Answer:
1. What might be the costs of having such a large national debt?
When a country has a very large debt like the U.S., people may think that the country will not be able to pay off the debt. It's the same situation as a person who has a lot of debt, even more debt in a year than income in a year: people will believe that he or she will probably not be able to pay off the debt.
When this happens, people will invest less in the economy, the debt will become more expensive because the interest rate will be higher, and this in turn could lead Congress to enact policies such as tax hikes or debt renegotiations, which are always negative for an economy.
2. Did the promise that tax cuts would result in a growing economy that would pay for any budget shortfalls come true during the Reagan years?
Reagan's tax cuts did not lead to increases in tax revenue. On the contrary, tax revenue, as predicted by many, actually fell. This, in addition to increased military and social security spending, led to large budget deficits during the Reagan administration.
1. = A. monopoly
In regard to some city infrastructure services, it is seen as beneficial to have a single supplier. For instance, water and sewer systems tend to be operated as a single entity under city or county supervision. Cable television service, however, is an area where having business competition likely would be good for a city's residents. Licensing only one cable provider gives a monopoly to that company. It may happen, though, in small towns where the municipal government needs to attract a company to do business there.
2. = C. inelastic
As defined by <em>Investopedia, </em>demand elasticity "refers to how sensitive the demand for a good is to changes in other economic variables, such as prices and consumer income
." Demand is said to be elastic when even small changes in price will affect consumers' buying habits for that product. If the price goes down a little, shoppers will stock up at the lower price. If the price goes up a little, shoppers will hold off on buying and wait for the price to drop. This can happen with food products, where shoppers may simply change to different menu items because a particular food item's price has spiked for a time. Inelastic demand means that changes in price will have less effect on consumers' buying habits. They still need and purchase the product or service in the same amounts even if prices go up slightly. This happens with gasoline, for instance. The price at the pump may be 10 cents higher this week, but you still fill your gas tank. Or cell phone service remains a consumer commitment even though prices fluctuate.
3. = C. producers to supply more and consumers to buy less.
Think of a high price as saying to producers, "Go, go, go!" There is obvious demand for the product that has pushed the price high--so the more you can make and sell, the more you as a supplier will profit. At the same time, the high price is saying to consumers, "Whoa, whoa, whoa! Slow down!" High prices will tell consumers to hold off on purchasing something and assess whether they really need it or can afford it. Even if the product is needed, consumers may wait, in hopes that prices will come down before long, or buy less of the product than they would have if prices were lower.
Answer and Explanation:
Archaeologists and historians believed that human beings ceased to be nomads and began to settle in permanent homes after the agricultural revolution. This made human beings realize that it would be better to live in one place and plant their own food, than to hunt. This proved to be very useful for the civilization that was beginning to establish itself, however, in order to practice productive agriculture it was important to establish the division of labor, where each member of the community would be responsible for a certain function that would work in harmony with the other members.
This division of labor promoted rapid agricultural production, allowing the food produced to feed the community and be left over, promoting a surplus of food. This generated the first steps of the trade and a somewhat rudimentary economy, but very efficient to follow the human evolution over the years.
