问题 Clearly refuting skeptics, researchers have (i)____ not only that gravitational radiation exists but that it also does exactly what theory (ii)____ it should do.

选项 A、doubted…warranted
B、estimated…accepted
C、demonstrated…predicted
D、assumed…deduced
E、supposed…asserted

答案 C

解析 空格(i):
- 方程等号:逗号,同义重复。
- 强词和对应:refuting skeptics指向空格(i),根据逗号取同,体现研究者“驳斥了怀疑者”,空格填入一个正向词。doubt怀疑,estimate估计,demonstrate证实,assume假设,suppose假定。选项C合适,体现研究者通过“证实”自己的观点来反驳。
空格(ii):
- 方程等号:not only…but also…平行结构,同义重复。
- 强词和对应:it指代gravitational radiation,exists和does…it should do根据not only…but also…取同,空格(ii)不改变逻辑方向,填入一个正向词。warrant保证(对),accept接受(对),predict预测(对),deduce推断(对),assert断言(对)。综合空格(i),答案选C。
