Yes. If an argumentative person brings up a point that's later in the agenda, make sure they know that you will answer that later on in the meeting.
Either C or D but I think D is correct.
If you receive a 1 on the ideas and content rubric, it may mean that : the severity and the frequency of errors are so overwhelming that the readers find it difficult to focus on the message. You might want to try a little bit harder if you only receive a 1.
hope this helps
