问题 The writer holds that the potential to make healthy body tissues will ______.
The word "rejuvenated" (Line 3, Para. 5) most probably means ______.

选项 A、modified
B、re-collected
C、classified
D、reactivated

答案D

解析词义推测题。该句前面一句说，重新激发一个成熟细胞中的基因组、将其发展指令重设为初始状态；此句则指代前面经过处理的细胞说，这种______细胞可以发育成为成熟的动物。由两句之间的逻辑可知，rejuvenated应当与前一句中的reactivating意思相同。
