问题 A. the nucleus of a cell
B. cloned human beings
C. a human being in two years
D. a law to ban human cloning
E. a report on human cloning
F. heavy media coverage
Richard Seed claimed to be able to clone______.

选项

答案C

解析 文中有两个地方提到Richard Seed,分别是在第一段和第二段,该题题干大意为:Richard Seed宣称他能克隆——。据此可将原文定位至第一段最后一句…when Chicago physicist Richard Seed made a surprising announcement。“We will havemanaged to clone a human being within the next two years,”he told the world.由此可推断,需要添加的部分即为旬中画线部分,显然C为正确答案。
