Which of the following early North America cultures were known for building wigwams and long houses?

A. Eastern cultures
B. Great Plains Cultures
C. Western cultures
D. Northern cultures

A. Eastern cultures

The cultures known for building wigwams and longhouses in early North America were the Eastern cultures.

To determine which of the early North America cultures were known for building wigwams and longhouses, we need to look at the characteristics of each option provided:

A. Eastern cultures: This option is vague. The Eastern part of North America had numerous indigenous cultures and tribes with various architectural styles, so it is not specific enough to determine if they built wigwams and longhouses.

B. Great Plains Cultures: The Great Plains Cultures, such as the Sioux, Cheyenne, and Comanche, were known for their nomadic lifestyles and relied heavily on buffalo hunting for sustenance. They didn't typically build permanent structures like wigwams or longhouses.

C. Western cultures: Similar to the Eastern cultures, the Western part of North America had various indigenous groups, such as the Navajo and Pueblo people. Again, this option is not specific enough to determine if they built wigwams and longhouses.

D. Northern cultures: The indigenous cultures of the Northern part of North America, including the Iroquois and Algonquin people, were known for building both wigwams and longhouses. These structures provided shelter in their semi-permanent settlements.

Therefore, the correct answer is D. Northern cultures, as they were known for building wigwams and longhouses.
