Questions 1-10
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞThe word laser was coined as an acronym for Light
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞAmplification by the Stimulated Emission of Radiation. Ordinary
äú&decTÝforum.pre-mbaclub.com§ÿ5Þlight, from the Sun or a light bulb, is emitted spontaneously,
äú&decTÝforum.pre-mbaclub.com§ÿ5Þwhen atoms or molecules get rid of excess energy by themselves,
äú&decTÝforum.pre-mbaclub.com§ÿ5Þwithout any outside intervention. Stimulated emission
äú&decTÝforum.pre-mbaclub.com§ÿ5Þis different because it occurs when an atom or molecule holding
äú&decTÝforum.pre-mbaclub.com§ÿ5Þonto excess energy has been stimulated to emit it as light.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞAlbert Einstein was the first to suggest the existence of
äú&decTÝforum.pre-mbaclub.com§ÿ5Þstimulated emission in a paper published in 1917. However ,
äú&decTÝforum.pre-mbaclub.com§ÿ5Þfor many years physicists thought that atoms and molecules
äú&decTÝforum.pre-mbaclub.com§ÿ5Þalways were much more likely to emit light spontaneously and
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthat stimulated emission thus always would be much weaker.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞIt was not until after the Second World War that physicists
äú&decTÝforum.pre-mbaclub.com§ÿ5Þbegan trying to make stimulated emission dominate. They
äú&decTÝforum.pre-mbaclub.com§ÿ5Þsought ways by which one atom or molecule could stimulate
äú&decTÝforum.pre-mbaclub.com§ÿ5Þmany other to emit light , amplifying it to much higher
äú&decTÝforum.pre-mbaclub.com§ÿ5Þpowers.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞThe first to succeed was Charles H.Townes, then at
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞColombia University in New York . Instead of working with
äú&decTÝforum.pre-mbaclub.com§ÿ5Þlight , however, he worked with microwaves, which have a
äú&decTÝforum.pre-mbaclub.com§ÿ5Þmuch longer wavelength, and built a device he called a
äú&decTÝforum.pre-mbaclub.com§ÿ5Þ"maser" for Microwave Amplification by the Stimulated
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞEmission of Radiation. Although he thought of the key idea in
äú&decTÝforum.pre-mbaclub.com§ÿ5Þ1951, the first maser was not completed until a couple of years
äú&decTÝforum.pre-mbaclub.com§ÿ5Þlater. Before long, many other physicists were building masers
äú&decTÝforum.pre-mbaclub.com§ÿ5Þand trying to discover how to produce stimulated emission at
äú&decTÝforum.pre-mbaclub.com§ÿ5Þeven shorter wavelength.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞThe key concepts emerged about 1957. Townes and
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞArthur Schawlow, then at Bell Telephone Laboratories, wrote
äú&decTÝforum.pre-mbaclub.com§ÿ5Þa long paper outlining the conditions needed to amplify
äú&decTÝforum.pre-mbaclub.com§ÿ5Þstimulated emission of visible light waves. At about the same time,
äú&decTÝforum.pre-mbaclub.com§ÿ5Þsimilar ideas crystallized in the mind of Gordon Gould, then a
äú&decTÝforum.pre-mbaclub.com§ÿ5Þ37- year-old graduate student at Columbia, who wrote them
äú&decTÝforum.pre-mbaclub.com§ÿ5Þdown in a series of notebooks. Townes and Schawlow
äú&decTÝforum.pre-mbaclub.com§ÿ5Þpublished their ideas in a scientific journal, Physical Review
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞLetter, but Gould filed a patent application. Three decades later,
äú&decTÝforum.pre-mbaclub.com§ÿ5Þpeople still argue about who deserves the credit for the concept
äú&decTÝforum.pre-mbaclub.com§ÿ5Þof the laser.

