问题     Fourteen-year-old Sean MeCallum lay in a hospital bed waiting for a new heart. Without it, Sean would die. Sean’s case is not unusual. Everyday many people die because there just aren’t enough human organs to go around.
    Now scientists say they can alter the genetic make-up of certain animals so that their organs may be acceptable to humans. With this gene-altering technique to overcome our immune rejection to foreign organs, scientists hope to use pig hearts for transplants by the year 2008.
    That prospect, however, has stirred up strong opposition among animal right activists. They protest that the whole idea of using animal is cruel and unjust. Some scientists also fear such transplants may transmit unknown diseases to humans.
    Others believe transplanting animal organs into humans is unnecessary. Millions of dollars spent on breeding pigs for their organs could be better spent on health education programs. They believe seventy-five percent of the heart disease cases that had lead to a need for organ transplant are preventable. The key is to convince people to eat healthfully, and not to smoke or drink alcohol. Scientists could also use research funds to improve artificial organs.
    Still others believe that though new inventions and prevention programs may help, spending money to encourage more people to donate their organs is an even better idea. If enough people were educated about organ donations, everyone who needed an organ could be taken off the waiting list in a year. [br] Doubtful of the necessity of using animal organs, some scientists______.
选项 A、are to narrow the scope of organ transplants
B、switch to the development of artificial organs
C、come up with alternatives to the current problem
D、set out to purchase better ways of treating heart disease
答案 C
解析 细节题。本题题意是：“一些科学家因为怀疑使用动物器官的必要性，想到了解决目前问题的其他办法。”第三段告诉我们有些科学家认为，没有必要移植动物器官，因为75％的心脏病可以避免，我们不妨把花在研发猪器官移植上的钱用在健康教育上。显然，这一点相较于猪器官移植也是可考虑的解决办法。
