单选题 The new technological revolution in American newspapers has brought increased issue volume , a wider range of publications and an expansion of newspaper jobs.

A、 manipulation
B、 reproduction
C、 circulation
D、 penetration

【正确答案】 C

【答案解析】[解析] 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”。此三项均不合题意。
