  GOAL: ENDING CHILD LABOR

    Carefully guiding a needle that's longer than his tiny fingers, a young boy in Pakistan stitches together the leather pieces of a soccer ball. He sits crouched in the corner of a hot, airless shed for 12 hours. For his long day's work, he will earn 60 cents.

    The boy is one of more than 200 million children who work at hard, sometimes dangerous jobs all over the world. Child labor exists in two-thirds of the world's nations. From Indonesia to Guatemala, poor children as young as six are sent off to work. Often they are mistreated and punished for not working hard enough. Children mix the gunpowder for firecrackers in China and knot the threads for carpets in India, all for pennies a day. Sometimes they are sold as slaves.

    In a speech to the Child Labor Coalition when he was U.S. Secretary of Labor, Robert Reich expressed gratitude for the organization's work to end abuse of child labor, "You turned up the heat, and you got results." He also congratulated Craig Kielburger, then 13, of Canada, who traveled the world for a year fighting for kids' rights. Craig believes kids can make a difference. He offers this advice, "Write letters to companies and government officials. Put pressure on leaders to make changes and to stop the misuse of children."

    One solution to the child-labor problem in poor countries is education. "The future of these countries," Secretary Reich declared, "depends on a work force that is educated. We are prepared to help build schools."

    Education has helped to make the world a brighter place for one youth, Aghan of India. When he was nine, Aghan was kidnapped from his home and sold to a carpet maker. Aghan's boss was very cruel. "I was always crying for my mother," he recalls. Aghan's dream was to learn to write so that he could send letters to his parents. Fortunately, a group that opposes child labor rescued Aghan from the factory. He was sent to a shelter in New Delhi where he worked hard to learn to write.

A. start to Work only after age 13. 

B. start to work only after age 12. 

C. make only 60 cents an hour. 

D. may make only 60 cents a day.

  Most of the early houses built in America were suited to farm life, as it was not until cities became manufacturing centers that colonists could survive without farming as their major occupation. Among the earliest farmhouses in America were those built in Plymouth Colony. Generally they consisted of one large rectangular room on the ground floor, called a hall or great room and having a fireplace built into one of the walls, and a loft overhead. Sometimes a lean-to was attached alongside the house to store objects such as spinning wheels, firewood, barrels, and tubs. The furnishings in the great room were sparse and crudely built. Tabletops and chest boards were split or roughly sawed and often smoothed only on one side. Benches took the place of chairs, and the table usually had a trestle base so it could be dismantled when extra space was required. One or two beds and a six-board chest were located in one corner of the room. The fireplace was used for heat and light, and a bench often placed nearby for children and elders, in the area called the inglenook.

    The original houses in Plymouth Colony were erected within a tall fence for fortification. However, by 1630 Plymouth Colony had 250 inhabitants, most living outside the enclosure. By 1640, settlements had been built some distance from the original site. Villages began to emerge throughout Massachusetts and farmhouses were less crudely built. Windows brought light into homes and the furnishings and décor were more sophisticated.

    As more diversified groups of immigrants settled the country, a greater variety of farmhouses appeared, from Swedish long-style houses in the Delaware Valley to saltbox houses in Connecticut, Dutch-Flemish stone farmhouses in New York, and clapboard farmhouses in Pennsylvania. From Georgian characteristics to Greek revival elements, farmhouses of varied architectural styles and building functions populated the landscape of the new frontier.

The word “emerge” in paragraph 2 could best be replaced with

A. proceed

B. settle

C. come out

D. appear
