The new technological revolution in American newspapers has brought increased______, a wider range of publications and an expansion of newspaper jobs.
【正确答案】
C
【答案解析】四项选择都是以一tion结尾的名词，但意思完全不同。circulation可表示书报的发行量，如：a newspaper with a daily circulation of 500，000(日发行量为50万份的报纸)。可用于本题。manipulation“操作”，reproduction“再生产”，penetration“穿透”均不合题意。
