But now she has made a name for herself: the world No. 1 player in women's tennis. The 22-year-old Russian. will overtake Serena Williams of the prefix = st1 /USfor top ranking on April 20.  "Before, every place I go, I am Marat's sister. Nothing else," she told New York Times. "I always wanted to be myself, and now finally the results are coming, and people can know me as Dinara Satina." Safina has made it to two great event finals, in the 2008 French and in this year's Australian Open, and won a silver medal in the Beijing Olympic Games. Clearly; family isn't the only connection Safina's and her brother share. Both of their DNA burns with competitive fire. Satin has held the distinction for years of being a hot tempered player on Court. When he lost his temper, he would break a racket . Safina is as emotionally explosive as her brother. A headline in the newspaper The Australian once described her as   "mad as a snake".  The Sydney Morning Herald, during the Australian Open, summed up Safina's volatile emotional state with the headline: "Satina goes from basket case to top of the world." It's not rare for a family to have two top tennis players. Safina's father owns a tennis academy and her mother worked as a coach.   "I had no choice but to become a tennis player, but I don't mind being a tennis player," Safina said. From this talented family she is also given one of her best weapons on court, her size. She is 1.82 meters tall and Weighs 70 kg. But it is hard work that led her to her recent Success. "I hope to prove to everyone over the coming months that I deserve the honor of being world No. 1," she said. Question: What is the passage mainly about? Yes or no, is the answer "How Safina came first in world women's tennis."?
Yes

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: Scientists have done an experiment on a dark-striped zebrafish in order to   _  . Yes or no, is the answer "prove the humans' skin color1 is similar to that of zebrafish in its formation"?
(Answer)
No


Ques: Article: A meteorite   flew fast across the sky and exploded over central Russia on Friday, raining fireballs over a vast area and causing a shock wave that smashed windows, damaged buildings and injured l,200 people. People heading to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt the shock wave. According to Russian space agency Roscosmos, the fireball, travelling at a speed of 30km per second, had burnt very brightly across the horizon, leaving a long white trail that could be seen as far as 200km away. Car alarms went off, thousands of windows shattered and mobile phone networks were disrupted. "I was driving to work, it was quite dark, but it suddenly became as bright as if it were day," said Viktor Prokofiev, 36, a resident of Yekaterinburg in the Urals Mountains. "I felt like I was blinded by headlights." The meteorite, which weighed about 20 tons and may have been made of iron, entered Earth's atmosphere and broke apart 30-50km above ground, according to Russia's Academy of Sciences. The energy released when it entered the Earth's atmosphere was about several thousand tons, the academy said, the power of a small atomic weapon exploding. No deaths were reported, but the Emergencies Ministry said 20,000 rescue and clean-up workers were sent to the region after President Vladimir Putin told Emergencies Minister Vladimir Puchkov to ease the disruption and help the victims. The Interior Ministry said about l,200 people had been injured, at least 200 of them children, and most from broken pieces of glass."While events this big are rare, an impact that could cause damage and death could happen every century or so. Unfortunately there is absolutely nothing we can do to stop impacts." Question: The Russian government's response to the incident was   _  . Yes or no, is the answer "quick and serious"?
Ans: No


Article: By the age of almost four,  Elijah Edney has never had a haircut in his life.  But now he can ' t wait to visit the barber's  -  for two reasons: losing his two - foot - long golden hair will mean   that strangers stop mistaking him for a girl; the hair will be donated to charity to provide a wig     for a child with cancer. Mrs.  Edney, who works in a restaurant, says, "Elijah has always had beautiful hair, so I let him grow it as he w8nted.  It' s like silk.  But now it is at a stage where people mistake him for a  girl and he wants it cut into a boy's haircut. " Mrs.  Edney and her husband want to collect enough money-PS350-to process Elijah's hair  for a sick child.  She says,  "I couldn't bear to see all Elijah's beautiful hair go to waste and my  mum mentioned charities that have human hair made into wigs. " Mrs. Edney says, "If we can raise the amount we want, it will mean a family will not have   to pay for the wig and can receive it for free.  When you've got children yourself, you hope that if  they lost their hair someone would do the same for them by donating their hair. " The two-foot-long hair will be donated to the Little Princess Trust    to  make a wig for children suffering cancer. Elijah keeps telling people he is giving his hair to poor  princesses and he is so excited about it. A spokesman for the Little Princess Trust says, "We're very grateful to anyone who decides   to have their hair cut to donate it to the Little Princess Trust. As a result of hair donations like  this, the charity receives real-hair wigs for free to pass on to families whose children have sadly  lost their own hair through cancer treatment. " Question: Who first thought of charities that use human hair? Yes or no, is the answer "Elijah's grandmother."?

No
