GROUND CONTROL
GALILEO ONLINE TRAINING

CHAPTER 1 QUIZ

Answers to the questions below are easily found in the chapters the questions were pulled from. For example, Question 1 below refers to the beginning of the video, and question 10 refers to later on in the video. It is the same for the rest of the text chapters. I recommend that you have two web browsers open for taking these quizzes, one for the questions here, and one for the online training materials.
