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.
According to anthropologists, people in preindustrial societies spent 3 to 4 hours per day or about 20 hours per week doing the work necessary for life. Modern comparisons of the amount of work performed per week, however, begin with the Industrial Revolution (1760-1840) when 10- to 12-hour workdays with six workdays per week were the norm. Even with extensive time devoted to work, however, both incomes and standards of living were low. As incomes rose near the end of the Industrial Revolution, it became increasingly common to treat Saturday afternoons as a half-day holiday. The half holiday had become standard practice in Britain by the 1870's, but did not become common in the United States until the 1920's.
In the United States, the first third of the twentieth century saw the workweek move from 60 hours per week to just under 50 hours by the start of the 1930' s. In 1914, Henry Ford reduced daily work hours at his automobile plants from 9 to 8. In 1926 he announced that henceforth his factories would close for the entire day on Saturday. At the time, Ford received criticism from other firms such as United States Steel and Westinghouse, but the idea was popular with workers.
The Depression years of the 1930's brought with them the notion of job sharing to spread available work around; the workweek dropped to a modem low for the United States of 35 hours. In 1938 the Fair Labor Standards Act mandated a weekly maximum of 40 hours to begin in 1940, and since that time the 8-hour day, 5-day workweek has been the standard in the United States. Adjustments in various places, however, show that this standard is not immutable. In 1987, for example, German metalworkers struck for and received a 37.5-hour workweek; and in 1990 many workers in Britain won a 37-hour week. Since 1989, the Japanese government has moved from a 6- to a 5-day workweek and has set a national target of 1,800 work hours per year for the average worker. The average amount of work per year in Japan in 1989 was 2,088 hours per worker, compared to 1,957 for the United States and 1,646 for France.
What is one reason for the change in the length of the workweek for the average worker in the United States during the 1930's?
A.Several people sometimes shared a single job.
B.Labor strikes in several countries influenced labor policy in the United States.
C.Several corporations increased the length of the workweek.
D.The United States government instituted a 35-hour workweek.

Read the following passage, and mark the letter (A, B, C or D) on your answer sheet to indicate the correct answer to each question  
 Mesa Verde is the center of prehistoric Anasazi culture. It is located in the high plateus lands near Four Corners, whereColorado, Utal,New Mexico, andArizonacome together. This high ground majestic but not forbidding. The climate is dry but tiny streams trickle at the bottom of deeply cut canyons, where seeps and springs provided water for the Anasazi to irrigate their crops. Rich red soil provided fertile ground for their crops of corn, beans, squash, tobacco, and cotton. The Anasazi domestated the wild turkey and hunted deer, rabbits, and mountain sheep.
For a thousand years the Anasazi lived around Mesa Verde. Although the Anasazi are not related to the Navajos, no one knows what these Indians called themselves, and so they are commonly referred to by their Navajo name, Anasazi, which means “ancient ones” in the Navajo language.
 From 550 A.D., early Anasazi – then a nomadic people archaeologists call the Basketmakers- began constructing permanent homes on mesa tops. In the next 300 years , the Anasazi made rapid technological advancements, including the refinement of not only basket-making but also pottery-making and weaving. This phase of development is referred to as the Early Pueblo Culture.
By the Great Pueblo Period (1100- 1300 A.D.), the Anasazi population swelled to more than 5,000 and the architecturally ambitious cliff dwellings came into being. The Anasazi moved from the mesa tops onto ledges on the steep canyon walls, creating two- and three- story dwellings. They used sandstone blocks and mud mortar. There were no doors on the first floor and people used ladders to reach the first floor. All the villages had underground chambers called kivas. Men held tribal councils there and also used them for secret religious ceremonies and clan meetings. Wilding paths, ladders and steps cut into the stone led from the valleys below to the ledges on which the village stood. The largest settlement contained 217 rooms. One might surmise that these dwellings were built for protection, but the Anasazi had no known enemies and there is no sign of conflict.
But a bigger mystery is why the Anasazi occupied these structures such a short time. By 1300, mesa Verde was deserted. It is conjectured that the Anaszi abandoned their settlements because of drought, overpopulation, crop failure, or some combination of these. They probably moved sourthward and were incorporated into the pueblo villages that the Spanish explorers encountered 200 years later. Their descendants still live in the Southwest.
How long did the Early Puebbo Culture last?
A.1,000 years
B.550 years
C.200 years
D.300 years
