Question 1-8 ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
With Robert Laurent and William Zorach, direct carving ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
enters into the story of modern sculpture in the United States. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
Direct carving - in which the sculptors themselves carve stone ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
or wood with mallet and chisel - must be recognized as someÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
-thing more than just a technique. Implicit in it is an aesthetic ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
principle as well: that the medium has certain qualities of beauty ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
and expressiveness with which sculptors must bring their ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
own aesthetic sensibilities into harmony. For example, some-ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
times the shape or veining in a piece of stone or wood suggests, ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
perhaps even dictates, not only the ultimate form, but ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
even the subject matter. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
The technique of direct carving was a break with the nineteenth-ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
century tradition in which the making of a clay model ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
was considered the creative act and the work was then turned ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
over to studio assistants to be cast in plaster or bronze or carved ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
in marble. Neoclassical sculptors seldom held a mallet or chisel ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
in their own hands, readily conceding that the assistants they ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
employed were far better than they were at carving the finished ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
marble. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
With the turn-of-the-century Crafts movement and the ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
discovery of nontraditional sources of inspiration, such as ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
wooden African figures and masks, there arose a new urge for ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
hands-on, personal execution of art and an interaction with the ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
medium. Even as early as the 1880's and 1890's, nonconformist ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
European artists were attempting direct carving. By ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
the second decade of the twentieth century, Americans - ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
Laurent and Zorach most notably - had adopted it as their primary ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
means of working. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
Born in France, Robert Laurent(1890-1970) was a prodigy ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
who received his education in the United States. In 1905 ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
he was sent to Paris as an apprentice to an art dealer, and in ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
the years that followed he witnessed the birth of Cubism, ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
discovered primitive art, and learned the techniques of wood-ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
carving from a frame maker. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
Back in New York City by 1910, Laurent began carving ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
pieces such as The Priestess, which reveals his fascination with ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
African, pre-Columbian, and South Pacific art. Taking a walnut ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
plank, the sculptor carved the expressive, stylized design.ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
It is one of the earliest examples of direct carving in American ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
sculpture. The plank's form dictated the rigidly frontal view ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
and the low relief. Even its irregular shape must have appealed ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
to Laurent as a break with a long-standing tradition that ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
required a sculptor to work within a perfect rectangle or square. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@

ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
Question 9-19 ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
Birds that feed in flocks commonly retire together into ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
roosts. The reasons for roosting communally are not always ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
obvious, but there are some likely benefits. In winter especially,ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
it is important for birds to keep warm at night and conserve ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
precious food reserves. One way to do this is to find a ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
sheltered roost. Solitary roosters shelter in dense vegetation or ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
enter a cavity - horned larks dig holes in the ground and ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
ptarmigan burrow into snow banks - but the effect of sheltering ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
is magnified by several birds huddling together in the ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
roosts, as wrens, swifts, brown creepers, bluebirds, and anisÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
do. Body contact reduces the surface area exposed to the cold ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
air, so the birds keep each other warm. Two kinglets huddling ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
together were found to reduce their heat losses by a quarter ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
and three together saved a third of their heat. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
The second possible benefit of communal roosts is that ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
they act as "information centers." During the day, parties of ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
birds will have spread out to forage over a very large area. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
When they return in the evening some will have fed well, but ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
others may have found little to eat. Some investigators have ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
observed that when the birds set out again next morning, ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
those birds that did not feed well on the previous day appear to ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
follow those that did. The behavior of common and lesser ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
kestrels may illustrate different feeding behaviors of similar ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
birds with different roosting habits. The common kestrel ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
hunts vertebrate animals in a small, familiar hunting ground, ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
whereas the very similar lesser kestrel feeds on insects overa ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
large area. The common kestrel roosts and hunts alone, but ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
the lesser kestrel roosts and hunts in flocks, possibly so one ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
bird can learn from others where to find insect swarms. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
Finally, there is safety in numbers at communal roosts ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
since there will always be a few birds awake at any given ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
moment to give the alarm. But this increased protection is partially ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
counteracted by the fact that mass roosts attract predators and ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
are especially vulnerable if they are on the ground. Even those ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
in trees can be attacked by birds of prey. The birds on the ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
edge are at greatest risk since predators find it easier to catch ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
small birds perching at the margins of the roost. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@

