More than 2.25 billion cups of coffee are drunk throughout the world each day, and it's likely that many taste bitter. Now, a new study suggests that coffee fans can make their drink sweeter by changing the color of their cups. Researchers from Oxford set out to prove whether the claim that coffee drunk from a white cup tastes biter was true. They used 36 volunteers and three different colored cups---blue, white and transparent glass--- to examine the claim. In one experiment, the white cup increased the intensity of the coffee taste relative to the transparent cup. Then, in a second experiment, coffee drunk from the white cup was found to taste less sweet when compared to the other colored cups, while the blue cup made the coffee taste the sweetest. The scientists believe that the color brown may be associated with bitterness, and coffee in a white cup appears the brownest. "Our study clearly shows that the color of a cup does influence our sense of the coffee taste," leading author Dr George Doorn, wrote in an article for The Conversation. "The effect of the color of the cup on the taste of the coffee reported here suggests that cafe owners should carefully consider the color of their cups," he said. "The potential effects may spell the difference between a one-time purchase and a return customer." Actually, the idea that color can change the food and drink taste came out many years ago. A study published last year reported that red, strawberry-flavored cake served on a white plate was rated as 10 percent sweeter than the same food presented on a black plate. The passage is mainly about _ . A) the popularity of sweet coffee. B) an experiment made in Oxford. C) the effect of cup color on coffee's taste D) useful tips on how to make coffee.

(Question)
TUVALU, a tiny country in the Pacific Ocean, has asked for help as it will be swallowed up by the sea. Storms and huge waves are a constant threat and none of Tuvalu's nine little islands is more than five meters above sea level.Salt water is already entering the country's drinking water supply, as well as damaging plants that produce fruit and vegetables.Without urgent help, the country's days are numbered. But Tuvalu is not the first place to face sinking into the sea.Venice, a historic city in Italy best known for its canals, has sunk about 24cm over the past 100 years.Experts say that it will have sunk another 20-50cm by 2050.A century ago, St.Mark's Square, the lowest point city, flooded about nine times a year.Nowadays, it happens more than 100 times.While Venice is slowly sinking into the mud on which it stands, global warming causes Tuvalu's rising sea level. The average global temperature has increased by almost 0.5 centigrade degrees over the past century; scientists expect it rise by extra 1-3 degrees over the next 100 years. Warmer weather makes glaciers melt, and adds more water to the ocean.The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise.The sea level has risen about 10-25 cm in the last 100 years. The main cause of global warming is human pollution.Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2.This adds to the power of the greenhouse effect, making the planet even warmer. Many scientists believe that, if the warming is not stopped, there will be huge climate changes.The sea level could rise by one meter this century. Should this come true, the sea would swallow up millions of homes and the world will be flooded with "climate refugees" looking for somewhere to live. Which of the following is False according to the passage? A) The sea level has risen about 10-25 cm in the last 100 years for warmer temperatures. B) The average global temperature has risen by 1-3 centigrade degrees over the past 100 years. C) The warmer temperature causes the sea level to rise. D) There will be huge climate changes unless the warming is stopped.
