题目：

Heavy snow fall in the Sierra Nevada Mountains is usually preceded by subzero temperatures in northwestern Canada. When snow fall is high in Canada’s northwestern provinces, the same storm typically produces heavy snows in the Sierra Nevadas. Therefore, subzero temperatures cause winter snow storms to rebuild as they move down from Canada to the Sierra Nevadas.
Which selection contains the same type flaw as that contained in the passage above?

选项:

A、A. Professional golfers tend to have lean builds. Therefore, professional golfers typically have healthy eating habits.
B、B. People tend to write larger when they use wide-ruled notebook paper than when they use narrow-ruled paper. Therefore, people write more neatly on the wide-ruled paper.
C、C. Students who participate in debate in high school often end up as trial lawyers. Therefore, participating in high school debate must somehow influence students to attend law school.
D、D. During the hottest part of the day, song birds do not visit unshaded feeders. Therefore, song birds must visit the feeders before dawn.

题目：

Researchers believe that we will ultimately be able to explain all "psychic" phenomena. Achieving this goal requires knowledge of how mental images are "sent" and "received" over distance and how senders and receivers interact at a biological level. At present, there is a substantial amount of fundamental knowledge about receiving images and sending images. Thus, as researchers claim, psychic phenomena will soon be explainable.
Which one of the following indicates an error in the reasons in the passage?

选项:

A、A. The conclusion contradicts researchers.
B、B. The passage fails to describe what is currently known about senders and receivers.
C、C. The passage does not indicate that any knowledge has been achieved about how senders and receivers interact at a biological level.
D、D. The argument does not indicate whether this information will be useful.
E、E. The passage is not specific about what psychic phenomena are being researched.

The following appeared in the editorial section of a campus newspaper
 
"Because occupancy rates for campus housing fell during the last academic year, so did housing revenues. To solve the problem, campus housing officials should reduce the number of available housing units, thereby increasing the occupancy rates. Also, to keep students from choosing to live off-campus, housing officials should lower the rents, thereby increasing demand."

题目：

Between 1980 and 2000 the sea otter population of the Aleutian Islands declined precipitously. There were no signs of disease or malnutrition, so there was probably an increase in the number of otters being eaten by predators. Orcas will eat otters when seals, their normal prey, are unavailable, and the Aleutian Islands seal population declined dramatically in the 1980s. Therefore, orcas were most likely the immediate cause of the otter population decline.

Which of the following, if true, most strengthens the argument?

选项:

A、The population of sea urchins, the main food of sea otters, has increased since the sea otter population declined.
B、Seals do not eat sea otters, nor do they compete with sea otters for food.
C、Most of the surviving sea otters live in a bay that is inaccessible to orcas.
D、The population of orcas in the Aleutian Islands has declined since the 1980s.
E、An increase in commercial fishing near the Aleutian Islands in the 1980s caused a slight decline in the population of the fish that seals use for food.

题目：

Wind farms, which generate electricity using arrays of thousands of wind-powered turbines, require vast expanses of open land.  County X and County Y have similar terrain, but the population density of County X is significantly higher than that of County Y.  Therefore, a wind farm proposed for one of the two counties should be built in County Y rather than in County X.
 
Which of the following, if true, most seriously weakens the planner's argument?

选项:

A、County X and County Y are adjacent to each other, and both are located in the windiest area of the state.
B、The total population of County Y is substantially greater than that of County X.
C、Some of the electricity generated by wind farms in County Y would be purchased by users outside the county.
D、Wind farms require more land per unit of electricity generated than does any other type of electrical-generation facility.
E、Nearly all of County X's population is concentrated in a small part of the county, while County Y's population is spread evenly throughout the country.

题目：

Chaco Canyon, a settlement of the ancient Anasazi culture in North America, had massive buildings. It must have been a major Anasazi center. Analysis of wood samples shows that some of the timber for the buildings came from the Chuska and San Mateo mountains, 50 miles from Chaco Canyon. Only a major cultural center would have the organizational power to import timber from 50 miles away.

Art historian: Unlike many artistic traditions that sought to depict plants native to the local area in a seasonally appropriate way (for example, depicting scenes of spring with the plants in the appropriate stages of development for that season), seventeenth-century Dutch artists specializing in flower paintings almost exclusively chose to depict exotic species of flowers from outside the local area. Painting such species was worthwhile primarily because the art-buying public had developed a strong preference for images of the exotic. The great botanical centers of the time gave the artists direct access to such flowers, which the artists would freely combine in a single painting, regardless of whether the combined species occurred together in the wild, and depicted each in full bloom, regardless of whether those species bloomed at the same time in nature.

Statement: The art historian makes the point that the species of flowers these Dutch artists chose to paint were 1 largely because the species were 2 .

Select for 1 and for 2 the options that complete the statement so that it is most strongly supported by the information provided. Make only two selections, one in each column.

Tiger beetles are such fast runners that they can capture virtually any nonflying insect.  However, when running toward an insect, the beetles intermittently stop, and then, a moment later, resume their attack.  Perhaps they cannot maintain their pace and must pause for a moment's rest; but an alternative hypothesis is that while running tiger beetles are unable to process the resulting rapidly changing visual information, and so quickly go blind and stop.

What was the dealer's approximate profit or loss as a percent of the dealer's initial cost for the 60 cameras?
