What is the most likely reason why grid villages are the most common type of settlement found in the western us?
a.
towns in the western us are typically older than those in the east.
b.
the government distributed and sold land in square parcels.
c.
towns in the west were planned carefully prior to settlement.
d.
people centered their towns around a central city hall or church.

The answer is B. The government distributed and sold land in square parcels.

This pattern evolved in the Midwest and is usually based on the grid plan. The government sold the land by square foot hence why it is in a grid pattern. The characteristic villages of Hispanic-American districts and the Mormon, for example, followed the imposed grid plan composed of square blocks with straight streets. Each square block contained very large house lots.
