Article: Can people change their skin color1 without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin color1. The gene comes in two versions, one of which is found in 99 percent of Europeans. The other is found in 93 to 100 percent of Africans, researchers at Pennsylvania State University report in the latest issue of science. Scientists have changed the color1 of a dark-striped zebrafish to uniform gold by inserting a version of the pigment gene into a young fish. As with humans, zebrafish skin color1 is determined by pigment cells, which contain melanin . The number, size and darkness of melanin per pigment cell determine skin color1. It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation in the gene for melanin production. This results in less pigmented skin. However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebrafish genes. Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun , which can cause skin cancer. But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng. "Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color1," said Cheng. The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin color1 without damaging it like chemical treatment did on Michael Jackson. ks5u Question: The writer's attitude towards the discovery is _ . Yes or no, is the answer "positive"?
No

Article: Although new laws have been passed in some American states to cut down on distracted driving, many accidents and deaths were still related with it, especially using cell phones while driving. Recently the Obama administration is considering disabling cell phones in cars, aiming to out down cell-phone-related road deaths. Transportation Secretaryy Ray LaHood, the nation's anti-distracted-driving supporter, said in an interview on November 18 that federal officials are looking at technology to disable cell phones inside cars. "I think it will be done," LaHood said."I think the technology is there and 1 think you're going to see the technology become adaptable in automobiles to disable these cell phones.We need to do a lot more if we were going to save lives." Also on Thursday, the transportation government started a new "Faces of Distracted Driving" video campaign that features people who have been killed or lost their loved ones because of inattentive drivers.The video features heartbreaking stories of children killed in crashes because of phoning or text messaging, and new videos are expected to be added every few weeks. A driver is four times more likely to crash while using a mobile phone.More than 5,500 people were killed last year by distracted drivers, and another 500,000 were injured.LaHood has said it is never safe to talk on a cell phone while driving, hands-free or not, because it can really cause distraction. Incidentally, a lot of people seem to agree with this viewpoint--a new research shows nearly two-thirds of Americans support a national ban on the use of cell phones while driving, even if the driver is using a hands-free device .But the research didn't ask how people feel about government-issued mobile phone scramblers or other disabling devices. Question: We can infer from the text that _ . Yes or no, is the answer "the writer is not sure whether disabling devices will be accepted by the drivers"?
No

Q: Article: Twelve years ago, Rachel Miller was lost when it came to her son John. The 7-year-old was seriously disabled because of his autism . Unable to speak, he withdrew from people at school and, worse, from his family. In March 2003, Miller was introduced to Jeff Hancock, a one-on-one therapist for people with autism. Hancock was hired to be John's companion. The two would go people-watching at the mall on the weekend. Hancock chatted throughout their trips, even though John couldn't talk back. Their relationship developed when Hancock introduced John to the Special Olympics. Whenever John was running or being active, he was smiling. When John turned 12, Hancock introduced him to track at the Special Olympics. For the first three years, the pair just observed the sport by watching practices and events. Hancock worked daily with John, showing him everything, including where to sit, stand and walk, so he would understand the flow of the events. Eventually, the lessons clicked, and John was off doing 50-meter sprints. But as John got older, he got stronger and faster. At 16, he was jumping hurdles and doing 800-meter races. Miller started seeing her son as a serious athlete. In May 2014, John's training brought him to the Special Olympics State Summer Games in Orlando. The 18-year-old was competing in the 800 meters and the 110-meter hurdles. As the 800 was setting up, Miller remembered, she pressed her face against the fence, anxiously waiting for John to compete. But as soon as the race started, all Miller saw was an athlete, her athlete. "I just wanted to see the best performance. It seemed much more significant than whether he would ever speak or respond to me," she said. John ended up winning the gold medal for the 800. Sports completely changed John, and Miller said that is because of Hancock."A person with a disability can feel hopeless and isolated, and I think that can happen to parents, too. " Question: The passage is mainly carried out. Yes or no, is the answer "in time order"?
A: No

Article: My parents were in a huge argument, and I was really upset about it. I didn't know who I should talk with about how I was feeling. So I asked Mom to allow me to stay the night at my best friend's house. Though I knew I wouldn't tell her about my parents' situation, I was looking forward to getting out of the house. I was in the middle of packing up my things when suddenly the power went out in the neighborhood. Mom came to tell me that I should stay with my grandpa until the power came back on. I was really disappointed because I felt that we did not have much to talk about. But I knew he would be frightened alone in the dark. I went to his room and told him that I'd stay with him until the power was restored. He was quite happy and said, "Great opportunity " " What is ?" I asked. " To talk, you and I," he said. "To hold a private little meeting about what we're going to do with your mom and dad, and what we're going to do with ourselves now that we're in the situation we are in." "But we can't do anything about it, Grandpa," I said, surprised that here was someone with whom I could share my feelings and someone who was in the same "boat" as I was. And that's how the most unbelievable friendship between my grandfather and me started. Sitting there in the dark, we talked about our feelings and fears of life--from how fast things change, to how they sometimes don't change fast enough. That night, because the power went out, I found a new friend, with whom I could safely talk about all my fears and pains, whatever they may be. Suddenly, the lights all came back on. "Well," he said, " I guess that means you'll want to go now. I really like our talk. I hope the power will go out every few nights!" Question: Grandpa was happy to see me because _ Yes or no, is the answer "he could discuss the problem with me"?
(Answer)
No
