Article: For many years people in Estonia have been leaving their rubbish in the forests. Rainer Nolvak, a businessman and his friends wanted to clean up all the rubbish in Estonia. The rubbish was not just an environmental problem. It was a problem of people's attitudes. Rainer Nolvak got together with a team of 20 friends and they began to make a plan about how to clean up the rubbish. Soon, over 600 people joined in the group. They named the project Let's Do It! Estonia. The Ministry of the environment gave them some support. Many other companies joined in the group. Famous actors and singers also took part. Even the President of Estonia joined in. They sent information about Let's Do It! Estonia throughout the country. Technology experts developed a special computer program. Team members went into the forests to find where the rubbish was. They used their mobile phones to mark every place where they found rubbish and send the information to the computer program. Then, the marked rubbish places appeared on the map. Anyone could go on the Internet and see the map. The team found a surprising result. There were over 10,000 tons of waste in the forests of Estonia. When people saw how much waste was around their own homes, they were shocked. Thousands of people began to help. The team chose May 3, 2008 as the day to clean up the rubbish. On May 3, more than 50,000 people helped to get rid of the rubbish. They moved over 10,000 tons of rubbish in only one day! This was amazing for the environment in Estonia. But it was also an important step for Estonian society. Rainer Nolvak gave a speech at a conference in the Balkans. He said: "The most important thing we did was build a team. It changed every one of us. We had to connect to people. We had to see that the rubbish was our problem. At times we are afraid of sharing. When we are together and there are many of us, we are not afraid.' Question: What do we know about the project Let's Do It! Estonia? Yes or no, is the answer "It got great support from all over the country."?
**Answer**
Yes

Article: When a caterpillar feeds on a tomato leaf , the plant moves rapidly to meet with a defensive response , systematically releasing " proteinase inhibitors " -- proteins that interfere with the caterpillar's digestion -- throughout the plant , especially in the leaves . But how does the message get from the wounded leaf to the rest of the plant ? Most scientists believed the alarm was spread by chemical messengers until a team of researchers headed by David Weldon-- a biologist at the University of East Anglia in Norwich , England -- made a shocking discovery . An injured leaf , the researchers found , sends an electrical signal to warn neighboring leaves of upcoming danger . It's a " terribly tiny current " driven by an electrical potential difference of only 20 millvolts , says Weldon , who measured the voltage after electrodes were attached to the plant's surface . " Right now , all we can say is that there is a correlation , " Weldon notes . " If you wound the plant , you'll see an electrical signal accompanied by a biochemical response . " To learn more about the reaction , Weldon's team plans to insert electrodes within the pant tissue ( rather than on the surface ) to determine what's going on at the cellular level . The findings may help explain other mysteries surrounding plants . For example , many plants start to flower in springtime , as days grow longer , but plants sense the change in the day length through their leaves , while flowers begin to bloom at the buds . " There must be a signal from the leaf to the growing points , " Weldon says . " So far , no one has come up with a convincing chemical mechanism . Maybe an electrical signal is involved . " Question: What question do scientists hope to answer with further research ? _ Yes or no, is the answer "Do plants send electrical signals that tell them it is time to grow ?"?
**Answer**
No

Article: A neighbor of mine, while visiting his mother in Boston, took her to a shoe store to buy a new pair of shoes. While she was trying on different styles, my neighbor took the manager aside. "When she picks out a pair that she likes," he said, "Just tell her that the price is 12 dollars. I'll pay the regular price. I don't care how much it is." The following week, my neighbor was walking by the shoe store and the manager recognized him and called him in. "What's the problem?" asked my neighbor as he entered the store. "Wasn't my check any good?" "That's not it," answered the manager, "The problem is that your mother is bringing all her friends in for those 12-dollar shoes!" Question: The manager called my neighbor in when he saw him because _ . Yes or no, is the answer "he found it hard to satisfy his customers"?
**Answer**
No

Article: The ancient Olympic Games were held in a sacred valley at Olympia at western Greece. The earliest records of the Games go back to 776 B.C.. These contests were held every four years. They were important to the Greeks. When they took place, all wars were stopped. No one dared to break the truce of Olympic. Criers announced the names of winning athletes everywhere in the land. Artists made statues of them. Poets wrote about the Olympic heroes. The first Olympians raced the length of the stadium at Olympia--about 200 yards. But later other events were added:longer races, broad jumping, the javelin throw, the marathon race, and the discus throw. Then boxing, wrestling and horseback riding were also added. In the beginning, only Greeks competed in the Games. But in later centuries, athletes from other lands joined. In 146 B.C. the Romans conquered Greece. Soon the Games began to change. Under the Romans, they became rougher, wilder, and bloodier. Many professionals took part, which was against the spirit of the Olympics. Finally, Emperor Theodosius of Rome decided that the Olympics were a public danger. He died away with them after the Games of A.D. 392. They had lasted over 1,000 years. Fifteen hundred years passed. Then, in the 1890's, Baron Pierre de Coubertin of France began to interest nations in bringing the Games back. The first modern Olympic Games were held in Athens, Greece, in 1896. They have been held every four years since then, except during the two world wars. Question: The passage is mainly about _ . Yes or no, is the answer "a history of the Olympics"?

No
