At major banks in big cities, you can buy foreign currencies. The prices of these currencies are determined in world markets. With dollars we can buy marks, with these marks we can buy francs, and with these francs we can buy back dollars. If, for example, the dollar-franc price is too low with respect to the other prices, there is an immediate rush to buy dollars and sell francs, not by ordinary citizens at bank windows, but by a few large currency traders in Tokyo or New York who watch prices every minute. Such a rush drives up the dollar-franc price to the no-profit-opportunity point. There are in fact
A. Profitable businesses without any risk.
B. Business deals that produce profit.
C. Business opportunities that many people search for.
D. Trading foreign currencies and stocks.

Passage 3
In economics, demand implies something slightly different from the common meaning of the term. The layman, for example, often used the term to mean the amount that is demanded of an item. Thus, if the price were to decrease and individuals wanted more of the item, it is commonly said that demand increases. To an economist, demand is a relationship between a series of prices and a series of corresponding quantities that are demanded at these prices. If one roads the previous sentences carefully, it should become apparent that them is a distinction between the quantity demanded and demand. This distinction is often a point of confusion and we all should be aware of and understand the difference between these two items. We repeat, therefore, that demand is a relationship between price and quantities demanded, and therefore suggests the effect of one (e.g., price) on the other (e.g. quantity demanded) . Therefore, knowledge of the d

Small, Imperfectly Formed
One has to look a long time for an American politician of any political stripe who has failed to laud small businesses. Still, many have little clue as to what makes such businesses succeed or fail.
Federal agencies aimed at helping small business, such as the Small Business Administration and the Minority Business Development Agency, have been around for half a century, yet persistent differences remain between the performance of businesses founded by white, male entrepreneurs and the rest. Blacks are less likely to be self-employed, for example, and when they are their businesses, on average, have lower sales and profits than do their white-or Asian-owned counterparts. If researchers could explain the causes of these differences, policy-makers could (at least in theory) supply small businesses with more useful help.
