Use what the video says to help you answer the questions. Do not use any other source - everything is answered in the video.

Recommendations -
  • Open question 1 and read it; this will help you know what you are listening for; then play the video and listen for the information related to that question; answer the question; repeat for the next question, etc.
  • It may be helpful for you to listen to the video once before attempting to answer any questions; then re-play it and answer the questions then.
  • Closed captioning is available if needed.

If you are not sure of an answer, rewind the blue cursor to the beginning of that section and replay it.

If the video does not function properly, you may use the original video from YouTube, but you need to read two questions ahead so you know what to listen for, as the video will not pause for you. https://www.youtube.com/watch?v=qBCVVszQQNs&pp=ygUcY2VsbCBtZW1icmFuZSBhbW9lYmEgc2lzdGVycw%3D%3D
