Question: Read the article and select the best answer. Article: Quickly ask yourself: What did you eat today? Now tell me how you actually feel. If you're complaining of stress, anxiety, depression, aches and pains, foggy thinking, or just a general lack of energy, a new medical theory will blow your mind. The chances are that those disease-like symptoms are all the result of what's called hidden food allergies . This is what Ken Drew found out when he was lucky enough to be recommended to medical practitioner Dr. Patel. Patel is considered something of a genius, and has been called a modern day Louis Pasteur. You've heard of him, of course--Pasteur figured out how to keep milk from getting spoiled. Dr. Patel is like a Louis Pasteur for keeping your body from getting spoiled from chronic diseases. "Foggy thinking, slightly constipated , heart pain,...you name it. It's part of getting old," you say. "It's just stress." Most of the body's immune defenses are all located in your stomach, so when you have a hidden food allergy and you expose yourself to harmful foods, your defenses malfunction and disease-carrying bacteria take over. Had you not eaten that one food you were allergic to for breakfast, you would never have got sick. Together, Dr Patel and Ken Drew have developed the Reverse My Disease program, which claims it can _ your body against diseases like arthritis , Alzheimer's, diabetes, heart disease and cancers. You won't need a prescription and there isn't any kind of medical procedure involved. There's no medical jargon, no complicated diet to do. What it does do is claim to tell you how to hack your body's natural defense system. Dr. Patel has remained under the radar of the entire medical establishment because his ideas are so threatening to doctors who don't want you to stop being sick enough for them to write you prescriptions. Those doctor visits cost you, so check out Reverse My Disease if you want to prevent disease by learning how to eat food that won't harm your body. Question: What is the author's attitude towards Reverse My Disease? Options: A: Unconcerned. B: Supportive. C: Cautious. D: Negative
Answer: B

Question: Read the article and select the best answer. Article: The United States covers a large part of the North American continent. Its neighbours are Canada to the north and Mexico to the south. Although the United States is a big country, it is not the largest in the world. In 1964, its population was over 185,000,000. When this land first became a nation, after winning its independence from England, it had thirteen states. Each of the states was represented on the American flag by a star. All these states were in the eastern part of the continent. As the nation grew toward the west, new states were added and new stars appeared on the flag. For a long time, there were 48 stars. In 1959, however, two more stars were added to the flag, representing the new states of Alaska and Hawaii. Indians were the first people of the land which is now the United States. There are still many thousands of Indians now living in all parts of the country. Sometimes it is said that the Indians are "the only real Americans". Most Americans come from all over the world. Those who came first in greatest numbers to make their homes on the eastern coast of North America were mostly from England. It is for that reason that the official language of the United States is English and that its culture and customs are more like those of England than those of any other country in the world. Question: Why is English the official language of America? Options: A: English is the Indian's native language. B: Most Americans come from all over the world. C: Most of the people who first settled in America were from England. D: Canada is America's nearest neighbour.
