正确答案:B
细节题。第三段首先提到,多利的诞生以及威尔穆特成功克隆了一只成年的母羊,之后提到这样做产生的后果,即美国科学家被立刻传唤到政客面前,他们对于人可能会被克隆的潜在影响感到不安。对科学进步速度的忧虑使得美国政府停止了对诸如试管受精等有争议性领域的科研资助,故[B]为正确答案,同时可知,[A]是对此句的曲解和无根据的引申,故排除。[C]“美国大学开始在海外进行类似的研究”文中未提及,故排除;根据本段最后一句提到的(美国政府对试管受精研究资助的暂停)并没有使该研究停滞;相反的是,试管受精:亡业在私营经济领域繁荣起来,而急切想要孩子的夫妇们和看到新市场有利可图的投资者为其提供了资金,由此可知,[D]的陈述与原文不符,故排除。
