Answer:
C. Railroad mileage increased faster than canal mileage
Explanation:
Using the graph, you can see it shows the number of miles of canals and railroads in New York.
So, try to look at the graph and compare the railroads and canals. What do you see?
You should notice that suddenly, in 1840, the railroads came out of nowhere and jumped from 0 miles to 450. Then, in 1850, they jumped from 450 to 1400, more than triple the miles.
The canals however, only slowly rised from 50-150 miles each year.
Using this information, you can say that option C, "Railroad mileage increased faster than canal mileage" is the best answer choice.
