In this task, you're given an article, a question which often contains a blank, four options (associated with "A", "B", "C", "D") and the answer to that question. Your task is to classify whether the given answer is correct or not by providing "Yes" or "No", based on the article.

Article: Most of the time, the ground feels solid beneath our feet. That's comforting. But it's also misleading because there's actually a lot going on underground. Masses of land (called plates) slip, slide, and bump against each other, slowly changing the shape of continents and oceans over millions and billions of years. Scientists know that Earth formed about 4. 5 billion years ago. They also know that our planet was hot at first. As it cooled, its outermost layer, called the crust , eventually formed moving plates. Exactly when this shift happened, however, is an open question. Now, an international group of researchers has an answer. They've found new evidence suggesting that Earth's crust started shifting at least 3.8 billion years ago. The new estimate is l. 3 billion years earlier than previous ones. Not long before 3. 8 billion years ago, lots of small planets were hitting Earth, keeping its crust in a hot, melting state. After the hard crust formed, much of it sank at various times into the planet's hot insides. There, it melted before returning to the surface. In some places, however, the crust never sank. One of the oldest such places is in Greenland, in an area called the Isua supracrustal belt. The rocky crust there is between 3. 7 and 3. 8 billion years old. The belt was once part of the seafloor, but now it is exposed to air. The researchers recently took a close look at the Isua supracrustal belt. They noticed long, parallel cracks in the rock that have been filled in with a type of volcanic rock. To explain this structure, the scientists propose that tension in the crust caused the seafloor to crack open long ago. Hot, liquid rock oozed from deep inside Earth to fill the cracks. Finally, the whole area cooled, forming what we see today. That explanation, plus chemical clues inside the rock, suggests that the Isua supracrustal belt was once part of plate under the ocean, beginning around 3.8 billion years ago. "It's a fantastic case of solving a jigsaw puzzle ,"says one of the researchers. He notes that the puzzle was "a very difficult one because these rocks are all very old and have been badly ruined".
Question: What can we infer from the text?

Asnwer: B
No

Article: Pets are popular. They're good listeners, they encourage us to exercise, and they're always on our side when we argue with others. They can bring people comfort and pleasure. But it is important to keep in mind that pets can carry diseases that can make you sick. Washing your hands often -- especially after you touch, feed, or clean up a pet -- is the best way to keep yourself healthy and prevent the spread of disease. Be sure to clean your fingernails carefully every time you wash. You also can protect your health by wearing gloves while cleaning animal cages or cat litter boxes. Avoid washing your pet in the bathtub , but if you do, always disinfect the tub immediately afterward. Be sure to bring your pet to the hospital for examinations every two weeks or month and whenever your pet is sick or injured. You can do a few other things to keep yourself and your pet healthy. Only give your pet food that has been planned ahead for them. It's not a good idea to share your food with your pet. Human food (like chocolate) can make animals sick. Never feed your pet raw meat because it can carry germs that cause serious illness. And funny as it can be to see your dog or cat drinking from the toilet, don't let pets do this. It's bad for your pet's health! Give them clean, fresh water to drink at all times. Never give milk to cats. The only milk an animal should drink is from its mother. Cow's milk is not for pets, especially for cats, as _ makes them sick. Finally, some animals aren't pets. Don't take in a wild or abandoned animal as a pet because it may have diseases that could make you or your family sick. Instead, turn to an animal rescue group that is trained in helping sick or abandoned animals.

Article: Personality is, to large extent, inherent --A-type parents usually bring about A-type offspring. But the environment must also have a profound effect, since if competition is important to the parents, it is likely to become a major factor lives of their children. One place where children _ A characteristics is school, which is, by its very nature, a highly competitive institution. Too many schools adopt the "win at all costs" moral standard and measure their success by sporting achievements. The current passion for making children compete against their classmates or against the clock produces a two-layer system, in which competitive A types seem in some way better than their B-type fellows. Being too keen to win can have dangerous consequences: remember that Pheidippides, the first marathon runner, dropped dead seconds after saying,"Rejoice, we conquer!". By far the worst form of competition in school is the disproportionate emphasis on examinations. It is a rare school that allows pupils to concentrate on those things they do well. The merits of competition by examination are somewhat questionable, but competition in the certain knowledge of failure is positively harmful. Obviously, it is neither practical nor desirable that all A youngsters change into Bs. The world needs types, and schools have an important duty to try to fit a child's personality to his possible future employment. It is top management.
