问题 At first the ______ of color pictures over a long distance seemed impossible, but, with painstaking efforts and at great expense, it became a reality.

选项 A、transaction
B、transmission
C、transformation

答案B

解析 近形近义题。四个选项拼写形式非常相似,但意义差别很大。选项[A]“交易,业务”;选项[B]“播送,传播”,一般指传播图片、信息、数据等;选项[C]“转变,变革”,一般指内在的、彻底的变革;选项[D]“转变,过渡”,一般指过渡的过程。根据题干,这里说的是长途传送图片,选项[B]符合题意,是答案。
