Rounded to the nearest hundred-thousand, the population of Capital City is 7,300,000 and the population of Spring City is 3,900,000. 
To estimate how much larger Capital City is than Spring City, we subtract the rounded population of Spring City from the rounded population of Capital City: 
7,300,000 - 3,900,000 = 3,400,000. 
Therefore, the best choice is B.
