[EX Q]: Article: If you're not a fan of KFC's famous Double Down hot dog, don't worry! KFC in the UK is developing a new treat: an edible coffee cup. The product is still in the trial stage and not yet available for purchase, but according to a KFC news report, the treat is made from a unique biscuit, wrapped in sugar paper, and lined with a layer of heat-resistant white chocolate, which helps keep the coffee hot. As you drink the coffee in the cup, the white chocolate lining will begin to melt slowly, and the biscuit begins to soften. But it doesn't end there --- the cups are not only edible, they also have a pleasant smell. KFC partnered with The Robin Collective, an experimental food company, to make the cups with coconut sun cream, freshly cut grass and wild flowers scents. According to the news report, that's because the scents arouse the positive memories we associate with warm weather, sunshine and summer holidays. Sounds ... delicious? A manager at KFC said, "We have been experimenting with the edible packaging in limited quantities to see if it could be a popular product in the market. We believe if our customers occasionally like to have their cake and eat it, why wouldn't they want to have their cup and eat it instead! " The edible cups will only be available in the UK when it comes out. According to a spokesperson for KFC, there are at present no plans to bring it to the U.S. yet.
Answer: prevent the heat giving off soon
[EX A]: The cup is lined with a layer of white chocolate to _ .

[EX Q]: Article: Let's pretend we're sailing down the Rhine River on a pleasure boat. The Rhine is one of the main waterways of Germany, and the river traffic is heavy. It's interesting to watch the many boats going up and down the river. But the river traffic is not nearly so interesting as the beautiful scenery along the banks and hillsides. The boat is passing many old castles. We can see people working in the vineyards on the hillsides. There are vineyards as far as the eye can see. Wine from the Rhine Valley is famous all over the world. Suddenly our boat slows down and begins to turn a little. We are coming to a sharp bend in the river. On our right we can see a rocky cliff over 400 feet high. At first it looks quite ordinary, but there is nothing ordinary about it. There are many stories, poems, and songs about the cliff. We are looking at the Lorelei. Then someone on the boat begins to sing in German, the song of the Lorelei. It is a song about a beautiful siren who has lured many sailors to their deaths. The siren is supposed to sit on the rock combing her long golden hair and singing. The sailors who hear her forget to steer , and the current of river hurls their boats on the rocks and dashes them to pieces. Soon other people on the boat begin to sing. The beautiful song adds to special magic to the moment, and you begin to realize why so many people have made this trip down the Rhine to see the rock of the Lorelei.
Answer: to see the beautiful scene along the banks and hillsides
[EX A]: The most interesting thing to those who are sailing down the Rhine River on a pleasure boat is _ .

[EX Q]: Article: Robots are common in today's world. They manufacture cars, work in space, explore oceans, clean up oil spills and investigate dangerous environments. And now, scientists at the University of Manchester are using a robot as a laboratory partner. The researchers at the university created the robot in 2009 and named it Adam. Despite the name, Adam is not a humanoid robot. It is about the size of a car. Adam was built to do science and make discoveries. Ross King is the leader of the University of Manchester research team. He says the robot made a discovery about yeast , a kind of fungus used in science as a model for human cells. "Adam hypothesized certain functions of genes within yeast and experimentally tested these hypothesizes and confirmed them. So it both hypothesized and confirmed new scientific knowledge." Adam's success as a scientist led to the creation of another robot scientist named Eve. Researchers developed Eve to design and test drugs for tropical and neglected diseases. These diseases kill and infect millions of people each year. Drug development is slow and costly. Experts say it can take more than 10 years and about $1 billion to discover and develop new medicines. Drug manufacturers are unlikely to get their investment money back. So the University of Manchester developed a low-cost test that shows whether or not a chemical is likely to be made into an effective medicine. Mr. King says that other drug testing methods were not very effective. "How it works conventionally is you use robotics as well and you have a large collection of possible drugs. You test every single compound. And you start at the beginning of your library and continue until the end, and stop. So it's not a very intelligent process. The robotics doesn't learn anything as it goes along, even if it's tested a million compounds, it still doesn't have any expectation of what will happen next when it tests a new compound." Mr. King says that Eve is different because the robot learns as it tests different compounds. He says the robot is designed to ignore compounds that it thinks unlikely to be good. It will only test the compounds which have a good chance of working. Eve has discovered that a compound known to be effective against cancer might also be used to fight against malaria and other tropical diseases. Mr. King says he hopes to completely automate the drug testing process with robots like Eve to create and test new chemicals. But he says humans remain in control of the manufacturing process.
Answer: work in the laboratory
