The passages are about 700 words in length. This is tho long format for tho Reading section. On the long format, you will respond to fIVe passages. After each passage, you will answer I 2- 14 questions about it. Only three passages wi ll be graded. The other passages are part of an exerimental section for fu ture tests. Because you will not know wh i ch passages will be graded, you must try to do your best on all of them.

Using a layered model 01 stratification, most sociolo- gists describe the class system In the United States as divided i nto several classes: upper, upper middle, middle, lower middle, and lower class. Each class is delined by characteristics such as income, occupational prestige, and educa- tional attainment. The different groups are arrayed along a continuum with l!2H with the most money, education, and prestige at the top and those wi th the least at the bottom. In the United States, the upper class owns the mater share 01 corporate and personal wealth; it includes Ihose who have held wealth lor generations as well as those who have recenlly become rich. Only a very small proportion of pe0- ple actually constitute the upper class, but they control vast amounts 01 wealth and power in the United States. They exercise MMWUUII: control throughout SOCiety . Most 01 their wealth Is Inherited. ~~ - II!i Each year, the business magazine Forbes publishes a list of the "Forbes 400" -the four hundred wealthiest fami ~es and individuals in the country. 01 all the wealth represented on the Forbes 400 list, more than hall is inherited. Those on the list whO could be called "sell-made" were not typically of modest origins; mosl In hemed significant assets (Forbes, 199 7; Sklar and Collins,1997). Those In the upper class with newly acquired weallh are known as the nouveau riche. Although they may have vast amounts of money, they are often not accepted into "old rich" circles. ~ The upper middle class includes those with high Incomes and high SOCial prestige. They tend to be well-educated professionals or business executives. Their earnings can be quite high indeed - successful business executives can earn millions of dollars a year. Ills difficult to estimate exactly how many people fall into th is group because of the difficulty 01 drawi ng lines between the upper, upper midd l e, and middle class. Indeed, the upper middle class is often thought of as "middle class" because the ir lifesty le sets the standard to which many aspire. but this lifestyle Is si mply beyond the means 01 a maJority 01 people In the United States. ~ The middle dass is hard to define; In part, being "middle class' is more than just economic position. By lar the majority 01 Americans Identify themselves as middle class even though they vary widely in lifestyle and In resources at their disposal. But the Idea that the United States Is an open-class system leads Malc'ltll chrancnv a' ~rTl prav~ MOOEL TEST READI NG SECTION 3 18 many to think that the majority have a middle-class lifestyle because, in general, people tend not to want to recognize class distinctions in the United States. Thu s, the middle class becomes the ubiquitous norm even though many who call themselves middle class have a tenuous hold on this class position. In the hierarchy 01 social class, the lOwer middle Cl8ss includes workers in the skilled trades and low-Income bureaucratic workers, many of whom may actualty define themselves as middle class. Examples are blue-collar workers (those in skilled trades who do manual labor) and many service workers, such as secretaries, hairdressers, waitresses, police, and firefighters. Medium to low income, education, and occupational prestige del ine the lower middle class rel- ative to the class groups above it. The term "lOwer" in this class deSignation refers to the relative position 01 the group in the stra tif ication system, but it has a pejorative sound to m any people, especially to people who are members 01 this class. -+ The lOwer class is composed P£kIi.iitiol the displaced and poor. People in this class have little formal education and are often unemployed or working In minimum-wage jobs. (!J Forty percent of the poor work; 10 percent work year- round and lull lime - a proportion thai has generally incr eased ove r time.

Scientists today have a very good understanding of the physical laws and mathematical equatJoos that govern the behavior and motion 01 atoms in the air, oceans, and land. Why, then, do we have so much trouble predicting the weather? For a long time, mos t scientists liS@r!i8d. thatthedifficultyofweather prediction would go away once we had enough weather stations to collect data from around the world aoo sufficiently powerfut computers to deal with all the data. However, we now know that weather is ru==ncIiiiiiiiiIiI!V , unpredictable on lime scales longer than a few weeks. To understand why, we must look at the nature of scientific prediction. Milt rial chrancny il ' sk~ml pravv MODEL TEST 4IAEADlNG SEC T ION 323 ~ SUppose you want to predict the looation 01 a car on a road 1 minute Ir om now. You need two basic pieces 01 Information: where the car is now, and how fast it is moving. II the car is now passing Smi th Road and heading north at 1 mile per minute, It will be 1 mile north of Smith Road in 1 minute. Now, suppose you want to predict th e weathe r. Again, you need two basic types of information: (1) the current weather and (2) how weather changes Irom one moment to the next. You oould attempt to predict the weather by creatill9 a -model world," For example, you oould overlay a globe 01 the Earth with graph paper and then specify the current temperature. pressure, cloud cover. and wind within each square. These are your starting points, or initial conditions. Next, you oo uld input all the initial co nditions into a oo mputer, along with a set of equations (physical laws) that describe the processes that can chanOA weather from one moment to the next. -+ Suppose t he initial conditions represent the weather around the Earth at this very moment and you run your computer model to predict the weather lor the next month In New York City. The model might tell you th at tomorrow will be warm and sunny, with cooling during the next week and a major sto rm passing through a month from now. Now supposo you rvn tho modol again but mako one minor change In the Inilial conditions-say, a small change In the wind speed somewhere over Brazil. ~ For tomorrow's wea th er, this slightly d ill erent initial conditiorl will not change the weather prediction lor New York City. [SI But for next month's weather, the two predictions may not agree at alll lCl The disagreement between the two predictions arises because the laws governing weather can cause very tiny changes in Initial co nditions to be greally magnified over time. IDI This extreme sensitivity to Initial conditions is sometimes called the bufterlly effect: If initial conditions change by as much as t he flap 01 a butterfly's wings, the resulting prediction may be very different. -+ The butterfly effect Is a chaotic systems. Simple systems are described by li near equations wbichJ for example, increasing a cause pro- duces a proportional increase in an In contrast, chaot iC systems are described by nonlinear equations, whk;h allow for subtler and more intrica te interactions. For example, the economy is nonlinear because a rise in Interest rates does not automatically produce a corresponding change in consumer spending. Weather Is nonlinear because a change in th e willd speed in one location does not automatically produce a correspolldlng change in another location. Many (but not all) nonlinear systems exhibit chaotic behavior. -+ Despite their name, chaotic systems are not completely random. In facl, many chaotic systems have a kind 01 underlying order that explains the general liItiiiiiIlol their behavior even wh ile details at any pa rtJc ular moment remain unpredictable. In a sense , m any chaotic systems are ·predictably unpre- dictable." Our understalldi ng of chaotic systems is increasing at a tremendous rate, bul much remains to be learned about them.
