I think you need to look again at #21.

I agree with #22

Would #21 be D?

-MC

I would go with A.... people learn to adapt to new environments. They learn how to change their habits and in addition, the find ways to make the new environment more habitable. Think about the researchers at Antarctic

Alright, thank you

To check if your answers are correct:

21. How do people survive living in harsh environments such as the desert?
To determine if your answer is correct, let's examine the choices provided:
a. by adapting and making changes to their environment
b. by moving to more hospitable areas
c. by not altering the natural landscape of their environments
d. none of the above

To find the correct answer, we can eliminate the options that are obviously incorrect. Option b could be a temporary solution, but it doesn't address long-term survival in the desert. Option c also seems unlikely as people often need to make alterations to adapt to extreme conditions.

Therefore, the most logical answer based on the provided choices is a. by adapting and making changes to their environment. This option aligns with the idea that people need to adjust their way of living, use innovative techniques, and make modifications to thrive in harsh environments like the desert.

So, your answer of C is incorrect. The correct answer is a. by adapting and making changes to their environment.

23. By which of the following are modern economic systems distinguished from one another?
To verify if your answer is correct, let's analyze the options:
a. means of production
b. kinds of goods and services produced
c. amount of investment capital
d. degree of government involvement

To find the correct answer, we need to consider how economic systems differ from one another. Options a, b, and c are relevant factors but not sufficient to distinguish one economic system from another.

The most compelling option is d. degree of government involvement. Different economic systems can have varying levels of government intervention, such as planned economies with high government control (e.g., socialism or communism) versus market economies with limited government interference (e.g., capitalism).

Therefore, your answer of D is indeed correct. Modern economic systems are distinguished from one another by the degree of government involvement.

In summary:
21. The correct answer is a. by adapting and making changes to their environment.
23. Your answer of D is correct. Modern economic systems are distinguished from one another by the degree of government involvement.
