I'm taking a test and have to guess the right answer to the question after the article. Article: In the late 1500s, a large powerful gun was placed on top of the Signal Hill, in prefix = st1 /Newfoundland, to prevent attacks from the outside. Flags were also flown there to warn sailors of bad weather. It's fitting, then, the Italian Gulielmo Marconi should have chosen this site to receive the world's first radio signal -- in Morse code -- from England on December 12, 1901. Marconi, combining earlier ideas with his own, led us to a new communications age. For the next 50 years, until the appearance of television, radio ruled the air waves. Today, it's the TV that rules. No single person can say to have invented television. In 1884, the German Paul Nipkow invented a device that sent pictures mechanically , and in 1906, Boris Rosing, a Russian, used a ray and a disc to create the world's first TV system. Then in the early 1920s, another Russian, Vladimir Zworykin,invented a picture display tube. He took out a patent for color1 TV, even though it wouldn't be developed for another 25 years. In 1924, a Scot entered the scene -- John Logie Baird. He first succeeded in sending a moving picture and a year later got the first actual TV picture. In 1926, Baird showed TV in aLondonlaboratory. Two years later inNew York, Felix the Cat became the first TV star. TV excited everyone's imagination, but hardly anyone had a set, with just two thousand in use worldwide in the mid-1930s. Since the late 1940s, TV technology has developed very quickly. Computers may finally be combined with all televisions to give people a total all-in-one communications network. Today, it's possible to sit and watch TV in the middle of a forest or in the Arctic. It's surprising when one considers that Marconi was on Signal Hill in the same century. Question: When the writer says that today it is the TV that rules, he means that the TV _ . Options: A: has led to a new communications age B: is a major means of today's communication C: is a device invented with ideas from Marconi D: has replaced the radio in today's communication
(Answer)
B

I'm taking a test and have to guess the right answer to the question after the article. Article: Older fathers have uglier children, researchers have claimed after linking age to genetic mutations . The finding comes weeks after leading scientists reported children born to men over the age of 45 run a higher risk of having autism and mental disorders. With age, sperm -producing cells do not copy a man's DNA as effectively, leading to genetic mutations. Martin Fielder, an anthropologist at Vienna University, told the Sunday Times: 'Every 16 years the mutation rate doubles. Other researchers found 25 mutations per sperm in a 20-year-old, but at age 40 it is 65 mutations. By 56, it doubles again. The effect is very visible - someone born to a father of 22 is already 5-10 per cent more attractive than those with a 40-year-old father and the difference grows with the age gap. In contrast, women pass on a maximum of 15 mutations to their baby, regardless of age, according to the study published in the journal Nature. Surveying a group of six men and six women, researchers showed them each 4,018 photographs of 18-20-year-old men and 4,416 of women the same age, and asked to assess their attractiveness. Those with older fathers were consistently considered less attractive. However, the children of older men, though less attractive, are likely to outlive their peers with younger fathers, it is claimed. Professor Lee Smith, a geneticist at Edinburgh University, told the Sunday Times other research found such children have longer telomeres - the caps on the end of chromosomes --- which are associated with longer life. But the mounting research connecting parents' age with autism is cause for concern, experts warn. Autism is an umbrella term for a range of developmental disorders that have a lifelong effect on someone's ability to interact socially and communicate openly. In the UK, around one in 100 adults is thought to be affected by autism, mostly men, caused by a combination of genetic and environmental factors. Researchers said men should be advised about the potential problems in order to help their personal... Question: Which of the following is TRUE according to the passage? _ Options: A: Aging is the cause of genetic mutations B: Mothers have less effect on their children's appearance than fathers C: Children born to younger fathers are more attractive in looks than those born to older fathers and the difference grows with the age gap D: Simon Cowell and Frank Skinner are mentioned as an example to show that older fathers have uglier children
(Answer)
C

I'm taking a test and have to guess the right answer to the question after the article. Article: Imagine you're in a dark room, running your fingers over a smooth surface in search of a single dot the size of this period, How high do you think the dot must be for your finger to feel it? Scientists have determined that the human finger is so sensitive it can detect a surface bump just one micron(l0-6m)"high. The human eye, by contrast, can't tell anything much smaller than100 microns.No wonder we rely on touch rather than eyesight when faced with a new roll of toilet paper. Biologically, touch is the mother of all sensory systems.It is an ancient sense in evolution: even the simplest single-celled living things can feel when something brushes up against them and will respond by moving closer or pulling away. It is the first sense aroused during a baby's development and the last to weaken at life's peak. Patients in a deep coma who seem otherwise lost to the world will show skin reaction when touched by a nurse. "Touch ,is so central to what we are that we almost cannot imagine ourselves without it," said Chris Dijkerman."It's 'not like eyesight, where you close your eyes and you don't see anything. _ .It's always there." Long ignored in favor of the sensory heavyweights of eyesight and hearing, the study of touch lately:: has been gaining new concern among scientists.They're exploring the effects of recently reported false touch impressions, of people being made to feel as though they had three arms, for example, with the hope of gaining the true understanding of how the mind works. Others are turning to touch for more practical purposes: to build better touch screen instruments and robot hands, a more well-rounded virtual life.. "There's a fair amount of research into new ways of offloading information onto our sense of touch," said Lynette Jones. "To have your cell phone buzzing (making a low sound) as opposed to ringing turned out to have a lot of advantages in.some situations." Touch is our most active sense, our means of seizing the world and experiencing it 'first hand. Dr.Susan Lederman pointed... Question: In the view of _ , movement is needed when we want to know something by touching. Options: A: the author B: Chris Dijkerman C: Lynette Jones D: Susan Lederman
