Question: Article: Coral reefs are not just beautiful to look at,but also very useful.They shelter nearly 25% of ocean life and provide food for billions of people.However, like many other species,this amazing ecosystem is in danger of dying out! There are two main reasons for the destruction--the rising carbon dioxide levels caused by global warming as well as human influences like bottom operation.While not much can be done about the former,the loss caused by the latter can be reduced. Bottom operation involves dropping nets to the ocean bed and then dragging them up when filled with fish.This action damaged the ocean floor,causing the coral branches to separate from the reefs.While that is very discouraging,the good news is that if these branches are found quickly,they can be saved.At present,that work is being performed by volunteer divers. But the method has only limited success because they cannot stay long underwater, nor reach depths of over 200 meters where some of the deep-sea coral grows. However,this is not the case for Coralbots--the robots that can constantly seek out broken branches.A team of 'coral bots',each individually working to simple rules will piece together damaged bits of coral, allowing them to regrow. They are programmed to be able to distinguish between other things and the coral.The robots work together in groups,similar to bees.If one coralbot is damaged, then the others will still be able to complete the task. Dr Lea-Anne Henry said:"The project of using coralbots offers us the possibility to restore the function of reefs.It is in the final stage of testing.Once ready, the researchers hope to build hundreds of _ and use them effectively in the waters off Scotland and then hopefully in the oceans across the world."
Question: Which of the following is a cause of the danger that coral reefs are facing?
Options: (A) The appearance of new creatures. (B) The seriously polluted sea water. (C) The activities of volunteer divers. (D) Human activities like bottom operation.
Asnwer: D

Answer: Yes

Question: Article: A lot of people these days believe Valentine's Day is a made-up holiday designed to promote the sale of greeting cards and gifts. And while there may be some Arguments for that, there is a mysterious story as to why February 14th has become known today as "Valentine's Day." Our story dates back centuries ago, to the Roman Empire, and the martyrdom of two or three Christians named Valentine. At least one of those Valentines is thought to have been killed on February 14th. Legend has it that this particular Valentine wais killed by a Roman emperor because he secretly presided over the marriages of young men and women, against the wishes of the Emperor, who wanted only single men to fight in his army. However, there is no historical evidence to back this up. But what is widely known is that the love-element to Valentine's Day can be first traced to the poetry of Geoffrey Chaucer. Chaucer wrote a poem in 1382 to mark the anniversary of his King's engagement, and scribed a line -- "For this was Saint Valentine's Day, when every bird cometh there to choose his male." From this point, on Valentine's Day became intertwined with love. But for the pessimists out there who see Valentine's Day as a commercial idea, there is some historical evidence to back this up as well! The true popularization of Valentine's Day can be traced to late 18th century England, when a British publishing company first started selling paper Valentine's Day cards with tender words on them. They became so popular that by the middle of the 19th century, some 1.3 billion British pounds a year were being spent on Valentine's Day gifts.
Question: What is this text mainly about?
Options: (A) What Valentine's Day means. (B) How Valentine's Day came about/ (C) Why Valentine's Day is so popular. (D) When people created Valentine's Day.
Asnwer: A

Answer: No

Question: Article: Einstein was the greatest scientist of his age. But he was almost as strange as his Theory of Relativity. Once, while riding a street car in Berlin, he told the conductor that he had been given too much change. The conductor counted the change again and found it to be correct, so he handed it back to Einstein, saying "The trouble with you is you don't know your figures." He had nothing and thought little of the things most people set their hearts on-- fame and money. He didn't want money or praise. He made his own happiness out of such simple things as his work and playing the violin and sailing his boat. Einstein's violin brought him more joy than anything else in life. He led a very simple sort of life, went around in old clothes that needed pressing, seldom wore a hat, He shaved with the same soap that he used for his bath. The man who was trying to solve the most difficult problems of the universe said that using two kinds of soap made his life completely too complicated .
