Read the following article and select the best answer. Article: Australia has promised to introduce the most comprehensive carbon trading program outside Europe in 2010. The government in Canberra plans to cut greenhouse gas emissions by at least five percent by 2020, but it could make bigger reductions if other countries agree to tougher targets. The Australian government warns that without tough environmental measures the country could lose key industries and jobs. Climate Change Minister Penny Wong says the economy is under threat and decisive action is needed. Central to the government's climate change plan is a carbon emissions trading program that will be introduced within two years. It would involve one thousand of the nation's biggest companies and would cover about three-quarters of Australia's greenhouse gas emissions. Many scientists believe that greenhouse gases, such as carbon dioxide and methane, contribute to global warming. Many of them are released by burning fuels such as coal and oil. Companies will be required to buy permits for each ton of carbon they emit, although big polluting exporters will receive up to 90 percent of their carbon licenses free. Many business leaders want the government to delay the plan because of the current global financial crisis, which is slowing the Australian economy. Peter Anderson from the Australian Chamber of Commerce and Industry says it is irresponsible to bring in a carbon trading plan now. Environmentalists, on the other hand, say Prime Minister Kevin Rudd has not properly addressed the threat of climate change. Activists had sought a minimum emissions cut of 25 percent. Instead, the Rudd government aims to cuts carbon emissions by at least five percent of 2000 levels by 2020. That amount could rise to 15 percent, if future global agreements set such a target. Ray Nias of the environmental group WWF says Australia will pay the price for low targets. "This is a deeply, deeply disappointing target," Nias said. "It commits Australia to long-term climate change. It will make Australia's ability to negotiate global... Question: Who most probably agrees to a higher goal of carbon emissions? - Penny Wong. - Peter Anderson. - Kevin Rudd. - Ray Nias.

Article: * Cliffs of Moher, Ireland Stretching for five miles along Ireland5s western coast, the Cliffs of Moher are a sight more than 300 million years in the making. At their highest, the cliffs soar an impressive 702 feet above the Atlantic Ocean, offering the million visitors who visit each year incredible views sure to leave hearts racing both from the beauty and the height. * White Cliffs of Dover,UK These famous cliffs along England's south-eastern coast are as rich in history as they are in beauty. They stand tall along the Strait of Dover, separating England from France and continental Europe. During World War I, the first bomb to hit the UK fell in Dover, and it served as a prominent location during WWII as well. And nowadays, the city is the best known for the beauty of its chalky white cliffs. * Mount Thor, Canada The name Mount Thor may inspire fear or respect -- as well it should, considering this is the steepest, tallest cliff in the world. Thor reaches an astonishing 4?101 feet above sea level, and the utter greatness of its vertical incline kept it from being successfully gone up until 1965. Today,it remains a challenging and popular place for rock climbers. ' * Cliffs of Etretat,France Located along France's Alabaster Coast, these cliffs offer more than just steep walls. Climb to the top and you'll have views of arched rock formations, as well as scenery that inspired the famous painter Claude Monet. At various points along the cliffs580-mile stretch, you can spot natural sculptures that are said to resemble an elephant, among other things. Question: If you want to challenge yourself as a rock climber, the t choice is - Cliffs of Etretat - White Cliffs of Dover - Ckiffs of Moher - Mount Thor

Q: Read the following article and select the best answer. Article: In jokes, the chicken only crosses the road. In Australia,cane toads use roads to travel. A new study finds that Cane toads are using roads to spread across the continent. They take shelter overnight close to the opencorridors , and then hit the road each evening in their damaging way. Cane toads were brought into Australia from Hawaii in 1935 to control the spread ofbeetles that were destroying Australia's sugar cane crop. _ are now moving into new places at the speed of 30 miles a year. Toads can grow as large as dinner plates and can weigh up to 4.5 pounds. Their heads and backsides are covered with rows ofwarts . They are known to kill snakes, lizards and other animals, including pet dogs. They have no natural enemy in Australia. According to a research, toads make slower progress through thick plants than along open spaces and they hop alongside roads and fences whenever possible. Toads use long corridors that are well-suited for them to travel long distances. Another study recently found that toads haveevolved longer legs in recent years and that this is also helping them in their spread. Efforts to kill toads have been largely unsuccessful, although scientists tried their best. Another new finding suggests ways to slow down its population. For example, roadside borders can be changed to make them less attractive to toads, or allowing thick plants to grow along the sides of highways, thus forcing toads onto the road of themselves. Question: At first, cane toads were brought to Australia to _ . - kill snakes, lizards and other animals - stop pet dogs from spreading - protect the sugar cane crop - hate a scientific research
A: protect the sugar cane crop

*Question*
Read the following article and select the best answer. Article: More than a decade ago, cognitive scientists John Bransfgord and Daniel Schwartz, both then at Vanderbilt University, found that knowledge was not the ability to retain facts or apply previous knowledge to a new situation but a quality they called "preparation for future learning." The researches asked fifth graders and college students to create a recovery plan to protect bald eagles from extinction. Shockingly, the two groups came up with plans of similar quality (though the college students had better spelling skills). From the standpoint of a traditional educator, this outcome indicated that schooling had failed to help students think about ecosystems and extinction, major scientific ideas. The researches decided to go deeper, however. They asked both groups to generate questions about important issues needed to create recovery plans. On this task, they found large differences. College students focused on critical issues. The college students had cultivated the ability to ask questions, the foundation of critical thinking. They had learned how to learn. Museums and other institutions of informal learning may be more suitable to teach this skill than elementary and secondly schools. At the Exploratorium in San Francisco, we recently studied how learning to ask good questions can affect the quality of people's scientific inquiry. We found that when we taught participants to ask "What if?" and "How can?" questions that nobody present would know the answer to and that would spark exploration, they engaged in better inquiry at the next exhibit--asking more questions, performing more experiments and making better interpretations of their results. Specially, their questions became more comprehensive at the new exhibit. This type of learning is not limited to museums of institutional settings. Informal learning environment tolerate failure better than schools. Perhaps many teachers have too little time to allow students to form and pursue their own questions and too much ground to cover in the curriculum. But... Question: What does the author seem to encourage educators to do at the end of the passage? - Train students to think about global issues. - Design more interactive classroom activities. - Make full use of informal learning resources. - Include collaborative inquiry in the curriculum.
**Answer**
Make full use of informal learning resources.
