Describe the location of the Tang and Song Dynasties relative to two oceans.

China

Explanation:

The Song dynasty (960-1279) follows the Tang (618-906) and the two together constitute what is often called "China's Golden Age." The use of paper money, the introduction of tea drinking, and the inventions of gunpowder, the compass, and printing all occur under the Song. (The fact that the dynasty spans the year 1000 may make it easier for students to locate these developments in time.)

While short-lived, the Sui Dynasty  built a strong foundation for the great achievements of the next dynasty, the Tang (tahng). The Tang Dynasty ruled for nearly 300 years (618–907). The Tang  emperor who began these achievements was Tang Taizong. His brilliant reign lasted from 626 to 649.

as university of miami psychologists debra lieberman and adam smith pointed out in a recent article in the journal current directions in psychological science, humans have social and psychological mechanisms to deter incest. with very few exceptions, marriages between brothers and sisters and between parents and their children are verboten in every human culture. the primary psychological anti-incest mechanism is the yuck response. even the idea of sex with their mom or dad, bro or sis is upsetting to most people. the psychologist jonathan haidt has found that nearly everyone is repelled by the prospect of brother-sister sex, even in hypothetical situations in which there is no chance of pregnancy).

the biological cost of incest

this raises an interesting question: just what’s so bad about incest? sure, having sex with your dad or your sister seems gross — but why? some anthropologists have argued that incest taboos are learned social conventions. this explanation, however, doesn’t make sense to me as it does not explain the widespread existence of anti-incest mechanisms in creatures ranging from cockroaches to chimpanzees. second, the incest taboo is about as close to a universal law as human moral rules get.

why should mechanisms to avoid incest be so widespread both in nature and across human societies? the answer is simple. the problem with having sex close with relatives is that there is an astonishingly high chance that your offspring will be born with a serious birth defect.
