Read the following article and select the best answer. Article: Electricity, like clean water, is a resource that's often taken for granted. But last summer, when blackouts struck much of the northeastern US, Ontario and Rome, consumers on two continents were given a painful reminder of just how easily broken electricity supplies can be. The massive disorder stranded commuters, stopped freezers, shut down businesses and refocused attention on where most of the planet's power comes from:oil-and-gas-fired generators and nuclear plants, These sources not only pollute the environment but also make many consumers feel unacceptable health risks. Companies are trying to offer an alternative, clean energy from renewable resources that's plentiful and portable. Lifton's Medis Technologies, as well as companies like Hydrogenics and Nanosys, is tapping into fuel cells and dolor panels to give people power whenever and wherever they want it, free from dependence on local grids . The search for alternative energy is nothing new, but the current trend of innovators is focusing on the goal of making clean and sustainable power a mainstream commodity. For example, the fuel cell, which produces electricity from the chemical reaction between oxygen and hydrogen, has been around for about 150 years, though its commercial development did not begin until the 1960s and then only as part of NASA spacecraft. Today this technology is coming down to Earth in places like Tokyo; in nine European cities, from Stockholm to Porto, each operating three hydrogen-fuel-cell buses; and in Iceland, which is trying to create the first fuel free hydrogen economy by 2030. When hydrogen and oxygen molecules combine, the reaction produces heat and water. Fuel cells use this reaction to generate electricity. With the cell phone and gadget market in mind, Medis has developed a fuel cell with cheap components that produces little heat and effortlessly reduces waste water without turning to energy consuming pumps. Question: Which of the following statements is NOT true according to the passage? - Lifton's Medis Technologies is tapping into fuel cells and solar panels. - The fuel cell has been around for about 150 years. - The fuel cell's commercial development did not begin until the 1960s. - When hydrogen and oxygen molecules combine, the reaction produces o2 and H2O.
When hydrogen and oxygen molecules combine, the reaction produces o2 and H2O.

Read the following article and select the best answer. Article: There are two factors which determine an individual's intelligence, The first is the sort of brain he is born with , Human brains differ considerably , some being more capable others, But no matter how good a brain he has to begin with , an individual will have a low order of intelligence unless he has opportunities to learn, So the second factor is what happens to the individual- the sort of environment in which he is reared, If an individual is handicapped environmentally , it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable. The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark X. Being identical, the twins had identical brains at birth, and their growth, processes were the same, When the twins were three months old, their parents.died, and they were placed in separate foster homes, Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities, Mark was reared in the home of well-to -do parents who had been to college ,He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually, This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence, , Mark's LQ ,was 125.twenty-five points higher than the average and fully points higher than his identical brother Given equal opportunities, the twins, having identical brains , would have tested at roughly the same level Question: According to the passage , the average LQ is - 85 - 100 - 110 - 125
(Answer)
100

Question: Read the following article and select the best answer. Article: When I heard the piano, I walked to Mrs. Windsor's house and waited outside as I always did. That meant she was working with another student, and I was not supposed to bother them by ringing the bell. I stood against the wall and daydreamed what I'd rather be doing. "Almost anything", I sighed _ . I had been tutored enough to read, understand, and even write some musical compositions, but I just didn't have a gift for it. It didn't come to me naturally. I thought back to happier times when I was writing stories and acting them out with my friends, cutting up old clothes to make dresses that performers wear in plays, and building scenery out of old things we found. But Mrs. Windsor had offered to give me the lessons for free, so I felt my duty to try. The door opened and Wendy Barton came out. I walked in, sat down on the piano bench and began to sort through my sheet music. "Hello," I heard a voice behind me say softly. I turned around to see a little girl standing behind me, eating an apple. But before I could make any response, Mrs. Windsor walked into the room in her usual urgent manner and announced,"Jennifer, this is my niece, Pasha. Pasha, this is Jennifer. Pasha will be giving you your lesson today. I'm up to my ears in something else!" she then exited to the kitchen. Pasha set her apple down on the side table and slid beside me on the piano bench. "What piece do you like best?"she asked. "What do you mean?" I asked. "They're all the same to me. I don't know. "You mean you don't have a favorite?" "No, not really." Pasha looked at me, rather puzzled, then opened my sheet music to the beginning page and asked me to play. I arranged my fingers on the keys and studied the notes on the page for a moment. Then I frowned and concentrated to make the notes on the page match the finger movements. I have to admit I was a rather mechanical pianist. After about a page or two, Pasha gently put her hand on top of mine as if to calm my fingers. There was a long pause. "What are you hearing in the music?" I looked at...
