*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: A four-year study of 200 college students found that those who drink heavily and started drinking at an early age demonstrate poor decision-making skills, just like long-term, chronic  alcoholics. Researchers at the University of Missouri-Columbia believe early onset binge drinking negatively affects psychological development. The researches examined college students between the ages of 18 and 22. After three years, they tested them using the Iowa Gambling Test, which measures the tendency to make immediate (disadvantageous) or long-term (advantageous) choices. Based on the students' reported drinking habits, they were grouped into four categories: low binge drinkers, moderate binge drinkers, increasing binge drinkers and stable or high binge drinkers. "Students in the stable or high alcohol use category, who had longer histories of binge drinking, made riskier and less advantageous choices, which reflect problems associated with planning for the future," the researchers reported. The study also found that only students who started binge drinking when they were younger showed impairment on the task. "There is reason to think that heavy binge drinking during adolescence, when the brain is still rapidly developing, may have some negative legacy   on psychological development," said Kenneth J. Sher of MU's Midwest Alcoholism Research Center in a news release. "The interesting thing is that if we were to just look at binge drinkers and how impaired they are in the decision-making process as juniors, we'd really be obscuring  the important issue, which is how long they've been binge drinkers and / or how early they started." Question: Which category would make the most disadvantageous choice? Options: A: Low binge drinkers B: moderate binge drinkers C: Increasing binge drinkers D: Stable binge drinkers

I'm taking a test and have to guess the right answer to the question after the article. Article: The physicians in a hospital form the center of medical staff. But they could not provide effective medical care to their patients without the help of numerous other medical employees. From the viewpoint of the patients, the nursing staff is particularly important. Nurses are usually in close contact with patients as long as they are in the hospital. A nurse does not study for as many years as a doctor. however, each must be equally dedicated. Caring for sick persons requires a great deal of patience and concern. Most nurses work long days, and they often must work at odd hours or during the night. Under the supervision   of the head nurse, the nursing staff must provide nursing services on a 24-hour basis and attend to patients' needs. This responsibility continues around the clock, and so nurses must work in shifts. A shift is a period of duty, usually eight in length. The nurses on the ward rotate their shifts. Some take turns working night duty; others work odd shifts. A nurse must always be alert. She can never afford to be careless. This is true in all nursing situation, but it is especially true in the intensive care unit. Patients under intensive care are critically ill, and they must be monitored at all times. The nurses who do intensive care duty have one of the most demanding jobs in the hospital. Serving as a nurse can be a very rewarding job. But it is not an easy one. Not every person is suited to become a nurse. Only very dedicated people have chosen nursing as a profession. Question: The nursing staff   _  . Options: A: are central to the medical staff B: play an important role in caring for patients C: can work effectively without physicians D: are always in close contact with the patients

I'm taking a test and have to guess the right answer to the question after the article. Article: The oldest and most common source of renewable energy known to man, biomass  is one of the most important forms energy production in the United States and elsewhere. Since such a wide variety of biomass materials is everywhere --- from trees and grasses to agricultural and city --- life wastes ---biomass promises to play a continuing role in providing power and heat for millions of people around the world. According to the Union of Concerned Scientists(UCS), biomass is a kind of renewable energy source that produces no carbon dioxide , because the energy it contains comes from the sun. When plant matter is burned, it gives off the sun's energy. In this way, biomass serves as a sort of natural battery  for storing the sun's energy. As long as biomass is produced continuously ---with only as much grown as is used-- the "battery" lasts forever. According to the Energy Information Administration, biomass has been one of the leading renewable energy sources in the United States for several years running through 2007, making up between 0.5 and 0.9 percent of the nation's total electricity supply. In 2008---although the numbers aren't all in yet---wind power probably took over first place because of the rapid development of wind farms across the country. Producing power from biomass helps reduce some 11 million tons of carbon dioxide each year. Some homeowners also try to make their own heat by using biomass materials. Such practice may save homeowner's money, but it also produces a lot of pollution. So, the best way is to encourage power plants to use it. Question: Why does the author encourage power plants to use biomass? Options: A: To prevent the waste of energy. B: To increase production safety. C: To reduce pollution. D: To save money.

I'm taking a test and have to guess the right answer to the question after the article. Article: What makes a gift special? Is it the price you see on the gift cover? Or is it the look on the receiver's face when they receive it that determines the true value? What gift is worth the most? This Christmas I was thinking what to give my father. My dad is a hard person to buy for because he never wants anything. I pulled out my phone to read a text message from my mom saying that we were leaving for Christmas shopping for him when I came across a message on my phone that I had locked. The message was from my father. My eyes fell on a photo of a flower taken in Wyoming, and underneath a poem by William Blake. The flower, a lone dandelion  standing against the bright blue sky, inspired me. My dad had been reciting those words to me since I was a kid. That may even be the reason why I love writing. I decided that those words would be my gift to my father. I called back. I told my mom to go without me and that I already created my gift. I sent the photo of the cream-color1ed flower to my computer and typed the poem on top of it. As I was arranging the details another poem came to mind. The poem was written by Edgar Allan Poe; my dad recited it as much as he did the other. I typed that out as well and searched online for a background to the words of it. The poem was mainly about dreaming, and after searching I found the perfect picture. The picture was painted with blues and greens and purples, twisting together to create the theme and wonder of a dream. As I watched both poems passing through the printer, the white paper color1ing with words that shaped my childhood, I felt that this was a gift that my father would truly like. Christmas soon arrived. The minute I saw the look on my dad's face as he opened those swirling black letters carefully placed in a cheap frame , I knew I had given the perfect gift. Question: The author made the gift by  _  . Options: A: searching for poems online B: drawing the background by hand C: painting the letters in three color1s D: matching the words with pictures
