Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Now scientists have discovered that the dogs behave like their masters, too. Just like children, they use a " look and learn" ways when they go about their tasks. Scientists at Oxford universities designed an experiment to test if the dogs have the ability to copy humans' actions by using a simple wooden box. 10 owners showed their dogs how to open the wooden box .Sometimes they use their heads to push it and sometimes they use their hands. 10 dogs were divided into two groups---Group1 and Group2. In the first part of the test, Group1 were rewarded with a piece of meat for copying their owner's actions. Group2 were rewarded with food for not copying and using other ways. With each dog the experiment was repeated hundreds of times. Scientists recorded the time to see which group was first to get 85% right. They found that Group1finished the task much sooner than Group2. In the second part of the test, all the dogs were only rewarded for copying the way that their owners used. Group1 reached the 85% mark more quickly than Group2. So the scientists draw a conclusion: "Like humans, dogs can copy actions that they see. Dogs' imitative behavior is shaped more by their interactions with humans than by evolution ." Scientists said,"A dog's behavior is influenced much like that of a child; they look and learn similar behavior. We hope that owners understand the importance of their actions and use this knowledge to set good examples and therefore have a good effect on the behavior of their pets." Question: The scientists believe dog's imitative behavior mainly comes from _ . Options: A: proper rewards B: domestication C: human-dog interactions D: evolution
Ans: C
I'm taking a test and have to guess the right answer to the question after the article. Article: What's the red star in the sky through a telescope ? It is Mars. Do you want to know more about it? Take the "Mars Orbit Express"! "Mars Orbit Express" is a space probe . It was sent towards Mars by American scientists on August 12th,2005. Its tasks are to study Mars' atmosphere and return photos to Earth. But before that "Mars Orbit Express" must travel about 100 hundred million kilometers and seven months. It reached Mars' orbit in March,2006. Mars and Earth have similar weight and size. However,Mars is closer to the sun than Earth. Mars is very cold. The average temperature is below 50degC. The temperature at noon only reaches 20degC during a Mars day. Its atmosphere is mostly CO2. It has much sand and two moons---Phobos and Deimos. Scientists think Earth and Mars had similar beginnings 4.6 billion years ago. But while Earth supports millions of lives,Mars becomes bad. "Earth easily could have turned out like that." said an scientist, "It is important for us to find out why and Mars Orbit Express' should do that." "Mars Orbit Express" also would help scientists to learn what might happen to Earth in the future. "Mars Orbit Express" would work for about four years. Question: One of the tasks of Mars Orbit Express is _ . Options: A: taking pictures of Mars B: studying the weight of Mars C: finding out distance between Earth and Mars D: telling the time it takes to go from Earth to Mars
