I'm taking a test and have to guess the right answer to the question after the article. Article: A blue hole is a flooded sea cave with a hole that opens up at the land's surface. These cave systems form in carbonate rock, often on islands. Some blue holes have very special rock formations and water chemistry. Far below sea level, they contain some of the harshest environments on Earth, with no oxygen and no light. Yet these areas are filled with life forms that have adapted to the extreme conditions. Information gathered from these blue holes is helping scientists to increase their understanding of biology, archaeology and geology. But exploring these blue hole environments brings danger as well as discovery. Blue holes get their name from the color1 some have when seen from the air. The color1 is usually a reflection of the sky on the water. But not all of these cave systems have blue surfaces. Some contain dark or muddy water. Blue holes are the result of erosion in which water breaks down rock. Rain falling thousands of years ago contained chemicals which slowly wore away at the limestone landmass. These holes were later filled with sea water as the sea level changed. The rising and falling of sea levels and the mixture of salt and fresh water further wore away at these cave formations. Blue holes are vertical caves. But they can also have horizontal cave formations that may be hundreds of meters long. These flooded cave systems can be found in the ocean, or they can be found inland. Ocean caves are affected by tides, so they always have water movement. But blue holes on land are very still. They have several layers of water, chemicals, and bacteria. The top layer of fresh water comes from rainfall. This layer acts like a cap on top of the layered mixture, and keeps out oxygen from the atmosphere. The fresh water floats on a denser layer of saltwater. Underneath this is a layer of poisonous hydrogen sulfide, produced by bacteria living in the water. Underneath this layer is anoxic seawater -- water that does not contain any oxygen. Underwater caves are probably one of the least explored ecosystems... Question: The exploration of blue holes can help us _ . Options: A: discover moue energy resources B: understand the origin of life on Farth C: learn about the movements of seawater D: get ready for the exploration of the ocean

I'm taking a test and have to guess the right answer to the question after the article. Article: LAST week, the College Board announced that it was revising the SAT (Scholastic Assessment Test) in an effort to make it more acceptable to test-takers, teachers, college admission officers and the public more generally. Test-takers who receive lower scores than they have hoped for are likely to be concerned about their academic future. It's no wonder that it's hard to discuss the test without negative feelings. The SAT isn't perfect. Like any test, it can be misused, and may reflect unequal educational opportunities. Even before the announcement of the SAT's redesign, experts were discussing the test's limitations. Writing in The New Yorker, Elizabeth Kolbert described its questions as limited: "Critical thinking was never called for, let alone curiosity or imagination." But the SAT provides an effective measure of a person's ability to reason through verbal and mathematical materials, a skill required in college. Although there are conflicting reports on the issue, a study published in the journal Educational and Psychological Measurement in 2011 found that the SAT can meaningfully add to the prediction of a student's first-year college academic performance, above his grades in high school alone. The fact that the SAT can help predict this is, to me, an astonishing achievement that cannot be ignored. We cannot afford to ignore tests because they fall short of perfection or make us uncomfortable. But there's a better way to make the SAT more acceptable in the long run: We should expand the types of tests we use so as to more fully reflect what students can do. What if, in addition to the SAT, students were offered new tests that measured more diverse abilities? For future artists or musicians, there are tests that measure creative thinking --a largely ignored ability by the SAT. For future engineers, there are tests that measure their sense of space. And new measures of "personal intelligence" -- the ability to reason about a person's motives, emotions and patterns of activities -- may also tell us...

I'm taking a test and have to guess the right answer to the question after the article. Article: From Sept. 1, Chinese children will be able to watch domestic cartoon programs during 5 p.m. every day, according to a regulation by prefix = st1 /China's TV watchdog. The State Administration of Radio, Film and Television (SARFT) has decided to ban all foreign cartoons during the "Golden hours", reported the Beijing News. No foreign cartoons or programs of introducing foreign cartoons can be shown during the period on all domestic cartoon channels, the regulation says. Only after 8 p.m. can foreign cartoons appear on TV, it requires. The regulation has been issued to local TV stations but the administration has not made it public, according to the newspaper. Cartoon programs co-produce by domestic and foreign producers will have to get approval from SARFT to show during 5 p.m. and 8 p.m. from Sept.1. The first foreign cartoon introduced to Chinawas a Japanese cartoon called "Astro Boy" series in 1981. Since then, a large quantity of foreign cartoons _ China. Incomplete surveys show about 80 percent of interviewed Chinese children like foreign cartoons according to the Southern Metropolis News. With the effects of regulations and establishment of 15 film and cartoon production bases in recent years, domestic cartoon industry attracted huge civil investment, resulting in a sharp rise of cartoon programs in 2005. However, due to the poor popularity among children, domestic cartoons found it hard to show during "golden hours", and even had troubles to get back the production costs. Moreover, it was the content of domestic cartoons that lost the audience, said the editorial, therefore improving the creation environment of cartoon makers is much wiser than such market-protecting measures. Finally it said it was reasonable and necessary to introduce system into the cartoon competition to protect the domestic industry, the complete prohibition of foreign cartoons and compulsory screening of domestic ones during popular hours was rather unreasonable. "This is a worrying, short-sighted policy and would not solve the... Question: What is the fact about Chinese children? Options: A: Chinese children prefer foreign cartoon films to domestic ones. B: Chinese children never watch domestic cartoon films. C: Chinese children prefer domestic cartoon films to foreign ones. D: Chinese children don't prefer foreign cartoon films.
