4. using the same amount of resources, aanand can either build 6 models or prepare 4 experiments, and pam can
either build 9 models or prepare 6 experiments. who has the comparative advantage in building models and
who has the comparative advantage of preparing experiments?
a. pam has a comparative advantage in building models; both people have a comparative advantage in
preparing experiments
b. neither has a comparative advantage in producing either good
c. aanand has a comparative advantage in building models and pam has a comparative advantage in
preparing experiments
d. both have a comparative advantage in producing both goods.

All answers are incorrect.

Explanation:

Comparative advantage is "the ability of an individual or group to carry out a particular economic activity (such as making a specific product) more efficiently than another activity.” Because both Pam and Aanand build models more efficiently than they prepare experiments, they both have a comparative advantage in building models. Your textbook sucks because none of the available answers reflect this. Even if the textbook were incorrectly comparing worker efficiency instead of overall product production efficiency, none of the answers reflect the fact that Pam has comparative advantage in producing both models and experiments.

since most of current immigration into the u.s., both legal and illegal, is coming from latin america. it would be very difficult to imagine or rationalize a country my fellow citizens are trying desperately to flee into, would pose a threat to my prosperity or freedom. since the u.s. has a long history of intervention, but no record of permanent occupation, i would not feel oppression is the main objective.  

the largest free trade nation, along with the largest gdp in the world wanting to expand it's economic policy on us, and including us, could only be positive. the u.s. government has no interest in, or way of simply forcing american culture on us. and has no track record of it. other nations that adopted american social culture, or "americanization" did so voluntarily, mainly through the choice of allowing american businesses and u.s. citizens to come into their nations, as free operatives.

`stare decisis is a legal doctrine that obligates courts to follow historical cases when making a ruling on a similar current or future case. stare decisis ensures that cases with identical facts be approached in the same way, unless overruled by the same court or a higher court such as the us supreme court. simply put, it binds courts to follow legal precedents set by previous decisions.

stare decisis is a latin term meaning "to stand by that which is decided".
