问题 Rarely______a technological development______an impact on many aspects of social, economic, and cultural development as greatly as the growth of electronics.

选项 A、has...had
B、had...had
C、has...has
D、have...had

答案A

解析此句是说很少有一项科技的发展能够像电子技术的发展那样，对我们的社会、经济、文化等诸多方面产生如此重要的影响。根据句意可判断，此句的时态应为现在完成时，句子的基本结构为：主语+have／has+动词的过去分词。主语a technological development为单数形式，否定副词rarely置于句首时，句子应部分倒装，即将助动词has提前，因此A项正确。
