Article: When Caleb Forbes got his first job at an advertising company at the age of 20, he thought he would be at the company for years. But after seven months he was bored. Soon after that, Forbes moved to London. He took four different jobs at three companies over the next five years. Forbes wanted a better job and higher pay---he was never quite satisfied. Welcome to the world of a job hopper. Forbes's story isn't unusual these days and such frequent movement from one job to the next will become more common. The main reason: the nature of employment is changing. There are a lot more contracts and part-time jobs or flexible employment. That leads to people having a greater number of jobs. What's more, layoffs and pay freezes , among other things, have pushed people from one job to another. In some cases, a bad worldwide job market has limited opportunities for star employees, promoting them to seek new challenges at other companies. However, employers often think that if a person jumped from his last employer after a short period, he will likely do the same again --- there is a significant financial risk in hiring someone who leaves in short order. What's more, moving from company to company frequently doesn't mean workers are climbing the corporate ladder faster. In 2005, Monika Hamori, a professor at Spain's IE Business School, looked at CEOs at about 55 to see if those who moved around more frequently climbed the ladder faster. She found that executives who stayed with one company became CEOs after 23 years, while executives who changed companies many times became CEOs after 26 years. One reason: workers within the same organization tend to be promoted more frequently and be offered better jobs.
Question: How did Forbes feel about his first job at first?
Options: (A) It was easy. (B) It was boring. (C) It was satisfying. (D) It was dangerous.
Asnwer: D
No

Article: Have you seen a yellow-and-black salamander ? How about a scarlet frog? Scientists haven't spotted either species in more than 20 years. What happened to them? Are the creatures still out there, or are they extinct? Those are questions that scientists hope to answer. They recently set out around the world in search of those and other long-missing amphibians. An amphibian is an animal that spends part of its life in water and part on land. Frog, toads , and salamanders are amphibians. The experts are looking for about 100 species. They are searching at least 14 countries on five continents. They will look for the salamander in North America. They hope to find the scarlet frog in South America. They're also looking for species in Africa, Asia and Australia. Scientists are hopeful that they'll find the amphibians--and soon! If the creatures are out there, they may need help. Many amphibians are endangered. The animals face many dangers including pollution and diseases. People cut down the forests where they live. "If researchers can find the missing creatures, they might be able to figure out how to save them," explains expert Robin Moore. He began searching for the amphibians earlier this month. "This search will tell us a lot about how amphibians are doing," Moore told WR News. "I don't know what we will find, but that makes the search even more exciting." Lost in the Wild Scientists' hunt for missing amphibians is under way. Read about some of the species they hope to find. Turkestanian salamander This salamander is a mystery to scientists. Experts found a few of them more than 100 years ago, but none have been seen ever since. Gastric brooding frog Experts first discovered this frog in 1914 in eastern Australia. It may be extinct because of disease and habitat loss. Rio Pescado stubfoot toad Last sighting: 1995, in South America Scientists hope to find this spotted toad in rivers and rainforests in Ecuador. The animal faces threats including pollution and disease.
Question: Which of the following animals hasn't been seen for over a century?
Options: (A) Rio Pescado stubfoot toad. (B) Gastric brooding frog. (C) Turkestanian salamander. (D) Scarlet frog.

Article: Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers are letting students have a ball. By sitting on exercise balls instead of chairs , teachers find students' posture and attention improve. Dottie Pownall, a fifth-grade teacher in West Virginia, USA, has been using balls as chairs since December 2008. "The students love them", she says. Pownall took a survey of her students. She found that 80% of the students thought sitting on the balls helped them pay more attention to what they were learning. The teacher, Pisa Witt, felt so strongly about the use of balls as chairs, she started Witt Fitt. This company encourages the use of the balls. And the company educates not only teachers but also students on how to use them. "Our products are used in 24 states, three provinces in Canada, Puerto Rico and Japan," says Witt, " Research shows that sitting on the balls makes them sit up straighter . You can slouch on a ball," says Witt, "but it feels bad." Because the students are moving, their blood increases. That carries more oxygen( ) to the brain , so the kids have more energy and can pay attention longer. "Besides, they're fun." says Pownall.