äú&decTÝforum.pre-mbaclub.com§ÿ5ÞQuestions 11-21
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞPanel painting, common in thirteenth -and fourteenth
äú&decTÝforum.pre-mbaclub.com§ÿ5Þ-century Europe , involved a painstaking , laborious process.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞWooden planks were joined, covered with gesso to prepare the
äú&decTÝforum.pre-mbaclub.com§ÿ5Þsurface for painting , and then polished smooth with special
äú&decTÝforum.pre-mbaclub.com§ÿ5Þtools. On this perfect surface, the artist would sketch a
äú&decTÝforum.pre-mbaclub.com§ÿ5Þcomposition with chalk, refine it with inks, and then begin the
äú&decTÝforum.pre-mbaclub.com§ÿ5Þdeliberate process of applying thin layers of egg tempera paint
äú&decTÝforum.pre-mbaclub.com§ÿ5Þ(egg yolk in which pigments are suspended) with small brushes.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞThe successive layering of these meticulously applied paints
äú&decTÝforum.pre-mbaclub.com§ÿ5Þproduced the final, translucent colors.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞBackgrounds of gold were made by carefully applying
äú&decTÝforum.pre-mbaclub.com§ÿ5Þsheets of gold leaf, and then embellishing of decorating the
äú&decTÝforum.pre-mbaclub.com§ÿ5Þgold leaf by punching it with a metal rod on which a pattern
äú&decTÝforum.pre-mbaclub.com§ÿ5Þhad been embossed. Every step in the process was slow and
äú&decTÝforum.pre-mbaclub.com§ÿ5Þdeliberate . The quick-drying tempera demanded that the artist
äú&decTÝforum.pre-mbaclub.com§ÿ5Þknow exactly where each stroke be placed before the brush met
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthe panel, and it required the use of fine brushes. It was,
äú&decTÝforum.pre-mbaclub.com§ÿ5Þtherefore , an ideal technique for emphasizing the hard linear
äú&decTÝforum.pre-mbaclub.com§ÿ5Þedges and pure, fine areas of color that were so much a part of
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthe overall aesthetic of the time. The notion that an artist
äú&decTÝforum.pre-mbaclub.com§ÿ5Þcould or would dash off an idea in a fit of spontaneous
äú&decTÝforum.pre-mbaclub.com§ÿ5Þinspiration was completely alien to these deliberately produced works.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞFurthermore, making these paintings was so time-consuming
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthat it demanded assistance. All such work was done
äú&decTÝforum.pre-mbaclub.com§ÿ5Þby collective enterprise in the workshops. The painter or
äú&decTÝforum.pre-mbaclub.com§ÿ5Þmaster who is credited with having created painting may have
äú&decTÝforum.pre-mbaclub.com§ÿ5Þdesigned the work and overseen its production, but it is highly
äú&decTÝforum.pre-mbaclub.com§ÿ5Þunlikely that the artist's hand applied every stroke of the
äú&decTÝforum.pre-mbaclub.com§ÿ5Þbrush. More likely, numerous assistants, who had been
äú&decTÝforum.pre-mbaclub.com§ÿ5Þtrained to imitate the artist's style, applied the paint. The carpenter's shop probably provided the frame and perhaps supplied
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthe panel, and yet another shop supplied the gold. Thus,
äú&decTÝforum.pre-mbaclub.com§ÿ5Þnot only many hands , but also many shops were involved in
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthe final product.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞIn spite of problems with their condition, restoration,
äú&decTÝforum.pre-mbaclub.com§ÿ5Þand preservation many panel paintings have survived, and
äú&decTÝforum.pre-mbaclub.com§ÿ5Þtoday many of them are housed in museum collections.

äú&decTÝforum.pre-mbaclub.com§ÿ5ÞQuestions 22-32
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞCrows are probably the most frequently met and easily
äú&decTÝforum.pre-mbaclub.com§ÿ5Þidentifiable members of the native fauna of the United States.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞThe great number of tales, legends, and myths about these
äú&decTÝforum.pre-mbaclub.com§ÿ5Þbirds indicates that people have been exceptionally interested in
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthem for a long time. On the other hand, when it comes to
äú&decTÝforum.pre-mbaclub.com§ÿ5Þsubstantive -- particularly behavioral -- information, crows
äú&decTÝforum.pre-mbaclub.com§ÿ5Þare less well known than many comparably common species
äú&decTÝforum.pre-mbaclub.com§ÿ5Þand, for that matter, not a few quite uncommon ones: the
äú&decTÝforum.pre-mbaclub.com§ÿ5Þendangered California condor, to cite one obvious example.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞThere are practical reasons for this.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞCrows are notoriously poor and aggravating subjects for
äú&decTÝforum.pre-mbaclub.com§ÿ5Þfield research. Keen observers and quick learners, they are
äú&decTÝforum.pre-mbaclub.com§ÿ5Þastute about the intentions of other creatures, including
äú&decTÝforum.pre-mbaclub.com§ÿ5Þresearchers, and adept at avoiding them. Because they are so
äú&decTÝforum.pre-mbaclub.com§ÿ5Þnumerous, active, and monochromatic, it is difficult to
äú&decTÝforum.pre-mbaclub.com§ÿ5Þdistinguish one crow from another. Bands, radio transmitters, or
äú&decTÝforum.pre-mbaclub.com§ÿ5Þother identifying devices can be attached to them , but this of
äú&decTÝforum.pre-mbaclub.com§ÿ5Þcourse requires catching live crows, who are among the wariest
äú&decTÝforum.pre-mbaclub.com§ÿ5Þand most untrappable of birds.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞTechnical difficulties aside , crow research is daunting
äú&decTÝforum.pre-mbaclub.com§ÿ5Þbecause the ways of these birds are so complex and various.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞAs preeminent is generalists, members of this species
äú&decTÝforum.pre-mbaclub.com§ÿ5Þingeniously exploit a great range of habitats and resources, and
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthey can quickly adjust to changes in their circumstances.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞBeing so educable, individual birds have markedly different interests
äú&decTÝforum.pre-mbaclub.com§ÿ5Þand inclinations, strategies and scams. For example, one
äú&decTÝforum.pre-mbaclub.com§ÿ5Þpet crow learned how to let a dog out of its kennel by pulling
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthe pin on the door. When the dog escaped, the bird went into
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthe kennel and ate its food.
