in the first part the pronoun <em>we </em>is used, and in the latter part, that pronoun just disappears and the sentence suddenly becomes passive rather than active. The shift isn't done properly - it is rather awkward. The other options are consistent - they use only one voice rather than two (like in sentence A).
I think the first one is the enwrapped one
