Study the map of railroads and cattle trails in America’s West. How did the direction of railroads differ from those of the cattle trails, and to what can this difference be attributed? 

a. Cattle trails ran east-west, and most railroads followed their routes because the railroads needed to bypass major towns.

b. Cattle trails ran north-south, and most railroads followed their routes to bring much-needed supplies to America’s expanding southwest.

c. Cattle trails ran north-south, but most railroads ran east-west to enable people and supplies to move quickly across the plains and mountains.

d. Cattle trails ran north-south, but most railroads ran east-west because this is how the major rivers in America’s West flowed.
