Question: Read the following article and select the best answer. Article: Watercress is positively packed with healthy vitamins and minerals. The writings of both the Romans and the Ancient Greeks record the consumption of watercress by all classes. Hippocrates, "the father of medicine", was so convinced that watercress was a great healer that he built his first hospital next to a stream so that he could grow a plentiful supply of the shiny green leaves for his patients. The Romans chewed watercress in large quantities, believing that it would cure baldness. They, too, looked with favor on watercress as a salad. Watercress sandwiches were traditionally a breakfast item in nineteenth-century Europe. The most basic type of watercress sandwich has two pieces of white bread with a mixture of butter and watercress greens . A nickname for the vegetable, in fact, was "poor man's bread", because watercress was often eaten on its own for breakfast by families that could not afford the bread to go with _ . Watercress is a member of the mustard family. It contains vitamins C(66mg per 100g), K and A, and is also a valuable source of minerals such as iron, potassium, copper and calcium. The mustard oils in its silky leaves and stems contain an ingredient known as PEITC. Recent research has proved that PEITC can prevent the growth of cancer cells and, in some cases, actually destroy them. The best watercress has silky green leaves without any marks and has undamaged stems, The older the plant, the darker are its leaves and the thicker its stems. This means a higher concentration of oils and vitamins. Young watercress, on the other hand, may be harvested after only twenty-eight days growth and has a milder taste. It is best to eat watercress fresh and raw , to keep more of its valuable nutrients, but it can be lightly cooked and used as an alternative to spinach--another dark green vegetable--in various recipes. From soups to salads, watercress is now considered around the world as a natural and healthy super food. Question: Compared with older watercress, young watercress _ - has lighter green leaves - contains more minerals - is better for medical use - is more suitable for eating raw
Answer: has lighter green leaves

Question: Read the following article and select the best answer. Article: It was a cold night in Washington, D. C., and I was heading back to the hotel when a man approached me. He asked if l would give him some money so he could get something to eat. I'd read the signs "Don't give money to beggars." So I shook my head and kept walking. I wasn't prepared for a reply, but he said, "I really am homeless and I really am hungry! You can come with me and watch me eat!" But I kept on walking. The incident bothered me for the rest of the week. I had money in my pocket and it wouldn't have killed me to hand over a buck or two even if he had been lying. Flying back to Anchorage, I couldn't help thinking of him. I tried to rationalize my failure to help by thinking government agencies, churches and charities were there to feed him. Besides, you're not supposed to give money to beggars. Somewhere over Seattle, I started to write my weekly garden column for The Anchorage Daily News. _ , I came up with an idea. Bean's Cafe, the soup kitchen in Anchorage, feeds hundreds of hungry Alaskans every day. Why not try to get all my readers to plant one row in their gardens dedicated to Bean's? Dedicate a row and take it down to Bean's. Clean and simple. The idea began to take off. Readers would fax or call me when they got something in their garden. Those who only grew flowers donated them. Food for the spirit. In 1995, the Garden Writers Association of America held their annual convention in Anchorage and after learning of Anchorage's program, Plant a Row for Bean's became Plant a Row for the Hungry. The original idea was to have every member of the Garden Writers Association of America write or talk about planting a row for the hungry sometime during the month of April. As more and more people started working with the Plant a Row idea, new changes appeared unexpectedly. Many companies gave free seed to customers and displayed the logo, which also appeared in national gardening publications. Row markers with the Plant a Row logo were delivered to gardeners to set apart their "Row for the... Question: Which do you think is the best title to the passages? - Plant a row for the hungry - How to help others - A story of a columnist - Not for fame and wealth
Answer: Plant a row for the hungry

Question: Read the following article and select the best answer. Article: A new study has found some secrets of people's understanding of large numbers. Researchers studied a group of people who were born deaf and never learned any spoken language or a formal sign language, but they have developed a gesture system to communicate with people around them. The gestures let them express approximate amounts, but not exact numbers. "Up to three, they're fine," says Elizabet Spaepen, a researcher at the University of Chicago and an author of the study. "But past three, they start to fall apart." In one test, Spaepen would knock her fist against a study participant's fist a certain number of times and then ask them to respond with the same number of knocks. "If I were to knock four times on their fist, they might knock on my fist five times," she says. The finding offers a clue to just how much language affects our understanding of numbers. That has been a big question since 2004, when other researchers published data on two tribes in the Amazon whose members also lack words for big numbers. "What they have are words that mean one and two," Spaepen says, "and then they have a word to mean many." Members of the Amazonian tribes also had trouble matching numbers larger than three or four. But some scholars felt that these earlier studies failed to prove that language was the reason. They pointed out that the tribes lived in groups that didn't use money and had no need for exact numbers. The new research appears to answer that criticism. "It proves that the kinds of problems in understanding numbers that we found in the Amazonian tribes are not due to just the cultural or environmental circumstances," says Peter Gordon of Columbia University, one of the researchers involved in the earlier studies.
