问题 Identical twin sisters have led British scientists to a breakthrough in leukemia research that promises more effective therapies with fewer harmful side-effects.

选项 A、administers
B、nurtures
C、inspires

答案D

解析 题意:双胞胎姐妹让英国科学家在白血病研究上有了突破,能使治疗方案效果更好,副作用更少。划线单词promise的意思足“承诺,保证”,与ensure含义相同。administer“管理”;nurture“培育”; inspire“鼓励”。故选D。
