问题 One virus strain that may help gene therapists cure genetic brain diseases can enter the peripheral nervous system and travel to the brain, ______ the need to inject the therapeutic virus directly into the brain.
选项 A、suggesting
B、intensifying
C、elucidating
D、satisfying
E、obviating
答案E
解析 - 方程等号：逗号说明前后句意同义重复。
- 强词和对应：根据题意，前文说一类可以帮助基因治疗专家治愈遗传性脑部疾病的病毒可以进入周围神经系统并且抵达至大脑，后文提到一种将有助于治疗的病毒直接注入大脑中的方式被空格。enter…and travel…是一种方式，而inject…directly是另外一种方式，因此空格体现前后两种方式的“对立关系”，填一个负向词。 suggest表明，intensify加剧，elucidate解释，satisfy使满意，obviate使…不必要。 只有E是负向词，答案选E。
