In some areas of poverty, (including parts of southern Texas) there are no speed limits, rather an indication that you may not go above a certain speed if your car lets off more pollution. Some countries have placed speed limits to limit the consumption of fuel and pollution from any one car. But as I have stated, it's not directly because of the speed, but rather the rate of pollution given off when in that state. :)

Answer:
D). Interference. 
Explanation:
'Interference' in general terms is associated with 'obstructing or intervening in between a particular action or process. In 'speech communication process', it is described as the active or passive obstruction created by the audience that  often leads to break the flow and concentration of the speaker.
As per the question, 'coughing or walking of the audience' in the middle of a presentation would be exemplified as 'interference' because it would distract the speaker as well as other people sitting in the audience and obstruct their attention which may break the flow of ideas collaboratively and coherently. It would also affect their concentration that may <u>influence the readers' understanding(by blocking their capacity to receive the intended message) of the message or idea and therefore, the desired impact would not be evoked.</u> Thus, <u>option D</u> is the correct answer.