äú&decTÝforum.pre-mbaclub.com§ÿ5Þ22.What is the main topic of the passage?

äú&decTÝforum.pre-mbaclub.com§ÿ5ÞQuestions 33-41
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞIn the early days of the United States, postal charges
äú&decTÝforum.pre-mbaclub.com§ÿ5Þwere paid by the recipient and Charges varied with the
äú&decTÝforum.pre-mbaclub.com§ÿ5Þdistance carried. In 1825, the United States Congress permitted
äú&decTÝforum.pre-mbaclub.com§ÿ5Þlocal postmasters to give letters to mail carriers for home
äú&decTÝforum.pre-mbaclub.com§ÿ5Þdelivery, but these carriers received no government salary and their
äú&decTÝforum.pre-mbaclub.com§ÿ5Þentire compensation depended on what they were paid by the
äú&decTÝforum.pre-mbaclub.com§ÿ5Þrecipients of individual letters.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞIn 1847 the United States Post Office Department
äú&decTÝforum.pre-mbaclub.com§ÿ5Þadopted the idea of a postage stamp, which of course simplified
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthe payment for postal service but caused grumbling by those
äú&decTÝforum.pre-mbaclub.com§ÿ5Þwho did not like to prepay. Besides, the stamp covered only
äú&decTÝforum.pre-mbaclub.com§ÿ5Þdelivery to the post office and did not include carrying it to a
äú&decTÝforum.pre-mbaclub.com§ÿ5Þprivate address. In Philadelphia, for example, with a population
äú&decTÝforum.pre-mbaclub.com§ÿ5Þof 150,000, people still had to go to the post office to get
äú&decTÝforum.pre-mbaclub.com§ÿ5Þtheir mail. The confusion and congestion of individual citizens
äú&decTÝforum.pre-mbaclub.com§ÿ5Þlooking for their letters was itself enough to discourage use of
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthe mail. It is no wonder that, during the years of these
äú&decTÝforum.pre-mbaclub.com§ÿ5Þcumbersome arrangements, private letter-carrying and express
äú&decTÝforum.pre-mbaclub.com§ÿ5Þbusinesses developed. Although their activities were only
äú&decTÝforum.pre-mbaclub.com§ÿ5Þsemilegal, they thrived, and actually advertised that between
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞBoston and Philadelphia they were a half-day speedier than the
äú&decTÝforum.pre-mbaclub.com§ÿ5Þgovernment mail. The government postal service lost volume
äú&decTÝforum.pre-mbaclub.com§ÿ5Þto private competition and was not able to handle efficiently
äú&decTÝforum.pre-mbaclub.com§ÿ5Þeven the business it had.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞFinally, in 1863, Congress provided that the mail carriers
äú&decTÝforum.pre-mbaclub.com§ÿ5Þwho delivered the mail from the post offices to private addresses
äú&decTÝforum.pre-mbaclub.com§ÿ5Þshould receive a government salary, and that there should
äú&decTÝforum.pre-mbaclub.com§ÿ5Þbe no extra charge for that delivery. But this delivery service
äú&decTÝforum.pre-mbaclub.com§ÿ5Þwas at first confined to cities, and free home delivery became a
äú&decTÝforum.pre-mbaclub.com§ÿ5Þmark of urbanism. As late as 1887, a town had to have 10,000
äú&decTÝforum.pre-mbaclub.com§ÿ5Þpeople to be eligible for free home delivery. In 1890, of
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthe 75 million people in the United States, fewer than 20
äú&decTÝforum.pre-mbaclub.com§ÿ5Þmillion had mail delivered free to their doors. The rest, nearly
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthree-quarters of the population, still received no mail unless
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthey went to their post office.

