I'm taking a test and have to guess the right answer to the question after the article. Article: Research on the human brain has been attracting the attention of more and more scientists in recent years. One of the latest research topics is how to change the human brain or combine the computer and the human brain, i.e., to transplant a chip into human brain. This innovation may make everyone's dream come true. If we compare a human brain to a hard disc, what the scientists do is to enlarge the capacity of the hard disc. There are some difficulties in such transplant experiments, but scientists never give up. Experiments were started on animals. In 1996, a transplant experiment performed at the Defense and Military Physiology Research Institute in the U.S. turned a bear into a dolphin. The dolphin was named Ted, and the bear was named Tallin. Using the most advanced technology, deep and detailed studies were made of the swimming action memory area in Ted's brain by the scientists. They got a lot of useful information. The information was saved into a button-sized chip, which was then transplanted into the action memory area in Tallin's brain. The information saved on the chip was released by means of electric power. Recently, another memory transplant was performed at the Motor Nerve Research Institute of the University of California. The transplant was performed from a dog named "Genius" to a dog named "Idiot". "Genius" could understand and follow up to 100 gestures and orders made by its master. It was a real genius. "Idiot" was the younger brother of "Genius". It had no contact with people at all since its birth. It became an animal with nothing in its brain, without any memory. _ When the two dogs woke up, "Idiot" had all the abilities "Genius" possessed. It could follow every gesture and order given by its master. But "Genius" gave no response to its master, and in fact did not recognize him at all. Question: It could be inferred from the passage that in the future _ . Options: A: human beings will be healthier B: animals will be more tender C: human beings may get knowledge more quickly D: animals will cause more damage to the environment

I'm taking a test and have to guess the right answer to the question after the article. Article: When Cath Pirret and her husband Iain took their daughters Jessie, 10, and Holly, 7, to Britain earlier this year, it was a trip that was all about showing the girls where their parents grew up. But there were also some key sightseeing opportunities, such as Stonehenge, Hadrian's Wall and Tate Modern, before heading to Paris to see the Mona Lisa and Venus de Milo. So, what did the couple from Melbourne hope their girls would get from the trip? "A greater understanding that travel is not a difficult thing to do," Cath says."Some of the highlights are to meet new people and adapt to lots of different situations." Cath believes that children, in order to truly benefit from travel, need to be old enough to understand and appreciate the experience. Sydney-based ABC Radio broadcaster and film critic C.J. Johnson travelled a lot with his parents as a child. His father was "really into rivers" and decided he was going to make it the "family mission" to see the "seven great rivers of the world". There's no doubt, thanks to a richer society and the greater ease and access to all forms of travel, that few -- if any -- generations of parents and children have ever had the ability to journey together as far, as wide and as deep as the present one.Travel brings history to life, builds children's independence and opens their minds. A child's view also helps adults to see the world through new eyes. For Keith Bellows, the award-winning editor-in-chief of the American National Geographic Traveler magazine says the world is simply"the greatest classroom we have". He's convinced, like Spicer, that any parent willing and financially able to give the gift of travel offers a gift that keeps on giving. "Children who learn to travel will travel to learn," he says. "And they will do it all their lives." With that in mind, Bellows, a father of three, wrote a book, 100 Places that Can Change Your Child's Life. Question: When Johnson was a child, _ . Options: A: he made a decision to see the greatest rivers B: he fully understood his family mission C: he was forced to keep his father company D: he learned a lot and developed a broad outlook

I'm taking a test and have to guess the right answer to the question after the article. Article: Smart home applications can share all kinds of helpful information with homeowners. There appears a new housing platform which can detect the stress on electricity -- and the stress on the heart. "There is a growing population of elderly people, and there are statistics to show that more and more of them are going to live alone in the home," said Johann Siau, a senior lecturer at the University of Hertfordshire in the U.K., who was leading the InterHome project. The system was originally designed to provide remote access to a house so owners could be more energy-efficient. In a small type of the system, set-in controller devices connect securely to the Internet. The owner can then monitor them with a cell phone or computer. User feedback helps the system adapt to routines, saving on electricity. While thinking about responding to user behavior and an increasingly elderly population, the researchers decided to add wristband technology that senses important organs of the body such as body temperature and pulse, Siau said. "If someone were to fall, it would detect the fall and it would immediately start the monitor of the pulse to see if the person has gone into shock ," he said. The wristband communicates with the home system wirelessly. Data from the band can be securely transmitted to the home network and accessed by authorized users. "We're working on trying to reduce it to a level where it could potentially be a wrist-sized product," Siau said. But he warned that the technology presented new challenges. "When you start using that on a larger scale, you have issues of privacy or security," he said. Siau said the InterHome home system isn't intended to invade privacy. "We're thinking about the elderly people who are living alone with no one looking after them," he said. "Hopefully this will be able to decrease some concerns and possibly save a few lives." Question: The system was first designed for a house owner to _ . Options: A: keep watch on his house B: keep his house safe C: monitor the elderly people inside D: save electricity
