In the course of history, human inventions have dramatically increased the average amount of energy available for use per person. Primitive people in cold regions burned wood and animal dung to heat their caves, cook food, and drive off animals by fire. The first step toward the developing of more efficient fuels was taken when people discovered that they could use vegetable oils and animal fats in lieu of gathered or cut wood. Charcoal gave off a more intensive heat than wood and was more easily obtainable than organic fats. The Greeks first began to use coal for metal smelting in the 4^th century, but it did not come into extensive use until the Industrial Revolution.

In the 1700s, at the beginning of the Industrial Revolution, most energy used in the United States and other nations undergoing industrialization was obtained from perpetual and renewable sources, such as wood, water streams, domesticated animal labor, and wind. These were predominantly locally available supplies. By mid-1800s, 91 percent of all commercial energy consumed in the United States and European countries was obtained from wood. However, at the beginning of the 20^th century, coal became a major energy source and replaced wood in industrializing countries. Although in most regions and climate zones wood was more readily accessible than coal, the latter represents a more concentrated source of energy. In 1910, natural gas and oil firmly replaced coal as the main source of fuel because they are lighter and, therefore, cheaper to transport. They burned more cleanly than coal and polluted less. Unlike coal, oil could be refined to manufacture liquid fuels for vehicles, a very important consideration in the early 1900s, when the automobile arrived on the scene.

By 1984, nonrenewable fossil fuels, such as oil, coal, and natural gas, provided over 82 percent of the commercial and industrial energy used in the world. Small amounts of energy were derived from nuclear fission, and the remaining 16 percent came from burning direct perpetual and renewable fuels, such as biomass. Between 1700 and 1986, a large number of countries shifted from the use of energy from local sources to a centralized generation of hydropower and solar energy converted to electricity. The energy derived from nonrenewable fossil fuels has been increasingly produced in one location and transported to another, as is the case with most automobile fuels. In countries with private, rather than public transportation, the age of nonrenewable fuels has created a dependency on a finite resource that will have to be replaced

According to the passage, what was the greatest advantage of oil as fuel?

A. It was a concentrated source of energy

B. It was lighter and cheaper than coal

C. It replaced wood and coal and reduced pollution

D. It could be converted to automobile fuel

Read the following passage and mark the letter on your answer sheet to indicate the correct answer

Before photography was invented in 1839, painted portraits, and engravings based on them, were one of the few ways to record likenesses. From the Colonial era through the 1820s, portraiture was the most widely practiced genre of American art, and it continued to be a significant form through the 19th century. The demand for likenesses was incessant, and portraiture was often the primary source of income for artists. Artists frequently made portraits of famous people to attract interest and potential patrons. For example, in 1834 Chester Harding painted frontiersman Davy Crockett, then a member of the U.S. House of Representatives, for display in his Boston gallery.

A consistent belief through most of the 18th and 19th centuries was that character could be read from a person's face, or the bumps on his or her head, or from facial expressions, and that portraits should convey these indicators of character. These theories of physiognomy and phrenology have since been debunked, but they were important considerations in depicting the nation's leaders, since such portraits were often made for posterity. Most people had only one portrait painted in their lifetime, if at all, so artists were selected with great care, and expectations were high.

Before the 1840s, American portraiture was influenced primarily by English techniques, poses, compositions and gestures, and many artists received at least part of their training in England. Even canvas sizes followed the British example. Portraits made on commission were priced according to canvas size and the materials and labor involved.

In the late 19th century as European portraitists began traveling to the United States to acquire commissions from the growing upper class, American artists increasingly felt they needed to train abroad in order to succeed at home. Paris continued to be the main lure. as painters such as Eakins, Whistler, Beaux and Sargent went to study there. Some of America's best-known portraitists, in fact, became expatriates.
