4) A survey is like a quiz with multiple choices for answers to each question. To answer a survey, respond to each numbered question with the marked letter representing your choice of answers. If you do not select a lettered answer, then you will not receive credit for answering the question. After you complete the survey, your answers will be checked by the teacher, and the correct answers will be given. If you selected all the correct answers, you will be deemed eligible to enter in a sweepstakes to potentially win a $100 gift card as a reward for participating in the survey. In targeted advertising and government surveillance, these surveys are used to monitor people's thinking and track their opinions, and control their behavior with subliminal messaging.
