Harvard professor Harvey Mansfield stirred up controversy recently by criticizing the violent grade inflation at his institution, stating, "I was told that the most frequently given grade at Harvard right now is an A-." A recent【C1】______of 200 colleges and universities also found that more than 40 percent of all grades awarded were in the A range. Some argue that these inflated grades are【C2】______for the competitive job market, but at the national level it is a negative-sum game that【C3】______serious costs on society. Because grades are【C4】______at A or A+, grade inflation results in a greater concentration of students at the【C5】______of the distribution. This【C6】______of grades diminishes their value as a(n) 【C7】______of student abilities. There is also evidence that【C8】______grading reduces student effort. As giving low grades puts students at a disadvantage【C9】______to their peers, professors face strong 【C10】______ to award inflated grades. 【C11】______universities need to take steps to bring it under【C12】______. Recently, some universities have experimented with【C13】______ information about the grade distribution for each course either online or on student transcripts. So, if employers are aware that grades in a particular course were high, they might be less 【C14】______with the students who earned those grades. Thus, students might seek out tougher courses, 【C15】______professors to offer such courses in 【C16】______. The administration of Princeton issued a【C17】______that no more than 35 percent of grades awarded in undergraduate courses should be in the A range. These steps may not be【C18】______with students and professors, but it"s necessary to prevent higher education from【C19】______into Lake Wobegon—"where... all the children are above【C20】______." 【C12】

A. consideration

Euthanasia is clearly a deliberate and intentional aspect of a killing. Taking a human life, even with subtle rites and consent of the party involved is barbaric. No one can justly kill another human being. Just as it is wrong for a serial killer to murder, it is wrong for a physician to do so as well, no matter what the motive for doing so may be. Many thinkers, including almost all orthodox Catholics, believe that euthanasia is immoral. They oppose killing patients in any circumstances whatever. However, they think it is all right, in some special circumstances, to allow patients to die by withholding treatment. The American Medical Association"s policy statement on mercy killing supports this traditional view. In my paper "Active and Passive Euthanasia" I argue, against the traditional view, that there is in fact no normal difference between killing and letting die—if one is permissible, then so is the other. Professor Sullivan does not dispute my argument; instead he dismisses it as irrelevant. The traditional doctrine, he says, does not appeal to or depend on the distinction between killing and letting die. Therefore, arguments against that distinction "leave the traditional position untouched". Is my argument really irrelevant I don"t see how it can be. As Sullivan himself points out, nearly everyone holds that it is sometimes meaningless to prolong the process of dying and that in those cases it is morally permissible to let a patient die even though a few more hours or days could be saved by procedures that would also increase the agonies of the dying. But if it is impossible to defend a general distinction between letting people die and acting to terminate their lives directly, then it would seem that active euthanasia also may be morally permissible. But traditionalists like Professor Sullivan hold that active euthanasia—the direct killing of patients—is not morally permissible; so, if my argument is sound, their view must be mistaken. I can not agree, then, that my argument "leave the traditional position untouched". However, I shall not press this point. Instead I shall present some further arguments against the traditional position, concentrating on those elements of the position which professor Sullivan himself thinks most important. According to him, what is important is, first, that we should never intentionally terminate the life of a patient, either by action or omission, and second, that we may cease or omit treatment of a patient, knowing that this will result in death, only if the means of treatment involved are extraordinary. Which of the following is TRUE according to the passage

A. Euthanasia is a term whose meanings are too subtle to be definite.
B. Sullivan contends that there is difference between killing and letting die.
C. Modern medicine has assisted terminally ill patients in painless recovery.
D. The author doesn"t agree that he left the traditional position untouched.
