Final answer:
Option a) revenue from gaming facilities has steadily risen every year since 1999 best summarizes the chart information, reflecting the broader trend of increasing government revenues from various sources, including gaming, since World War II.
Step-by-step explanation:
The best summary for the information in the chart is option a) Revenue from gaming facilities has steadily risen every year since 1999. This is supported by data showing that gambling revenues have increased substantially over several years, despite temporary declines during economic downturns such as the dot-com crash 9/11, and later the Crash of 2008. Revenues for the federal, state, and local governments have shown a steady increase since the end of World War II.
Moreover, sources of revenue for local and state governments include a significant portion of taxes, with sales tax and individual income taxes composing large parts of state government revenue. Although the gaming industry generates considerable revenue, it is important to note the pattern of fluctuations due to external economic factors.
