Paragraph 1: By 1850 the United States possessed roughly 9,000 miles of railroad track; then years later it had over 30,000 miles, more than the rest of the world combined. Much of the new construction during the 1850s occurred west of the Appalachian Mountains – over 2,000 miles in the states of Ohio and Illinois alone.

1. According to paragraph 1, each of the following is true about railroad track in the United States EXCEPT:

A. In 1850 the United State had less than 10,000 miles of railroad track.

B. By the end of the 1850s, Ohio and lllinois contained more railroad track than any other state in the country.

C. Much of the railroad track built in the United States during the 1850s was located west of the Appalachian Mountain.

D. By 1860 there were more miles of railroad track in the United States than in any other country.

Paragraph 2: The effect of the new railroad lines rippled outward through the economy. Farmers along the tracks began to specialize in corps that they could market in distant locations. With their profits they purchased manufactured goods that earlier they might have made at home. Before the railroad reached Tennessee, the state produced about 25,000 bushels (or 640 tons) of wheat, which sold for less than 50 cents a bushel. Once the railroad came, farmers in the same counties grew 400,000 bushels (over 10,000 tons) and sold their crop at a dollar a bushel.

2. It can be inferred from paragraph 2 that the new railroads had which of the following effects on farm communities?

A. Most new farms were located along the tracks.

B. Farmers began to grow wheat as a commercial corp.

C. Many farmer decided to grow a wider variety of crops.

D. Demand for manufactured goods increased among farmers.

Paragraph 3: The new railroad networks shifted the direction of western trade. In 1840 most northwestern grain was shipped south down the Mississippi River to the bustling port of New Orleans. But low water made steamboat travel hazardous in summer, and ice shut down traffic in winter. Products such as lard, tallow, and cheese quickly spoiled if stored in New Orleans’ hot and humid warehouses. Increasingly, traffic from the Midwest flowed west to east, over the new rail lines. Chicago became the region’s hub, linking the farms of the upper Midwest to New York and other eastern cities by more than 2,000 miles of track in 1855. Thus while the value of goods shipped by river to New Orleans continued to increase, the South’s overall share of western trade dropped dramatically.

3. The word “bustling” in the passage is closest in meaning to

A. famous

B. important

C. growing

D. busy

4. According to paragraph 3, in what way did the new rail networks change western trade?

A. Northwestern farmers almost completely stopped shipping goods by steamboat.

B. Many western goods began to be shipped east by way of Chicago rather than south to New Orleans.

C. Chicago largely replaced New York and other eastern cities as the final market for goods for the West.

D. The value of goods shipped west soon became greater than the value of goods shipped east.

5. According to paragraph 3, what was a disadvantage of shipping goods from northwestern areas to New Orleans?

A. There was no reliable way to get goods from New Orleans to eastern cities.

B. The cost of shipping goods by river to New Orleans continued to increase.

C. Goods sipped from New Orleans’ neighboring areas had a significant competitive advantage because of their lower transportation costs.

D. the temperatures and humidity.

Paragraph 4: A sharp rise in demand for grain abroad also encouraged farmers in the Northeast and Midwest to become more commercially oriented. Wheat, which in 1845 commanded $1.08 a bushel in New York City, fetched $2.46 in 1855; in similar fashion the price of corn nearly doubled. Farmers responded by specializing in cash crops, borrowing to purchase more land, and investing in equipment to increase productivity.

6. Paragraph 4 supports the idea that the price of wheat more than doubled between 1845 and 1855 because

A. the price of corn nearly doubled during that same period

B. demand for grain increased sharply outside the United States

C. farmers in the Northeast and Midwest began to specialize in cash crops

D. many farmers had borrowed heavily to purchase land and equipment for raising wheat
