问题     There is a growing concern throughout the world that the use of stem-cell research, the process whereby certain cells are extracted from fetuses for future cloning purposes, may lead to a moral dilemma on the nature of cloning technology.
    Indeed, certain professionals in the field of cloning will likely face a difficult moral choice in the near future. Embryonic cells are currently extracted from aborted fetuses and then used to generate organs that replace missing or diseased ones in humans. The potential for such swapping of injured or missing limbs is enormous. Amputated arms and diseased livers could be replaced by newly cloned ones by adapting such embryonic cells. However, certain anti-abortion groups have already decried the use of aborted fetuses and pledged to boycott any more such research.
    In the United States, President Bush recently signed an executive order banning the use of any Federal money for the purpose of human cloning. However, many political observers note that private research into human cloning continues unabatedly and that, even if the United States supported and managed to enforce an outright ban in both the public and private sectors, competition from other countries would put pressure on US firms to develop their own cloning technology.
    A new option has recently been developed to weaken opposition to cloning efforts. New research has uncovered the use of similar stem-cells in fat tissue. The use of such tissue is not as politically volatile since it avoids the issue of abortion. Moreover, proponents of such cloning technology often cite the enormous benefits to medical science that reproductive cloning could reap. Cloning technology could finally cure certain diseases and ailments that are currently untreatable.
    However, the prospect of playing god with human genetics has made many weary of pursuing human or partial human cloning. As the successful cloning of Dolly the sheep proved, human cloning may only be a few decades away. For many, the ethical and legal consequences of responding to new technologies that advance the field of cloning have been difficult. Can governments, citizens and private groups come to a consensus on the use and limitations of cloning? Or will we end up with a new generation of monsters, spawned from our desire for eternal life?
The author refers to a potential new generation of monsters to______.
选项 A、refer to the potential dangers of cloning humans
B、make reference to a popular novel that supports cloning
C、denounce cloning technology
D、support the use of stem-cell technology
答案A
解析 属概念推断题。题目中的关键词new generation of monsters出现在文章最后一句：难道我们因为想获得永生而最终不惜催生出新一代的怪物来吗?从本句所在的上下文来看，它是对本段第三句的举例说明：推进克隆技术的每一步所产生的道德和法律后果都是很严重的。由此可知，选项A正确(指克隆人存在的潜在危险)。其他选项都推理有误。
