Answer:
The answer is the aging process.
Explanation:
Most people reflect the same cognitive changes as they age. A normal aging process involves a slight decrese in memory and though processing at around age sixty. However, most changes do <u>not</u> impede the person from functioning in society. Moreover, some abilities such as language use are likely to improve.
Qin: strict ruler, legalist government, and the great wall of china.
Han: nicer ruler, silk road, Confucianism was main form of government.<span />
The answer could be either A. or C. I'm leaning more into C. because scarcity means having short supply of something, and having not enough resources doesn't satisfy all of ones needs.
Hope this helps!
