The weather forecast says it will be cloudy with a slight（） of rain later tonight.

A:effect B:sense C:change D:chance

Climatic conditions are delicately adjusted to the composition of the Earth’s atmosphere. If there were a change in the atmosphere--for example, in the relative proportions of atmospheric gases"-the climate would probably change also. A slight increase in water vapor, for instance, would increase the heat-retaining capacity of the atmosphere and would lead to a rise in global temperatures. In contrast, a large increase in water vapor would increase the thickness and extent of the cloud layer, reducing the amount of solar energy reaching the Earth’s surface.
The level of carbon dioxide in the atmosphere has an important effect on climatic change. Most of the Earth’s incoming energy is short-wavelength radiation, which tends to pass through atmospheric carbon dioxide easily. The Earth, however, reradiates much of the received energy as long-wavelength radiation, which carbon dioxide absorbs and then remits toward the Earth. This phenomenon, known as the greenhouse effect, can result in an increase in the surface temperature of a planet. An extreme example of the effect is shown by Venus, a planet covered by heavy clouds composed mostly of carbon dioxide, whose surface temperatures have been measured at 43012. If the carbon dioxide content of the atmosphere is reduced, the temperature falls. According to one respectable theory, if the atmospheric carbon dioxide concentration were halved, the Earth would become completely covered with ice. Another equally respectable theory, however, states that a halving of the carbon dioxide concentration would lead only to reduction in global temperatures of 312.
If, because of an increase in forest fires or volcanic activity, the carbon dioxide content of the atmosphere increased, a warmer climate would be produced. Plant growth, which relies on both the warmth and the availability of carbon dioxide, would probably increase. As a consequence, plants would use more and more carbon dioxide. Eventually carbon dioxide levels would diminish and the climate, in turn, would become cooler. With reduced temperatures many plants would die; carbon dioxide would thereby be returned to the atmosphere and gradually the temperature would rise again. Thus, if this process occurred, there might be a long-term oscillation in the amount of carbon dioxide present in the atmosphere, with regular temperature increases and decreases of a set magnitude.
Some climatologists argue that the burning of fossil fuels has raised the level of carbon dioxide in the atmosphere and has caused a global temperature increase of at least 1 C. But a supposed global temperature rise of 112 may in reality be only several regional temperature increases, restricted to areas where there are many meteorological stations and mused simply by shifts in the pattern of atmospheric circulation. Other areas, for example, the Southern Hemisphere Oceanic Zone, may be experiencing an equivalent temperature decrease that is unrecognized because of the shortage of meteorological recording stations.
The passage suggests that a large decrease in the amount of carbon dioxide in the atmosphere would result in______.

A:at least a slight decrease in global temperatures B:at the most a slight increase in short-wavelength radiation reaching the Earth C:a slight long-term increase in global temperatures D:a large long-term increase in the amount of volcanic activity

Many video games feature an invincibility power-up that makes the players impervious to damage, at least for a while. As the economic crisis hit in late 2008, some said the same about the industry itself. The theory went that sales of video games, which had been strong in 2008, would also be strong in 2009, because games are a relatively cheap form of entertainment that let people escape from gloomy economic reality.
At first glance the sales figures seem to debunk the idea that video games are recession-proof. In June 2009, for example, sales of games in America were 31% lower than in June 2008, according to NPD, a market-research firm. In July sales were down 26% , the fifth successive monthly decline. But the year ended with a record-breaking December, as people bought consoles and games for Christmas. Globally, says Piers Harding-Rolls of Screen Digest, a consuhancy, sales of games were down by 6.3% in 2009. The number of Nintendo Win and Microsoft Xbox 360 consoles sold was flat in 2009 ; sales of Sow’s PlayStation 3 were up by 22% after a price cut.
In some respects, this stumble reflects gaming’s new popularity. When it was less of a mainstream activity it was not so connected to the wider economic cycle. The success of the family-friendly Wii has broadened gaming’s appeal, but the new players it has attracted are less fanatical garners who are more likely to cut back in hard times. During 2009 more people turned to mobile, web-based or second-hand games, says Mr Harding-Rofls.
Another way of looking at things, however, is to say that spending on gaming is driven by big hits, and that the slight decline in 2009 reflects creative rather than economic weakness. Entertainment industries always have their ups and downs, says Shigeru Miyamoto, the creative force behind many of Nintendo’s biggest games. There was an unusually large number of hits in 2008, which boosted sales, and fewer big releases in 2009 until late in the year, which may explain the weak mid-year sales. The biggest hit was "Modern Warfare 2", released in November, which became the fastest-selling game in history, selling 7 million copies worldwide on its first day. The top 20 games took a larger share of sales in 2009 than in 2008, which shows that the games industry is becoming increasingly polarised between hits and misses. Hence the hit-and-miss results of the big publishers of video games.
Overall, says Mr Miyamoto, 2009’s crop of games may just have been less compelling. "We were not able to produce fun-enough products," he says. That highlights the importance of continued innovation, he says—but it leaves unanswered the question of whether gaming is indeed recession-proof.
From the fourth paragraph, we can know that______.

A:entertainment have been in the slight decline recently B:creative games will bring good sales C:sale increasing by the end of 2009 is due to big hits of games D:"Modern Warfare 2" benefits from the Shigeru Miyamoto’s innovations
