21. Naturalist： For decades we have known that the tuatara, a New Zealand reptile, has been approaching extinction on the South Island. But since South Island tuatara were thought to be of the same species as North Island tuatara there was no need to protect them. But new research indicates that the South Island tuatara are a distinct species, found only in that location. Because it is now known that if the South Island tuatara are lost an entire species will thereby be lost, human beings are now obliged to prevent their extinction, even if it means killing many of their unendangered natural predators.　　Which one of the following principles most helps to justify the naturalists' argumentation？
　　（A） In order to maximize the number of living things on Earth. Steps should be taken to preserve all local populations of animals.
　　（B） When an animal is in danger of dying, there is an obligation to help save its life, if doing so would not interfere with the health or well-being of other animals or people.
　　（C） The threat of local extinction imposes no obligation to try to prevent that extinction, whereas the threat of global extinction does impose such an obligation.
　　（D） Human activities that either intentionally or unintentionally threaten the survival of an animal species ought to be curtailed.
　　（E） Species that are found in only one circumscribed geographical region ought to be given more care and attention than are other species because they are more vulnerable to extinction.
　　22. Nursing schools cannot attract a greater number of able applicants than they currently do unless the problems of low wages and high-tress working conditions in the nursing profession are solved. If the pool of able applicants to nursing school does not increase beyond the current level, either the profession will have to lower its entrance standards, or there will soon be an acute shortage of nurses. It is not certain, however, that lowering entrance standards will avert a shortage. It is clear that with either a shortage of nurses or lowered entrance standards of the profession, the current high quality of health care cannot be maintained.

　　（B） The nursing profession will have to lower its entrance standards if the pool of able applicants to nursing school does not increase beyond the current level.
　　（C） If the nursing profession solves the problems of low wages and high-stress working conditions, high quality health care will be maintained.
　　（D） If the nursing profession fails to solve the problems of low wages and high-stress working conditions, there will soon be an acute shortage of nurses.
　　（E） The current high quality of health care will not be maintained if the problems of low wages and high-stress working conditions in the nursing profession are no solved.
