A.a social and commercial environment
B.high speed networking and computing
C.three rapidly evolving technologies
D.simultaneous use of voice, video, image and data请帮忙给出正确答案和分析,谢谢!

参考答案

正确答案:B
解析:由题干中的anywhere与原文定位句中location-independent相对应,可定位到原文首段末尾A location-independent user environment,which uses high speed networking and computing for multimedia communications.[精析] 逻辑推理题。题干问的是使用者可以随时随地通过网络交谈的原因。联系上下文,可知uses high speed networking and computing for multimedia communications为原因所在。B)表述与之相符,故为正确答案。[排除干扰] A)、C)和D)均在原文出现,但是联系原文可推知它们并非题干所问的直接原因,都是间接原因,不全面也不完整,故均排除。
