Read the article and select the best answer. Article: In the United States alone,over 100 million cell-phones are thrown away each year.Cell-phones are part of a growing mountain of electronic waste like computers and personal digital assistants.The electronic waste stream is increasing three times taster than traditional garbage as a whole. Electronic devices contain valuable metals such as gold and silver.A Swiss study reported that while the weight of electronic goods represented by precious metals was relatively small in comparison to total waste,the concentration of gold and other precious metals was higher in So-called e-waste than in naturally occurring minerals. Electronic wastes also contain many poisonous metals.Even when the machines are recycled and the harmful metals removed,the recycling process often is carried out in poor countries,in practically uncontrolled ways which allow many poisonous substances to escape into the environment. Creating products out of raw materials creates much more waste material,up to 100 times more,than the material contained in the finished products.Consider again the cell-phone,and imagine the mines that produced those metals,the factories needed to make the box and packaging it came in.Many wastes produced in the producing process are harmful as well. The U.S Environmental Protection Agency notes that most waste is dangerous in that"the production, distribution,and use of products-as well as management of the resulting waste-all result in greenhouse gas release." Individuals can reduce their contribution by creating less waste at the start-for instance,buying reusable products and recycling. In many countries the concept of extended producer responsibility is being considered or has been put in place as an incentive for reducing waste.If producers are required to take back packaging they use to sell their products,would they reduce the packaging in the first place? Governments' incentive to require producers to take responsibility for the packaging they produce is usually based on money.Why,they ask,should cities or... Question: What docs the passage mainly talk about? Options: A: The increase in e-waste. B: The creation of e-waste. C: The seriousness of e-waste. D: The management of e-waste.

Q: Read the article and select the best answer. Article: FOR most people, life without plants is unimaginable. They feed us, clean up our air and brighten up our gardens. But what if someone told you that even our smartphones can benefit from plants? Meet the scientists from the Freiburg University of Mining and Technology in Germany. According to reports from Reuters, they have come up with a way to take the important element germanium from plants. The element was first discovered in Germany (hence the name) and was used to develop the first transistor because it can transport electricity very quickly. Nowadays, silicon-germanium alloy plays an important role in making computers, smartphones and fiber-optic cables . Although germanium can be found in soil around the world, it is difficult to extract . In the traditional process, people take the material after zinc mining or burning coal. But the Freiburg scientists decided to fall back on the natural world. Biology professor Hermann Heilmeier is one of the scientists who are using common plants for this uncommon process. "Different energy crops are being planted, for example, sunflowers, corn ... we want to use them for phytomining. In German we call it 'mining with plants'." Others have used this method in the past with metals like gold and copper . But in their study, the Freiburg scientists brought germanium from the soil into the roots and shoots of the plants, harvested them and then took the element from the plants. The process did not cost too much because germanium can be taken after plants are processed for use as biogas . So many of the costs are already covered in existing biogas plants. However, there is still a lot of work to do before we can all experience the benefits. At the moment germanium can only be harvested in very small amounts, just a few milligrams per liter. Now scientists are working on different plants to improve this. "As is so often the case, industry is still waiting because they want to see everything already working. Then they say, 'We'll have it.' But of course we have... Question: Which of the following statements would Professor Martin Bertau agree with? Options: A: Many businesses have already started contributing money to this research. B: Industry and science have stronger and closer connections than is generally expected. C: People from related industries showed no interest in extracting germanium from plants. D: Germanium has to be extracted from plants in large quantities before this type of extraction becomes industrialized.

Read the article and select the best answer. Article: Glacier National Park in Montana shares boundaries with prefix = st1 /Canada, an American Indian reservation, and a national forest. Along the North Fork of the Flathead River, the park also borders about 17,000 acres of private lands that are currently used for ranching, timber, and agriculture. This land is an important part of the habitat and migratory routes for several endangered species that frequent the park. These private lands are essentially the only ones available for development in the region. With encouragement from the park, local landowners initiated a landaus planning effort to guide the future of the North Fork. The park is a partner in an interlocal agreement that calls for resource managing agencies to work together and with the more than 400 private owners in the area. A draft plan has been prepared, with objective of maintaining traditional economic uses but limiting new development that would damage park resources. Voluntary action by landowners, in cooperation with the park and the county, is helping to restrict small lot subdivisions, maintain wildlife corridors, and minimize any harmful impact on the environment. The willingness of local landowners to participate in this protection effort may have been stimulated by concerns that congress would impose a legislative solution. Nevertheless, many local residents want to retain the existing character of the area. Meetings between park officials and landowners have led to a dramatically improved understanding of all concerns. Question: The passage mainly discusses _ . Options: A: the endangered species in Glacier National Park B: the protection of lands surrounding Glacier National Park C: conservation laws imposed by the state of Montana D: conservation laws imposed by Congress