States ate most foods only in season. Drying, smoking, and ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
salting could preserve meat for a short time, but the availability ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
of fresh meat, like that of fresh milk, was very limited; ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
there was no way to prevent spoilage. But in 1810 a French ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
inventor named Nicolas Appert developed the cooking-and-sealingÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
process of canning. And in the 1850's an American ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
named Gail Borden developed a means of condensing and preserving ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
milk. Canned goods and condensed milk became more ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
common during the 1860's, but supplies remained low because ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
cans had to be made by hand. By 1880, however, inventors ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
had fashioned stamping and soldering machines that mass-produced ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
cans from tinplate. Suddenly all kinds of food could be ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
preserved and bought at all times of the year. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
Other trends and inventions had also helped make it possible ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
for Americans to vary their daily diets. Growing urban ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
populations created demand that encouraged fruit and vegetable ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
farmers to raise more produce. Railroad refrigerator cars ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
enabled growers and meat packers to ship perishables great ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
distances and to preserve them for longer periods. Thus, by the ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
1890's, northern city dwellers could enjoy southern and ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
western strawberries, grapes, and tomatoes, previously available ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
for a month at most, for up to six months of the year. In ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
addition, increased use of iceboxes enabled families to store ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
perishables. An easy means of producing ice commercially had ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
been invented I the 1870's, and by 1900 the nation had ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
more than two thousand commercial ice plants, most of which ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
made home deliveries. The icebox became a fixture in most ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
homes and remained so until the mechanized refrigerator ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
replaced it in the 1920's and 1930's. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
Almost everyone now had a more diversified diet. Some ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
people continued to eat mainly foods that were heavy in starches ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
or carbohydrates, and not everyone could afford meat. Never-ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
theless, many families could take advantage of previously ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
unavailable fruits, vegetables, and dairy products to achieve ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@

Question 31-38 ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
The ability of falling cats to right themselves in midair ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
and land on their feet has been a source of wonder for ages. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
Biologists long regarded it as an example of adaptation by ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
natural selection, but for physicists it bordered on the miraculous. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
Newton's laws of motion assume that the total amount of spin ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
of a body cannot change unless an external torque speeds it up ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
or slows it down. If a cat has no spin when it is released and ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
experiences no external torque, it ought not to be able to twist ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
around as it falls. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
In the speed of its execution, the righting of a tumbling ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
cat resembles a magician's trick. The gyrations of the cat in ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
midair are too fast for the human eye to follow, so the process ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
is obscured. Either the eye must be speeded up, or the cat's ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
fall slowed down for the phenomenon to be observed. A century ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
ago the former was accomplished by means of high-speed ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
photography using equipment now available in any pharmacy. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
But in the nineteenth century the capture on film of a falling ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
cat constituted a scientific experiment. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
The experiment was described in a paper presented to the ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
Paris Academy in 1894. Two sequences of twenty photographs ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
each, one from the side and one from behind, show a ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
white cat in the act of righting itself. Grainy and quaint ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
though they are, the photos show that the cat was dropped ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
upside down, with no initial spin, and still landed on its feetÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
Careful analysis of the photos reveals the secret. As the catÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
rotates the front of its body clockwise, the rear and tail twist ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
counterclockwise, so that the total spin remains zero, in perfect ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
accord with Newton's laws. Halfway down, the cat ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
pulls in its legs before reversing its twist and then extends ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
them again, with the desired end result. The explanation was ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
that while no body can acquire spin without torque, a flexible ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
one can readily change its orientation, or phase. Cats know ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
this instinctively, but scientists could not be sure how it ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
happened until they increased the speed of their perceptions a ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@

Question 39-50
ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
The changing profile of a city in the United States is apparent ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
in the shifting definitions used by the United States Bureau ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
of the Census. In 1870 the census officially distinguished ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
the nation's "urban" from its "rural" population for the first ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
time. "Urban population" was defined as persons living in ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
towns of 8,000 inhabitants or more. But after 1900 it meant ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
persons living in incorporated places having 2,500 or more ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
inhabitants. ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
Then, in 1950 the Census Bureau radically changed its ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
definition of "urban" to take account of the new vagueness of ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
city boundaries. In addition to persons living in incorporated ÝÁÏPÊÈu³Øforum.liuxuehome.comÐHOBÖ#BhÑ@
