All,
I've sent you this clipping from the USA Daily on newspaper circulation to make a point. We have been feeling pressure from above to increase circulation. But this year's numbers are up two percent compared to last year's! That is magnificent when you consider that firstly, our population base here in the Kelbyville area has actually shrunk by four percent in the last year; and secondly, almost none of the major newspapers in the nation are doing as well as we are. So I want to say congratulations to everybody. You are doing terrific, terrific work and I am well aware of it.
Keep it up.
What does the table show？

A. The percent change in circulation from a year earlier.
B. The percentage of market share each newspaper controls.
C. The annual revenue generated by weekday newspaper sales.
D. The total number of newspapers sold over the past 6 months.
