[Q]: Article: For Kim LeBlanc, knowing that her son Tyler's organs, eyes and other tissues have given life or healing to others is helping her cope with the loss of her child, who was struck by a truck in Guelph on May 31. Tyler was believed to have been texting a friend when he stepped onto a high-traffic road against the green light and was struck by the truck. Then he was sent to a Hamilton hospital. Surgery was performed to ease the pressure in his brain, but .the family was told he would not recover. "With all of his injuries, I just prayed all night for a miracle. And I was granted a miracle, but not in the way I'd expected," says LeBlanc, her voice choked by emotion. The family decided to donate Tyler's organs, a choice she believes her kind and considerate son would have made on his own. It's also a choice that transplant programs wish would be made more often, because the need for donor organs is far more than the supply worldwide. More than 1,500 people in Ontario are on the waiting list for life-saving organs, and one dies every day because an organ has not become available in time. Across Canada, the gap between donations and the need for organs continues to widen. At the end of 2010, more than 4,400 Canadians were on the waiting list for donor organs, including 3,362 needing a kidney. That year, 229 died before the organs they needed became available. LeBlanc recalls the morning when her son was taken off life support and his organs were removed. Despite living what she calls a parent's absolute worst nightmare, LeBlanc says she has got the strength to bear such an unbearable loss. "He's still there. He's still living. And he's still breathing. And he's brought so much joy to families," she says. "He's my hero. He really is my hero."

[A]: Tyler was struck by the truck mainly because _ .

[Q]: Article: Man has a big brain. He can think, learn and speak. Scientists thought that men are different from animals because they can think and learn. They know now that dogs, cats and birds can learn too. They are beginning to understand that. They make noises when they are afraid, or angry or unhappy. Apes can understand some things more quickly than human, one or two of them have learnt a few words. But they can not join words to make sentences. They can not think like us because they have no language. Language is a wonderful thing. Man has been able to build a modern world because he has language. Every child can speak his own language very well when he is four or five, --but no animal learns to speak. How do children learn it ? Scientists do not really know. What happens inside our body when we speak? They do not know. They only know that man can speak because he has a brain.
Answer: Man's Brain

[Q]: Article: Elephants and people are in competition for space. In much of Africa, elephants are now put in national parks. Elephants suffered a serious and steady decrease in numbers in the 1970s. This was the same time when scientists were beginning to learn a great deal about elephants and their behavior. Studies through the 1980s and into the 1990s showed a lot about their sounds and methods of communication. In Kenya alone, in the 1970s and 1980s, the elephant population decreased from 170,000 to 25,000. The sharp drop in numbers was the result of poachers illegally killing elephants for their ivory. The price of ivory went from $3 a pound to $50 to $100 a pound. Africa became very attractive to poachers. Bull elephants carried the largest tusks , so they were more often killed. With males gone and older females killed by poachers as well, there were many young elephants unable to benefit from the wisdom of the older females and matriarchs, who lead the herds. Kenya took a stand, international trade in ivory was officially forbidden, and $3,000,000 worth of confiscated ivory was burned in Kenya. The following year, only 50 elephants were lost to poachers in Kenya instead of 3,000. But Kenya has the fastest growing human population in the world. People throughout Africa won't tolerate elephants eating their crops and destroying their livelihoods. In South Africa, elephants live behind the fences of national parks. In some parts of Africa, big-game hunters pay a lot of money to hunt elephants. This keeps their numbers down, and the money goes toward conservation. In Kenya, there were some attempts at birth control to keep the elephant population at manageable numbers to reduce conflicts with people. Faced with a growing human population, elephants are losing the battle for space. It's unlikely, though, that they will become extinct. They will live in natural parks that bring tourists to Africa as well as India and other parts of Asia. The money from tourism will help elephants to survive.
