单选题Universally, men tend to score higher on certain specialized skills, such as spatial awareness. In the real world, that means they might be better at reading maps or navigating. Women score higher in terms of language development and emotional intelligence. But most experts agree there is no real, important overall difference when it comes to gender and intelligence. What do most expels think of the relationship between gender and intelligence?A. There is a close relationship between gender and intelligence.B. There is no important link between gender and intelligence.C. Gender and intelligence do not relate to each other at all.D. Males are usually more intelligent than females.

Urban Rainforest On the west
side of the island of Manhattan in New York City, tree by tree, leaf by leaf, a
2,500 square foot sector of the Central African Republic's Dzanga Ndoki
Rainforest has been transported to, or recreated at, the American Museum of
Natural History's new hall of biodiversity. When the hall opens this May,
visitors will visit one of the world's biggest and most accurate reproduction of
one of nature's most threatened creations. To bring the
rainforest to New York, a team of nearly two dozen scientists—the largest
collecting expedition the museum has ever organized for an exhibit—spent five
weeks in the African rainforest collecting soil, plants, and leaves; recording
and documenting species; studying trees; shooting videotape and still photos;
and interviewing local people. "This area has been explored very little," says
Hoel Cracraft who estimates that the museum will eventually collect 150 to 180
mammals, more than 300 species of birds, hundreds of butterflies, and hundreds
of thousands, if not millions, of organisms. The exhibition may even have
produced a special prize—scientists suspect they have uncovered several new
species. To give the forest a sense of realness, the back wall
of the exhibit is an enormous videoscreen, sounds will come out from hidden
speakers, and plans even call for forest smells. Computer controls will vary the
effects so that no two walkthroughs will ever be exactly the same.
After the team returned to New York, the forest was reproduced with the
help of the computer. Computer Modelling Programmes plotted distances and
special relationships. Artists studied photos and brought what they saw to life.
Plaster trees were made. Recreated animals began to stand in the rainforest of
the hall. Flying creatures will hang from the ceiling. The light in the
forest—one of the exhibit's cleverest recreations—will seem real. Long tube
lights will have the correct colour and temperature to produce a natural effect.
The plants and animals exhibited throughout the hall exist naturally in a
perfect balance—remove one, and the whole is imperfect if not endangered. The
exhibit is proof to the hope that the world's rainforests will never exist
solely as a carefully preserved artifact.

{{B}}Male and Female Pilots Cause Accidents Differently{{/B}}
Male pilots flying general aviation (private) aircraft in the United
States are more likely to crash due to inattention or flawed decision-making.
While female pilots are more likely to crash from mishandling the aircraft.
These are the results of a study by researchers at the Johns Hopkins University
Bloomberg School of Public Health. The study identifies the
differences between male and female pilots in terms of circumstances of the
crash and the type of pilots error involved. "Crashes of general aviation
aircraft account for 85 percent of all aviation deaths in the United States. The
crash rate for male pilots, as for motor vehicle drivers, exceeds that of
crashes of female pilots," explains Susan P. Baker, MPH, professor of health
policy and management at the Bloomberg School of Public Health. "Because pilot
youth and inexperience are established contributors to aviation crashes, we
focused on only mature pilots, to determine the gender differences in the
reasons for the crash." The researchers extracted data for this
study from a large research project on pilot aging and flight safety. The data
were gathered from general aviation crashes of airplanes and heIicopters between
1983 and 1997, involving 144 female pilots and 267 male pilots aged 40-63.
Female pilots were matched with male pilots in a 1:2 ratio, by age, classes of
medical and pilot certificates, state or area of crash, and year of crash. Then
the circumstances of the crashes and the pilot error involved were categorized
and coded without knowledge of pilot gender. The researchers
found that loss of control on landing or takeoff was the most common
circumstance for both sexes, leading to 59 percent of female pi.lots' crashes
and 36 percent of males'. Experiencing mechanical failure, running out of fuel,
and land!ng the plane with the landing gear up were among the factors more
likely with males, while stalling was more likely with females.
The majority of the crashes — 95 percent for females and 88 percent for
males — involved at least one type of pilot error. Mishandling aircraft kinetics
was the most common error for both sexes, but was more common among females
(accounting for 81 percent of the crashes) than males (accounting for 48
percent). Males, however, appeared more likely to be guilty of poor
decision-making, risk-taking, and inattentiveness, examples of which include
misjudging weather and visibility or flying an aircraft with a known defect.
Females, though more likely to mishandle or lose control of the aircraft, were
generally more careful than their male counterparts.
