[EX Q]: Article: Dreams can be familiar and strange, fantastical or boring, but some dreams might be connected to the mental processes that help us learn. In a recent study, scientists found a connection between nap-time dreams and better memory in people who were learning a new skill. In the study,99 college students between the ages of 18 and 30 each spent an hour on a compute, trying to get through a virtual maze .The maze was different place each time they tired--making it even more difficult. They were also told to find a particular picture of a tree and remember where it was. For the first 90 minutes of a five-hour break, half of the participants stayed awake and an half were told to take a short nap .Participants who stayed awake were asked to describe their thoughts. Participants who took a nap were asked about their dreams before sleep and after sleep--and they were awakened within a minute of sleep to describe their dreams. Stickgold, a neuroscientist ,wanted to know what people were dreaming about when their eyes weren't moving during sleep. Four of the 50 people who slept said their dreams were connected to the maze. Some dreamed about the music that had been playing when they were working ; others said they dreamed about seeing people in the maze. When these four people tried the computer maze again, they were able to find the tree faster than before their naps. Stickgold suggests the dream itself doesn't help a person learn--it's the other way around.He suspects that the dream was caused by the brain processes associated with learning. All four of the people who dreamed about the task had done poorly the first time, which makes Stickgold wonder if the dreams show up when a person finds a new task particularly difficult. People who had other dreams, or people who didn't take a nap, didn't show the same improvement.
Question: Before having a short nap, participants of the experiment were asked to _ .
Options: (A) stay in a different place in the maze (B) design a virtual maze which is difficult to get through (C) experience the experiment and try to remember something (D) get through a virtual maze on a computer from the same place
Asnwer: C
[EX A]: Yes

[EX Q]: Article: Have you seen a yellow-and-black salamander ? How about a scarlet frog? Scientists haven't spotted either species in more than 20 years. What happened to them? Are the creatures still out there, or are they extinct? Those are questions that scientists hope to answer. They recently set out around the world in search of those and other long-missing amphibians. An amphibian is an animal that spends part of its life in water and part on land. Frog, toads , and salamanders are amphibians. The experts are looking for about 100 species. They are searching at least 14 countries on five continents. They will look for the salamander in North America. They hope to find the scarlet frog in South America. They're also looking for species in Africa, Asia and Australia. Scientists are hopeful that they'll find the amphibians--and soon! If the creatures are out there, they may need help. Many amphibians are endangered. The animals face many dangers including pollution and diseases. People cut down the forests where they live. "If researchers can find the missing creatures, they might be able to figure out how to save them," explains expert Robin Moore. He began searching for the amphibians earlier this month. "This search will tell us a lot about how amphibians are doing," Moore told WR News. "I don't know what we will find, but that makes the search even more exciting." Lost in the Wild Scientists' hunt for missing amphibians is under way. Read about some of the species they hope to find. Turkestanian salamander This salamander is a mystery to scientists. Experts found a few of them more than 100 years ago, but none have been seen ever since. Gastric brooding frog Experts first discovered this frog in 1914 in eastern Australia. It may be extinct because of disease and habitat loss. Rio Pescado stubfoot toad Last sighting: 1995, in South America Scientists hope to find this spotted toad in rivers and rainforests in Ecuador. The animal faces threats including pollution and disease.
Question: Which of the following animals hasn't been seen for over a century?
Options: (A) Rio Pescado stubfoot toad. (B) Gastric brooding frog. (C) Turkestanian salamander. (D) Scarlet frog.
Asnwer: B
[EX A]: No

[EX Q]: Article: The International Space Station,one of the most ambitious space projects ever and a key launching board for exploration of the solar system,turns l0 years old Thursday. On Nov.20,1998,the first part of the space station was launched by the Russians from Kazakhstan.NASA followed up two weeks later with Piece No 2 carried up by a space shuttle. The space station has grown into a giant outpost 355 km up,home to three people at any given time--soon to be six. Thanks to the newly arrived shuttle Endeavour,the space station now has five sleep stations,two baths,two kitchens and two mini--gyms.Ahogether,there are nine rooms,three of which are full scale labs. The United States has financed the main part of the project,estimated to cost some 100 billion dollars.Fifteen other countries have also contributed,including Russia,Japan,Canada,Brazil anti eleven nations belonging to the European Space Agency. Fhe space station has traveled 2.1 billion km,orbited Earth more than 57,300 times,hosted 167 people from 15 countries,and served up more than l 9,000 meals "The ISS is the largest ever expenment in international technological cooperation," said John Logsdon. a historian at the National Air and Space Museum in US. "1 think it's a necessary stepping stone to long--term human activities in new Areas of operations,"Logsdon said.The station is"off the planet and it's the first Step outward--not all end in itself,but a step along the way."
Question: Piece No 2 of the ISS was put into orbit oil _
