The last one is the correct choice
The correct answer is A.
It gave settlers a quicker way to move west.
Explanation:
The Cumberland Road or National Road was a road built by the government of the U.S. between 1811 and 1837 that covered around 1000 kilometers from Maryland to Illinois. This road was relevant because although by then there were other roads this was the first major highway and also this implied settlers could go to the West of the territory in an easier and quicker way. Indeed for many years, this was the road taken by those that wanted to travel to the West and the North West. Therefore, the Cumberland Road was significant mainly because it gave settlers a quicker way to move west.
On the morning of September 11, 2001, four airliners were hijacked by members of al-Qaeda who aimed to carry out suicide attacks against important targets in the United States. Of the four planes, one struck the Pentagon, one crashed in a field in Pennsylvania, and the two remaining planes were flown into the Twin Towers in New York City. Claiming almost three thousand lives, this event gave birth to a war and brought about everyday sociological changes for Americans.
