Scientists have long warned that some level of global warming is a done deal—due in large part to heat-trapping greenhouse gases humans already have pumped skyward. Now, however, researchers are fleshing out how much future warming and sea-level rise the world has triggered. The implicit message: "We can’t stop this, so how do we live with it" says Thomas Wigley, a climate researcher at NCAR.
One group, led by Gerald Meehl at NCAR, used two state-of-the-art climate models to explore what could happen if the world had held atmospheric concentrations of greenhouse gases steady since 2000. The results: Even if the world had slammed on the brakes five years ago, global average temperatures would rise by about 1 degree Fahrenheit by the end of the 21st century. Sea levels would rise by another 4 inches over 20th-century increases. Rising sea-levels would continue well beyond 2100, even without adding water from melting glaciers and i
A. getting worse because of a culture bias.
B. caused by the rise of the sea level.
C. people have to live with.
D. we don't need to worry about in the future.

Car makers have long used sex to sell their products. Recently, how. ever, both BMW and Renault have based their latest European marketing campaigns around the icon of modern biology.
BMW’s campaign, which launches its new 3-series sports saloon in Britain and Ireland, shows the new creation and four of its earlier versions zigzagging around a landscape made up of giant DNA sequences, with a brief explanation that DNA is the molecule responsible for the inheritance of such features as strength, power and intelligence. The Renault offering, which promotes its existing Laguna model, employs evolutionary theory even more explicitly. The company’s television commercials intersperse clips of the car with scenes from a lecture by Steve Jones, a professor of genetics at University of London.
BMW’s campaign is intended to convey the idea of development allied to heritage. The latest product, in other words, should be viewed as the n
A. poverty,
B. extinction.
C. revolution.
D. evolution.

People have wondered for a long time how their personalities and behaviors are formed, h is not easy to explain why one person is intelligent and another is not, or why one is cooperative and another is competitive.
Social scientists are, of course, extremely interested in these types of questions. They want to explain why we possess certain characteristics and exhibit certain behaviors. There are no clear answers yet, but two distinct schools of thought on the matter have developed. As one might expect, the two approaches are very different from one another, and there is a great deal of debate between proponents of each theory. The controversy is often referred to as "nature/nurture".
Those who support the "nature" side of the conflict believe that our personalities and behavior patterns are largely determined by biological and genetic factors. That our environment has little, if anything, to do with our abilities, charac
A. supports the nature theory
B. supports the nurture theory
C. believes both are completely wrong
D. thinks that the correct explanation of human behavior will take ideas from both theories
