问题 Digital technologies really began to take form when ______.
The example of photography is used to show ______.
选项 A、how digital technology has replaced traditional film
B、the enormous storage advantages of digital technology
C、how digital technology has improved the quality of production
D、how economical it is to use digital technology since it stores so much
答案B
解析 事实细节题。The example of photography出现在第二段第一句。从题干中is used to show可以判断此题考查的是，文章举摄影为例的目的是什么。从第二段第二句中的collect vast amounts of data和第三句中的store 300 times more information than a decade ago可以看出，作者要通过这个例子说明数字技术有“信息存储量大”的优势。这正是选项B的内容。
