a) Is the cell phone changing our views about polite and impolite behaviour? For example, is it polite for someone to be talking on their cell phone while ordering a drink at Starbucks? Zaidi says, "When I'm trying to face-to-face conversation with someone, and that person repeatedly interrupts the conversation to answer their cell phone or exchange text messages, they are basically telling me that I'm not worth all of their attention." Do you agree with Zaidi? Defend your answer from an ethical point of view when dealing with people. (10 marks) b) Students in a history class are asked to take quiz posted on the course website. The instructor has explained the following rules to the students: First, they are supposed to do their own work. Second, they are free to consult their lecture notes and textbook while taking the quiz. Third, in order to get credit for the quiz, they must correctly answer at least 80 percent of the questions. If they do not get a score of 80 percent, they may take the quiz as many times as they wish. Mary and John are both taking the quiz. They are sitting next to each other in the computer room. John asks Mary for help in answering one of the questions. He says, "What's the difference if you tell me the answer, I look it up in the book, or I find out from the computer that my answer is wrong and retake the quiz? In any chance, I'll end up getting credit for the right answer." Mary tells John the correct answer to the question. Examine the morality of Mary's decision. (15 marks)