äú&decTÝforum.pre-mbaclub.com§ÿ5ÞQuestions 42-50
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞArchaeology has long been an accepted tool for studying
äú&decTÝforum.pre-mbaclub.com§ÿ5Þprehistoric cultures. Relatively recently the same techniques
äú&decTÝforum.pre-mbaclub.com§ÿ5Þhave been systematically applied to studies of the more
äú&decTÝforum.pre-mbaclub.com§ÿ5Þimmediate past. This has been called "historical archaeology," a
äú&decTÝforum.pre-mbaclub.com§ÿ5Þterm that is used in the United States to refer to any
äú&decTÝforum.pre-mbaclub.com§ÿ5Þarchaeological investigation into North American sites that postdate
äú&decTÝforum.pre-mbaclub.com§ÿ5Þthe arrival of Europeans.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞBack in the 1930's and 1940's, when building restoration
äú&decTÝforum.pre-mbaclub.com§ÿ5Þwas popular, historical archaeology was primarily a tool of
äú&decTÝforum.pre-mbaclub.com§ÿ5Þarchitectural reconstruction. The role of archaeologists was to
äú&decTÝforum.pre-mbaclub.com§ÿ5Þfind the foundations of historic buildings and then take a back
äú&decTÝforum.pre-mbaclub.com§ÿ5Þseat to architects.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞThe mania for reconstruction had largely subsided by the
äú&decTÝforum.pre-mbaclub.com§ÿ5Þ1950's and 1960's. Most people entering historical archaeology
äú&decTÝforum.pre-mbaclub.com§ÿ5Þduring this period came out of university anthropology de-
äú&decTÝforum.pre-mbaclub.com§ÿ5Þpartments., where they had studied prehistoric cultures. They
äú&decTÝforum.pre-mbaclub.com§ÿ5Þwere, by training, social scientists, not historians, and their
äú&decTÝforum.pre-mbaclub.com§ÿ5Þwork tended to reflect this bias. The questions they framed
äú&decTÝforum.pre-mbaclub.com§ÿ5Þand the techniques they used were designed to help them
äú&decTÝforum.pre-mbaclub.com§ÿ5Þunderstand, as scientists, how people behaved. But because they
äú&decTÝforum.pre-mbaclub.com§ÿ5Þwere treading on historical ground for which there was often
äú&decTÝforum.pre-mbaclub.com§ÿ5Þextensive written do cumentation and because their own knowledge
äú&decTÝforum.pre-mbaclub.com§ÿ5Þof these periods was usually limited, their contributions
äú&decTÝforum.pre-mbaclub.com§ÿ5Þto American history remained circumscribed. Their reports,
äú&decTÝforum.pre-mbaclub.com§ÿ5Þhighly technical and sometimes poorly written, went unread.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞMore recently, professional archaeologists have taken
äú&decTÝforum.pre-mbaclub.com§ÿ5Þover. These researchers have sought to demonstrate that their
äú&decTÝforum.pre-mbaclub.com§ÿ5Þwork can be a valuable tool not only of science but also of
äú&decTÝforum.pre-mbaclub.com§ÿ5Þhistory, providing fresh insights into the daily lives of ordinary
äú&decTÝforum.pre-mbaclub.com§ÿ5Þpeople whose existences might not otherwise be so well
äú&decTÝforum.pre-mbaclub.com§ÿ5Þdocumented. This newer emphasis on archaeology as social history
äú&decTÝforum.pre-mbaclub.com§ÿ5Þhas shown great promise, and indeed work done in this area
äú&decTÝforum.pre-mbaclub.com§ÿ5Þhas lead to a reinterpretation of the United States past.
äú&decTÝforum.pre-mbaclub.com§ÿ5ÞIn Kingston, New York, for example, evidence has
äú&decTÝforum.pre-mbaclub.com§ÿ5Þuncovered that indicates that English goods were being
äú&decTÝforum.pre-mbaclub.com§ÿ5Þsmuggled into that city at a time when the Dutch supposedly
äú&decTÝforum.pre-mbaclub.com§ÿ5Þcontrolled trading in the area. And in Sacramento an
äú&decTÝforum.pre-mbaclub.com§ÿ5Þexcavation at site of a fashionable nineteenth-century hotel
äú&decTÝforum.pre-mbaclub.com§ÿ5Þrevealed that garbage had been stashed in the building's base-
äú&decTÝforum.pre-mbaclub.com§ÿ5Þment despite sanitation laws to the contrary.
