问题 Digital technologies really began to take form when ______.
The author implies that excitement over the digital revolution may be hindered by ______.
选项 A、ignorance of the technology
B、robust economic growth
C、the economic realities of its practicality
D、economic problems of hi-tech companies
答案D
解析 关键词digital revolution出现在第三段第一句。前半句总结上文，说明了数字技术革命好的一面；后半句用although引导，则是其不好的一面。该句中的over-shadowed与题干中的hindered意思相近，也就是说，是the struggles of high-tech industries对数字技术革命造成了负面影响。而the struggles的目的足 recover from the go-go years of the 1990s，也就是下句中的a return to robust economic growth。归根结底就是，这些高科技企业的经济问题对数字革命的成就产生了负面影响，因此选项D符合题意。
