Of all these experts,none excelled the Pomo -a group who lived on or near the coast during the 1800"s,and whose descendants continue to live in parts of the same region to the same region to this day.They made baskets three feet in diameter and others no bigger than a thimble.The Pomo people were masters of decoration.Some of their baskets were completely covered with shell pendants;others with feathers that made the baskets"surfaces as soft as the breasts of birds.Moreover,the Pomo people made use of more weaving techniques than did their neighbors.Most groups made all their basketwork by twining -the twisting of a flexible horizontal material,called a weft,around stiffer vertical strands of material,the warp.Others depended primarily on coiling -a process in which a continuous coil of stiff material is held in the desired shape with tight wrapping of flexible strands.Only the Pomo people used both processes with equal case and frequency.In addition,they made use of four distinct variations on the basic twining process,often employing more than one of them in a single article. Although a wide variety of materials was available,the Pomo people used only a few.The warp was always made of willow,and the most commonly used welt was sedge root,a woody fiber that could easily be separated into strands no thicker than a thread.For color,the Pomo people used the bark of redbud for their twined work and dyed bullrush root for black in coiled work.Though other mater ials were sometimes used,these four were the staples in their finest basketry. If the basketry materials used by the Pomo people were limited,the designs were amazingly varied.Every Pomo basketmaker knew how to produce from fifteen to twenty distict patterns that could be combined in a number of different ways. 1.What best distinguished Pomo baskets from baskets of other groups?

Questions 13-20 Any rock that has cooled and solidified from a molten state is an igneous rock.Therefore,if the Earth began as a superheated sphere in space,all the rocks making up its crust may well have been igneous and thus the ancestors of all other rocks.Even today,approximately 95percent of the entire crust is igneous.Periodically,molten material wells out of the Earth"s interior to invade the surface layers or to flow onto the surface itself.This material cools into a wide variety of igneous rocks.In the molten state,it is called magma as it pushes into the crust and lava when it runs out onto the surface. All magma consists basically of a variety of silicate minerals (high in silicon-oxygen compounds),but the chemical composition of any given flow may differ radically from that of any other.The resulting igneous rocks will reflect these differences.Igneous rocks also vary in texture as well as chemistry.Granite,for instance,is a coarse-grained igneous rock whose individual mineral crystals have formed to a size easily seen by the naked eye.A slow rate of cooling has allowed the crystals to reach this size.Normally,slow cooling occurs when the crust is invaded by magma that remains buried well below the surface.Granite may be found on the surface of the contemporary landscape,but from its coarse texture we know that it must have formed through slow cooling at a great depth and later been laid bare by erosion.Igneous rocks with this coarse-grained texture that formed at depth are called plutonic. On the other hand,if the same magma flows onto the surface and is quickly cooled by the atmosphere,the resulting rock will be fine-grained and appear quite different from granite,although the chemical composition will be identical.This kind of rock is called rhyolite.The most finely grained igneous rock is volcanic glass or obsidian,which has no crystals.Some researchers believe this is because of rapid cooling;others believe it is because of a lack of water vapor and other gases in the lava.The black obsidian cliffs of Yellowstone National Park are the result of a lava flow of basalt running head on into a glacier.Some of the glacier melted on contact,but suddenly there also appeared a huge black mass of glassy stone. 13.In the first paragraph,the author mentions that (A)the Earth began as a molten mass (B)a thin layer of magma flows beneath the Earth"s crust (C)the minerals found in igneous rock are very common (D)igneous rock is continually being formed 14.The word "invade"in line 5is closest in meaning to (A)move into (B)neutralize (C)cover (D)deposit 15.The word "contemporary"in line 17is closest in meaning to (A)vast (B)natural (C)existing (D)uneven 16.The word "it"in line 17refers to (A)granite (B)surface (C)landscape (D)texture 17.Granite that has been found above ground has been (A)pushed up from below the crust by magma (B)produced during a volcanic explosion (C)gradually exposed due to erosion (D)pushed up by the natural shifting of the Earth 18.Which of the following is produced when magma cools rapidly?

(A)Plutonic rock (B)Crystal (C)Lava (D)Obsidian Questions 21-33 Although only 1person in 20in the Colonial period lived in a city,the cities had a disproportionate influence on the development of North America.They were at the cut ting edge of social change.It was in the cities that the elements that can be associated with modern capitalism first appeared -the use of money and commercial paper in place of barter,open competition in place of social deference and hierarchy,with an attendant rise in social disorder,and the appearance of factories using coat or water power in place of independent craftspeople working with hand tools."The cities predicted the future,"wrote historian Gary.B.Nash ,"even though they were but overgrown villages compared to the great urban centers of Europe,the Middle East and China." Except for Boston,whose population stabilized at about 16,000in 1760,cities grew by exponential leaps through the eighteenth century.In the fifteen years prior to the outbreak of the War for independence in 1775,more than 200,000immigrants arrived on North American shores This meant that a population the size of Boston was arriving every year,and most of it flowed into the port cities in the Northeast.Philadelphia"s population nearly doubted in those years,reaching about 30,000in 1774,New York grew at almost the same rate,reaching about 25,000by 1775. The quality of the hinterland dictated the pace of growth of the cities.The land surrounding Boston had always been poor farm country,and by the mid-eighteenth century it was virtually stripped of its timber.The available farmland was occupied,there was little in the region beyond the city to attract immigrants.New York and Philadelphia,by contrast,served a rich and fertile hinterland laced with navigable watercourses.Scots,Irish,and Germans landed in these cities and followed the rivers inland.The regions around the cities of New York and Philadelphia became the breadbaskets of North America,sending grain not only to other colonies but also to England and southern Europe,where crippling droughts in the late 1760"s created a whole new market. 21.Which of the following aspects of North America in the eighteenth century does the passage mainl y discuss? (A)The effects of war on the growth of cities (B)The growth and influence of cities (C)The decline of farming in areas surrounding cities (D)The causes of immigration to cities 22.Why does the author say that "the cities had a disproportionate influence on the development of North America "lines1-2"? (A)The influence of the cities was mostly negative (B)The populations of the cities were small,but their influence was great. (C)The cities were growing at a great rate. (D)Most people pretended to live in cities 23.The phrase "in place of "in line 5is closest in meaning to (A)connected to (B)in addition to (C)because of (D)instead of 24.The word "attendant"in line 6is closest in meaning to (A)avoidable (B)accompanying (C)unwelcome (D)unexpected 25.Which of the following is mentioned as an element of modern capitalism?

(A)They produced grain especially for making bread. (B)They stored large quantities of grain during periods of drought (C)They supplied grain to other parts of North America and other countries. (D)They consumed more grain than all the other regions of North America. Questions 34-44 Researchers in the field of psychology have found that one of the best ways to make an important decision,such as choosing a university to attend or a business to invest in,involves the utilization of a decision worksheet.Psychologists who study optimization compare the actual decisions made by people to theoretical ideal decisions to see how similar they are.Proponents of the worksheet procedure believe that it will yield optimal,that is ,the best decisions.Although there are several variations on the exact format that worksheets can take,they are all similar in their essential aspects.Worksheets require defining the problem in a clear and concise way and then listing all possible solutions to the problem.Next,the pertinent considerations that will be affected by each decision are listed,and the relative importance of each consideration or consequence is determined.Each consideration is assigned a numerical value to reflect its relative importance.A decision is mathematically calculated by adding these values together.The alternative with the highest number of points emerges as the best decision. Since most important problems are multifaceted,there are several alternatives to choose from,each with unique advantages and disadvantages.One of the benefits of a pencil and paper decision-making procedu
