To answer these questions, we can analyze the provided options and eliminate incorrect choices until we find the correct answer.

Question 1: What natural resource attracted other nations to trade with West and Central Africa beginning around AD 750?

To determine the correct answer, let's evaluate each option:

A. Copper: Copper is not a primary natural resource that attracted other nations to trade with West and Central Africa during that time period.

B. Silver: Silver is also not a primary natural resource associated with West and Central Africa's trade attraction.

C. Gold: Gold is the correct answer. West and Central Africa had significant gold mines, such as the famous empire of Ghana, that attracted trade and wealth from other nations during that time period.

D. Salt: While salt was also an important commodity traded throughout the region, it was not the main resource that attracted other nations.

Therefore, the answer is C. gold.

Question 2: Which of the following is an example of how people have adapted to the environment of West and Central Africa?

A. They do not cut down trees to make more arable land: This option demonstrates adaptation by preserving trees and not deforesting the land, which helps maintain the balance of the ecosystem.

B. They leave mineral deposits alone: This option does not demonstrate adaptation to the environment of West and Central Africa, as it does not specify any actions related to adaptation.

C. They use what arable land there is for farming: While using available arable land for farming is a practical approach, it does not specifically address adaptation to the environment.

D. They do not live near water: This option does not demonstrate adaptation, as water is a crucial resource for human settlement and development.

Therefore, the answer is A. They do not cut down trees to make more arable land.

Question 3: In Algeria, a stable government has been difficult to maintain due to?

A. Ban of fair elections: This option suggests restrictions on fair elections, which could contribute to political instability.

B. Violent Islamic extremists: This option is correct. Extremist groups, such as Islamic fundamentalists, have been a significant cause of instability and conflict in Algeria.

C. A lack of secularism in the government: While a lack of secularism can sometimes lead to political tensions, it is not the main reason for the difficulty in maintaining a stable government in Algeria.

D. Poor economic performance: While poor economic performance can contribute to political instability, it is not the main reason stated in the question.

Therefore, the answer is B. Violent Islamic extremists.
