问题 Noise suppression in phones can play an important role in making cellphone networks more efficient, since when sounds that are________ to the meaningful signal are transmitted, precious network bandwidth is wasted.
A. unsuitable
B. detrimental
C. irrelevant
D. confined
E. limited
F. extraneous

选项

答案 C，F

解析 -方程等号：when，同义重复。
-强词和对应：当传输对于重要信号空格的声音的时候，珍贵的带宽被浪费了，强词是wasted，指向空格，根据when同义重复，空格应填入wasted的同义词。选项里有两组同义词，第一组是irrelevant与extraneous不重要的，第二组是confined与limited有限的，答案选择CF。其他选项，unsuitable不合适的，detrimental有害的。
