Choice C is the best answer because it most effectively uses data from the graph to complete the statement about the US national park with the highest number of recreation visits during a three-month period. The line graph shows the number of recreation visits to four US national parks for the months of June, July, and August 2021. According to the graph, the number of recreation visits to Yellowstone National Park in June was approximately 940,000; in July, the number of visits was approximately 1,080,000; and in August, the number of visits was approximately 920,000. In all three months, the number of visits to Yellowstone was higher than the number of visits to any other park in each month.
Choice A is incorrect. According to the graph, the number of recreation visits to Zion National Park was approximately 680,000 in June, about 580,000 in July, and about 470,000 in August, each of which is lower than the number of visits to Yellowstone in the same months. Choice B is incorrect. According to the graph, the number of recreation visits to Rocky Mountain National Park was approximately 670,000 in June, about 900,000 in July, and about 750,000 in August, each of which is lower than the number of visits to Yellowstone in the same months. Choice D is incorrect. According to the graph, the number of recreation visits to Grand Canyon National Park was approximately 540,000 in June, about 560,000 in July, and about 430,000 in August, each of which is lower than the total visits to Yellowstone in the same months.
