问题 In an experiment conducted last autumn, scientists made exact copies of a human embryo for the first time.
The technique is just used for providing embryos.

选项 A、Right
B、Wrong
C、Not mentioned

答案B

解析 见第五、六段,“But the technique could also be used for other purposes.’通常,医生们要植入多个胚胎以期有一个能着床于子宫。克隆胚胎可给他们提供更多的供植入的胚胎。这项技术也可用于其他目的。
