Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Scientists study the ocean in many different ways. Although many marine scientists focus on animals in the ocean, others seek to gain a better understanding of the ocean's chemical and physical components . Scientists are learning a great deal about the natural and human-caused processes that shape the ocean and its many life forms. Much of the present research focuses on how human activity influences the ocean. Clean water is a limited resource, and ocean pollution does harm to plant and animal health. Some scientists are now studying ocean water to find out just how contaminated it is. Scientists are also working on new methods to estimate the presence of poisons in the ocean, which will help them develop better techniques for cleaning up the water. Others look at how sea living things get used to poisons because poisonous sea life has an effect on humans too. For example, some seafood is poisoned, which may cause a threat to humans who eat it. Another type of marine scientist tries to learn more about the history of the ocean. Understanding the ocean's past tells scientists more about its patterns and cycles today and in the future. The ocean's past, which is recorded by deposits in the ocean floor, helps scientists understand such important matters as global climate change and other environmental differences. The more researchers learn about the history of the ocean and its relation to climatic and environmental changes, the more likely that they will one day understand what causes such changes. Other scientists are concerned with understanding how ocean systems work. The word systems refers to all the conditions and elements that are continually changing the ocean. Understanding these systems is necessary to protect the ocean and ensure the safety of its life forms. The cycles of ocean life also have an enormous effect on human life; for example, studying coastal waters is important because they provide much of the fish that humans eat. Marine geologists are earth scientists who work along the ocean... Question: According to the passage, we can know that one focus of marine geology is _ . Options: A: the destruction of the ocean plants B: the form of the ocean floor C: the development of ocean living things D: the history of the ocean
Answer: D

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Lisa was running late. Lisa, 25, had a lot to do at work,plus visitors on the way: her parents were coming in for Thanksgiving from her hometown. But as she hurried down the subway stairs, she started to feel uncomfortably warm. By the time she got to the platform, Lisa felt weak and tired-maybe it hadn't been a good idea to give blood the night before, she thought. She rested herself against a post close to the tracks. Several yards away, Frank, 43, and his girlfriend, Jennifer, found a spot close to where the front of the train would stop. They were deep in discussion about a house they were thinking of buying. But when he heard the scream, followed by someone yelling, "Oh, my God, she fell in!" Frank didn't hesitate. He jumped down to the tracks and ran some 40 feet toward the body lying on the rails. "No! Not you! " his girlfriend screamed after him. She was right to be alarmed. By the time Frank reached Lisa, he could feel the tracks shaking and see the light coming. The train was about 20 seconds from the station. It was hard to lift her. She was just out. But he managed to raise her the four feet to the platform so that bystanders could hold her by the arms and drag her away from the edge. That was where Lisa briefly regained consciousness, felt herself being pulled along the ground, and saw someone else holding her purse. Lisa thought she'd been robbed. A woman held her hand and a man gave his shirt to help stop the blood pouring from her head. And she tried to talk but she couldn't, and that was when she realized how much pain she was in. Police and fire officials soon arrived, and Frank told the story to an officer. Jennifer said her boyfriend was calm on their 40-minute train ride downtown-just as he had been seconds after the rescue, which made her think about her reaction at the time. "I saw the train coming and I was thinking he was going to die." she explained. Question: How did Frank save Lisa? Options: A: By lifting her to the platform. B: By helping her rise to her feet. C: By pulling her along the ground. D: By dragging her away from the edge.
Answer: A

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: In earliest times, men considered lightning to be one of the great mysteries of nature. Some ancient people believed that lightning and thunder were the weapons of the gods. In reality, lightning is a flow of electricity formed high above the earth .A single flash of lightning 1.6 kilometers long has enough electricity to light one million light bulbs. The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752.In the same year he also built the first lightning rod . This device protects buildings from being damaged by lightning. Modern science has discovered that one stroke of lightning has a voltage of more than 15 million volts .A flash of lightning between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second . Scientists judge that there are about 2, 000 million flashes of lightning per year. Lightning hits the Empire State Building in New York City 30 to 48 times a year. In the United States alone it kills an average of one person every day. The safest place to be in case of an electrical storm is in a closed car.Outside, one should go to low ground and not get under trees.Also, one should stay out of water and away from metal fences.Inside a house, people should avoid open doorways and windows and not touch wires or metal things. With lightning, it is better to be safe than sorry! Question: Which of the following is NOT true? Options: A: In the US about one person per day dies from lightning. B: The Empire State Building frequently gets hit by lightning. C: Swimming during a thunderstorm is a good idea. D: A closed car is the best place to be during an electrical storm.
