b) the united states has an absolute advantage in sugarcane and crude oil.
c) brazil has an absolute advantage in crude oil and the united states has an absolute advantage in sugarcane.
d) brazil has an absolute advantage in sugarcane and the united states has an absolute advantage in crude oil.

D) Brazil has an absolute advantage in sugarcane and the United States has an absolute advantage in crude oil.

Explanation:

According to international trade theory, countries must specialize in the production of goods in which they have a comparative advantage over other countries. For example, if Brazil has an absolute advantage over the US in sugarcane production, it means that the country has greater sugarcane production efficiency. In turn, if the US has an absolute advantage over Brazil in oil production, it also means that the US has greater oil production efficiency. Thus, each of the countries must produce the good in which they have the absolute advantage to export it, and must import the other type of good. In this case, the US would be better off exporting oil and importing sugarcane from Brazil, and vice versa.

answer; the correct answer is (d) binge eating followed by compensatory behavior;

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.
