Pаssаge 2: On the empty highwаys оf Nоrth Kоrea, a driver can park a car in the fast lane and then walk across the bumpy asphalt to get directions from someone on the other side of the road. In South Korea, such behavior on the busy highways would guarantee a quick trip to the mortuary. Even walking on Seoul's sidewalks can be a challenge because of the masses of pedestrians and vendors who steer their pushcarts like battering rams. There are comparatively few people on Pyongyang's sidewalks, practically no vendors and little of the energy evident in the South. These contrasting street scenes illustrate the sharply different systems in the two Koreas: the North's sedate and sullen dynastic communism and personality cults; the South's confusing and hectic capitalism and budding democracy. There is prosperity in South Korea, where the annual per capita income is about $4,000, which many Western and South Korean experts believe is four times higher than in secretive North Korea. Life is sometimes a colorful blur in the South; people change addresses and phone numbers frequently and drive with abandon. In the North, the pattern is like a musty still life; most people seem to stay put in drab buildings, and only a small elite have phones or cars. Yet commonalities exist under the obvious and broad differences between these countries, bitter enemies since the 1950-53 Korean War. Despite the war and four decades of isolation -- during which the divided Koreans have been unable to visit, write or call each other -- the people living on both sides of the Demilitarized Zone display remarkably similar attitudes, social values and aspirations. Family life is one example. In the North, as in the South, women control family finances, with husbands handing over their salaries to their wives. In North and South, women marry near age 23, men at about 27. A foreigner not married by what both North and South Koreans view as the proper age receives the same interrogation in Pyongyang and Seoul: "Why are you not married? When will you get married? You must get married." Even their radically opposite political cultures seem to stem from shared traits of authoritarianism, although there are great differences in the political systems of the two countries. After decades of military rule, South Korea is now moving slowly toward democracy. In North Korea, with only half as many people as the South, President Kim Il Sung was in power for 41 years, is still worshiped as a virtual deity as is his son, who appears to be in no danger of losing his grip on the country. The South Koreans are horrified at Kim's personality cult and at what they believe is an atmosphere of terror that prevents people from criticizing him. But, while none of the South's leaders ever maintained a cult like Kim's or his alleged terror, many South Koreans lived in real fear of past military rulers, particularly ex-president Chun Doo Hwan, who was in power from 1979 to 1988.

Passage 1: The size of the Earth -- about 12,750 kilometers (km) in diameter-was known by the ancient Greeks, but it was not until the turn of the 20th century that scientists determined that our planet is made up of three main layers: crust, mantle, and core. This layered structure can be compared to that of a boiled egg. The crust, the outermost layer, is rigid and very thin compared with the other two. Beneath the oceans, the crust varies little in thickness, generally extending only to about 5 km. The thickness of the crust beneath continents is much more variable but averages about 30 km; under large mountain ranges, such as the Alps or the Sierra Nevada, however, the base of the crust can be as deep as 100 km. Like the shell of an egg, the Earth's crust is brittle and can break. Below the crust is the mantle, a dense, hot layer of semi-solid rock approximately 2,900 km thick. The mantle, which contains more iron, magnesium, and calcium than the crust, is hotter and denser because temperature and pressure inside the Earth increase with depth. As a comparison, the mantle might be thought of as the white of a boiled egg. At the center of the Earth lies the core, which is nearly twice as dense as the mantle because its composition is metallic (iron-nickel alloy) rather than stony. Unlike the yolk of an egg, however, the Earth's core is actually made up of two distinct parts: a 2,200 km-thick liquid outer core and a 1,250 km-thick solid inner core. As the Earth rotates, the liquid outer core spins, creating the Earth's magnetic field. Cutaway views showing the internal structure of the Earth are below: this view drawn to scale demonstrates that the Earth's crust literally is only skin deep.
