By far the most important United States export product in the eighteenth and nineteenth centuries was cotton, favored by the European textile industry over flax or wool because it was easy to process and soft to tile touch. Mechanization of spinning and weaving allowed significant centralization and expansion in the textile industry during

this period, and at the same time the demand for cotton increased dramatically. American producers were able to meet this demand largely because of tile invention of the cotton gin by Eli Whitney in 1793. Cotton could be grown throughout the South, but separating the fiber – or lint – from the seed was a laborious process. Sea island cotton was relatively easy to process by hand, because its fibers were long and seeds were concentrated at the base of the flower, but it demanded a long growing season, available only along the nation's eastern seacoast. Short-staple cotton required a much shorter growing season, but the shortness of the fibers and their mixture with seeds meant that a worker could

hand-process only about one pound per day. Whitney's gin was a hand-powered machine with revolving drums and metal teeth to pull cotton fibers away from seeds. Using the gin, a worker could produce up to 50 pounds of lint a day. The later development of larger gins, powered by horses, water, or steam, multiplied productivity further.

The interaction of improved processing and high demand led to the rapid spread of the cultivation of cotton and to a surge in production. It became the main American export, dwarfing all others. In 1802, cotton composed 14 percent of total American exports by value. Cotton had a 36 percent share by 1810 and over a 50 percent share

in 1830. In 1860, 61 percent of the value of American exports was represented by cotton. In contrast, wheat and wheat flour composed only 6 percent of the value of American exports in that year. Clearly, cotton was king in the trade of the young republic. The growing market for cotton and other American agricultural products led to an unprecedented expansion of agricultural settlement, mostly in the eastern half of the United States---west of the Appalachian Mountains and east of the Mississippi River.

Which of the following can be inferred from the passage about cotton production in the United States after the introduction of Whitney's cotton gin?

A. More cotton came from sea island cotton plants than before.

B. More cotton came from short-staple cotton plants than before.

C. Most cotton produced was sold domestically.

D. Most cotton produced was exported to England.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 35 to 42.

The development of genetically modified (GM) plants and animals had led to a huge global controversy. Opponents say that GM “Frankenfoods” are a threat to our well-being, and proponents say that the risks are minimal. There is one aspect of the war over GM that is often overlooked. Anyone who wears a cotton shirt these days is using a GM crop. Cotton is the only major non-food GM crop at present, but others are coming.

GM cotton plants that are not food have not stopped the most passionate GM opponents from objecting. If GM cotton is grown in a field next to fields of non- GM cotton, they argue, then how to keep genes from being transferred from field to field. This danger, however, is not as compelling to the public as possible health hazards in food, so there is no great fury over GM cotton.

GM cotton seeds produce higher yields, and they do without the need for pesticides. Planting of GM cotton has increased fivefold since 1997; three-quarter of cotton in America, and over half in China, is now GM. Farmers like it because it increases their profits.

Other options for non-food GM include new variety of flowers with different colors or scents, tougher grasses for lawns, and plants designed to soak up pollutants from the soil. The paper industry provides another example of potential for GM to help produce better and cheaper products. Paper is made from pulp, and pulp is generally made from trees. Researchers in New Zealand and Chile have been working on insect-resistant pines, and a Japanese firm has combined carrot genes with tree genes to make them grow better in poor soil.

Another interesting case is that of tobacco. It is not food crop, but it is consumed, and GM tobacco plants with both more and less nicotine have been created. The tobacco plant, however, is an ideal target for GM, since its genetics are very well understood and it produces a lot of leaves. The value of the drugs that could be produced by GM tobacco is so high, many fanners could switch from growing tobacco for cigarettes to growing it for medicine. Since medical cost is rising, consumers would also be happy to use drugs produced in bulk by GM tobacco.

Why does the author mention a cotton shirt in the first paragraph?

A. to show that cotton is one of the most popular materials for clothing

B. to give an example of a common GM product that is not a food

C. to give an example of a controversy surrounding GM products

The Origin of Jeans

In 1853, the California gold rush was in full swing and everyday items were in short supply. Levi Srrauss, a 24-year-old German immigrant, left New York for San Francisco with a small supply of dry goods with the intention of opening a branch of his brother’s New York dry goods business. Shortly after his arrival, a prospector wanted to know what Mr. Strauss was selling. When Strauss told him he had rough canvas cloth to use for tents and wagon covers, the prospector said, “You should have brought trousers!”, because he couldn’t find a pair of trousers strong enough to last.

Levi Strauss had the canvas made into work trousers. Miners liked the trousers, but complained that the fabric was not very comfortable and tended to chafe. Levi Strauss substituted the canvas with a twilled cotton cloth from France called “serge de Nimes.” The fabric later became known as denim and the trousers were nicknamed blue jeans. Then Levi Strauss and Nevada tailor David Jacobs co-patented the process of putting small metal rivets in places such as the sides of the pockets that needed extra strength. On May 20, 1873, they received U.S. Patent No. 139.121 This date is now considered the official birthday of“blue jeans”

But why were they called blue jeans? Denim is unique in its singular connection with one color. It is made from thread that is traditionally dyed with the blue pigment obtained from indigo dye. Indigo was linked with practical fabrics and work clothing. The durability of indigo as a color and its darkness of tone made it a good choice when frequent washing was not possible.

Which best describes indigo dye?

A. A long lasting, practical color that did not show dirt.

B. A color used on all kinds of fabric to make the fabric stronger.

C. A very rare and desirable color that was difficult to create.

D. An affordable dark color that was only used by poor people.

GM cotton plants that is not food has not stopped the most passionate GM opponents from objecting. If GM cotton is grown in a field next to fields of non-GM cotton, they argue, then how to keep genes from being transferred from field to field. This danger, however, is not as compelling to the public as possible health hazards in food, so there is no great fury over GM cotton.

GM cotton seeds produce higher yields, and they do without the need for pesticides. Planting of GM cotton has increased five fold since 1997; three-quarter of cotton in America, and over half in China, is now GM. Farmers like it because it increases their profits.

Other options for non-food GM include new variety of flowers with different colors or scents, tougher grasses for lawns, and plants designed to soak up pollutants from the soil. The paper industry provides another example of potential for GM to help produce better and cheaper products. Paper is made from pulp, and pulp is generally made from trees. Researchers in New Zealand and Chile have been working on insect-resistant pines, and a Japanese firm has combined carrot genes with tree genes to make them grow better in poor soil.

Another interesting case is that of tobacco. It is not food crop, but it is consumed, and GM tobacco plants with both more and less nicotine have been created. The tobacco plant, however, is an ideal target for GM, since its genetics are very well understood and it produces a lot of leaves.
