Question 1 answer: The last option
Question 2 answer: Each change of speaker equals a new paragraph.
32 is the amount provided
I would say that all these questions are valid and to the point though perhaps a little less so re the dress. If the speaker is logical, gives sufficient evidence based on solid facts and obviously knows his subject either being an authority on the subject or showing that he/she has closely consulted with those who are, then the speech should be well received.
