Article: Scientific mistakes can live on forever. When 18th-century European museums were first sent specimens of a large furry animal with long curved white claws, they named it"bear-like sloth "because its claws resemble those of South American sloths. Later scientists realized that the species was a tropical bear unrelated to sloths, but its wrongheaded name remains the sloth bear. Rangingprefix = st1 /India,Nepal,Bhutan,Sri Lanka, and possiblyBangladesh, these 150 to 300-pound bears feed on fruits and insects. They sound like bellows when using their flexible noses and lips to blow away dirt and suck up ants. But don't be misled: This gentle-looking bear can be dangerous, occasionally killing villagers who enter the forest. Yognand often talks with villagers to help avoid conflicts."Attacks can be prevented if people avoid certain places." One goal of his research has been to track a dozen radio-collared bears in the dry forests ofIndia'sPannaNational Park. He's discovered that some bears have home ranges of up to 40 square miles. His conclusion:"We need to protect large patches of their _ and maintain links between those patches. Unfortunately sloth bears have to compete with species such as tigers.

Article: Nicaragua's Cerro Negro Volcano has erupted 23 times in the past 100 years,burying homes, crops and people in lava and ashes. But recently the black mountain has become a tourist draw, thanks to a newly invented extreme sport: volcano boarding. Thousands of thrill-seekers have climbed to the top of Cerro Negro, peered into its mouth, then zipped down its rough-and--rocky 41--degree slope on special boards. The volcano-boarding speed, set by an Israeli woman, is 54 mph. "Rushing down an active volcano is something that people expect." Said Anthony Alcalde, an expert volcano boarder. The sport was developed in the mid-2000s by Darryn Webb, an Australian who had climbed the nearby Cerro Negro but was looking for a faster way to get to the bottom. He tried sliding down on surfboards, snowboards, and even a refrgerrator door before inventing a sit-down board made of plywood. "At first, Darryn planned to use a snowboard," said Gemma Cope, a British woman who now runs Big Foot, which offers volcano boarding tours. "But he realized he couldn't cut an edge for there were little rocks everywhere. So he came up with the sitting-down option and realized he can go pretty fast. " Tourists,who are nearly all foreigners,pay $28 for the experience, which begins with a truck ride on dirt roads to Cerro Negr0.a 2,400-foot--high volcano that last erupted in l999.Visitors must carry their boards during the half-hour climb to the top. There,they go straight down the slope and sometimes they have to use their feet for brakes.Along the way.The board fills with rocks and dust,making boarders almost blind.Crashes are common."l wiped out twice and ripped my pants."said Melinda Vorisek, a tourist from Miami."But I'd do it again." Another tourist added:"It was sheer terror. I was eating dirt.But how many people can say they've bombed down a volcano?" Question: From what some tourists said,we can lean that they love volcano boarding because _ Yes or no, is the answer "it is really a challenge to overcome a volcano"?

Ques: Article: Sometimes when we are lost in the day-to-day activities of life and work, we forget there is a part of us that wants to serve and make a difference in the world. It is also a good time to look for ways to express yourself through service to others. Most people want to live a life full of meaning. If you recognize you have a true desire to serve, voluntary work in the community and a spirit of giving can lead you to an understanding of what you care about, what your natural talents are, and what your life purpose is. It can start you on the path to a new life. To live your purpose as fully as possible, use your natural gifts when you serve others. If you are a naturally-born teacher, you could teach students who are struggling with basic reading skills. If you are good at encouraging people, you could visit people who are sick or in nursing home. Many of us forget how luck we are and how much support we have. When we reach out to others, we sometimes realize how our lives have been blessed. When you are aware of all the blessing that you have received, you can understand your true ability to make a difference. Service is a spirit for living as well as a set of actions. You live your life purpose every day. It's not just when you are volunteering at church or the local food bank. It's every time you interact with anyone. Through your actions, your words and your smiles, you have the capability to either uplift someone or put them down.

Whether it's at work, in traffic, in the line at the grocery store, or at a concert, you have an opportunity to serve or change the world. Your efforts don't have to be extraordinary, but your life certainly will be. Question: We can infer from the passage that the author _ . Yes or no, is the answer "values voluntary work very much"?
