[EX Q]: Article: A Russian legend has a story about the origins of cats. The cat's coat, it was said, was originally designed for the dog, but the dog became so impatient when coats were being handed out that he was told to wait at the back of the queue. The cat was given the fur instead of the dog. This, according to Russian folk storied, is the origin of why dogs dislike cats. A nameless cat with a taste for travel flew for three weeks between New York and Tel Aviv in 1984. It escaped from its owner's cat-box in the plane's luggage compartment on the first trip and all efforts to get it out with bowls of milk and food failed. After nearly 80,000 miles of flying the airline called in a vet who got it out. The Chinese attitude to the cat was not clear. Cats were welcome for their ability to kill mice and were considered suitable pets for women. On the other hand, they were suspected of bring bad luck into the home. In the days before the invention of the watch, it was said that they used their cats as clocks. The pupils of the cat's eyes were believed to gradually change shape with the position of the sun in the sky. At midday they were a narrow line and they gradually became rounder until sunset. Britain's cleanest cat is undoubtedly Harvey, a five-month-old Persian who climbed into his owner's washing machine. He went through a ten-minute wash cycle before someone noticed him through the glass door, and pressed the "stop" button. Harvey was soon back to his usual self. Cats seem to be able to sense earthquakes. Josie, who lives in California, warned her family of a quake in 1971. She wore her owners. Mr. and Mrs. Miller, at 5:50am by jumping onto the bed and running around. When the Miller followed her out of the house, Josie ran off. The earthquake was only a small one, but the cat raised the alarm every time there was a quake after that.

[EX Q]: Article: Surface Exploration. Robots make great explorers on planets,moons,and other landing areas. Aside from earth,just about every surface in the solar system is unsafe for humans to explore. The air on most other planets is insufficient for humans to breathe,making it necessary to wear a space suit and oxygen equipment. The temperatures on these surfaces are much too hot or much too cold for any humans to withstand .Plus there would be complications with radiation,weather,and a lack of gravity. Robots have much less limitation in these areas and can survive much longer under these conditions. Data Collection. Robots are designed for collecting scientific data. Robots are also able to perform many tasks at a time and can process information much quicker and more efficiently. Important scientific projects from detecting minerals,analyzing ground samples,and finding water are all performed much quicker and more accurately by robots. Cost Effective. The use of robots has made the cost of space exploration much less expensive than it would cost for humans to do the work. In order to successfully send humans into space we would need to build a vehicle that can not only carry humans,but also enough food and water to keep them alive for the duration of the trip. Moreover,robots have no problems working for hours on end. Robots never complain,they don't require food or water,and they never need a bathroom break. Space Travel. Over the past 30 years or so there have been many different types of robots used successfully in the exploration of space. Perhaps the most famous and successful robots are the Spirit and Opportunity who have both been exploring the surface of Mars. They have both been very successful with experiments on soil and rocks and have even found evidence of water in Mars' history.
Question: According to the passage,which of the following is NOT true?
Options: (A) The use of robots in space exploration costs more than the use of humans. (B) It may be dangerous for humans to explore the solar system except the earth. (C) Both the Spirit and Opportunity have found the evidence of water in the Mars. (D) Many different types of robots have explored the space successfully.
