Ques: Article: Marriages improve after children grow up and move out,according to an academic study,which suggests an" empty nest" is not always a bad thing. Popular wisdom has it that parents' relationships may suffer once their young fly the coop,because they feel they have lost their purpose in life.However, a new study by researchers at the University of California, Berkeley,has found that many couples actually feel happier when their children leave home because they are able to enjoy spending time together. In total,123 American mothers born in the 1930s were tracked for 18 years and asked to rate their satisfaction levels shortly after marrying, when they were bringing up babies,once their children reached their teenage years and finally at age 61,when almost all had" empty nests". Although not all said they were happier in general,most claimed their marriages had improved since their children had left home.Researchers believe this is not just because the spouses were spending more time together, but because they were able to enjoy each other's company more. One of the participants in the study, which is published in the journal Psychological Science,said:"Once the kids grow up...there's some of that stress removed...that responsibility removed,so things are a little more relaxed.'' Psychologist Sara Gorchoff, who carried out the investigation,said:"The take-home message for couples with young children is' hang in there'."Her co-author Oliver John added:"Don't wait until your kids leave home to schedule quality time with your partner." However, Dr Dorothy Rowe,from the British Psychological Society,said the effects of living in an "empty nest'" will depend on the parents'relationship with their children."If yod're just waiting for them to leave home so you Can get on with your life,then of course you'11 be pleased to see them go,"she said,''But if you've built your life around your children you'11 be terribly lonely."For some parents,their world falls apart when their Children leave.'' Question: Marriages improve after children fly the coop not because Yes or no, is the answer "many couples needn't work at all"?
Ans: No

Ques: Article: Home improvements such as using insulation and energy-efficient windows to lower heating and air-conditioning bills can greatly affect quality of life for low-income families. In 2014, researchers at New York's Columbia University interviewed 20 renters and homeowners in a low-income community in New York City before and after helping those people make energy-efficiency upgrades to their homes. The researchers found cold and heat caused not only extreme physical discomfort but health problems as well. Increased heating costs in winter months also used up so much of people's budgets they were forced to reduce their calorie intake. Additionally, poor air quality due to reduced air-conditioner use can increase the risk of illness. People whose homes were upgraded reported greater physical and mental ease, as well as energy savings of around 30 percent, averaging $20-$60 per month. Despite these benefits, a study by University of Chicago economists was critical of the cost-effectiveness of government programs that provide money for energy-efficiency upgrades for low-income households. Around 7,500 households in Michigan were given an average of $5,000 worth of free upgrades as part of a larger energy-efficiency program. The researchers found that the measures reduced the households' energy consumption by about 10-20 percent each month. However, these savings would amount to an average of just $2,400 over the lifetime of the upgrades--in other words, less than half the amount of the initial investment. The study also highlighted another issue regarding energy-efficiency programs. It had long been believed that low-income earners tended not to participate because they were unaware of the programs' existence. In the University of Chicago study, however, an intensive marketing campaign consisting of thousands of telephone calls and home visits raised the Michigan program's participation rate by only a few percentage points. The great expense and effort required for such a tiny effect indicates that it may be time to... Question: What do we learn about low-income earners from the Columbia University study? Yes or no, is the answer "They are forced to reduce their spending on food because of the high cost of heating in winter."?
Ans: No

Ques: Article: Thomas Edison was one of ten said to be the greatest genius of his age. There are only a few men in all of the history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be happy only because someone said he was a genius." There is no such thing as genius," Edison said. He said that what people called genius was mostly hard work. But Edison was a dreamer as well as a worker. From his earliest days as a child he wondered about the secrets of nature. Nature, he often said, is full of secrets. He tried to understand them; then, he tried to learn what could usefully be done with them. Edison enjoyed thinking. He knew that most people will do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking can give men enjoyment and pleasure. Edison could not understand how anyone could be uninterested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what ideas he had about life. "Work," he answered. "Discovering the secrets of nature and using them to make men happier." He said he had enough inventions in his mind to give him another 100 years of work. Question: The last sentence in the passage most probably implies _ . Yes or no, is the answer "life is too short for Edison to invent more for human beings"?
Ans: No

Ques: Article: Most shoplifters agree that the January sales offer wonderful opportunities for the hard-working thief. With the shops so crowded and the staff so busy, it does not require any extraordinary talent to help you to take one or two little things and escape unnoticed. It is known, in the business, as "hoisting". But the hoisting game is not what it used to be. Even at the height of the sales, shoplifters today never know if they are being watched by one of those evil little balls that hang from the ceilings of so many department stores above the most desirable goods. As if that was not trouble enough for them, they can now be filmed at work and forced to attend a showing of their performance in court. Selfridges was the first big London store to install videotape equipment to watch its sales floors. In October last year the store won its first court case for shoplifting using an evidence a videotape clearly showing a couple stealing dresses. It was an important test case which encouraged other stores to install similar equipment. When the balls first make an appearance in shops, it was widely believed that their only function was to frighten shoplifters. Their somewhat ridiculous appearances, the curious holes and red lights going on and off, certainly make the theory believable. It did not take long, however, for serious shoplifters to start showing suitable respect. Soon after the equipment was in operation at Selfridges, store detective Brian Chadwick was sitting in the control room watching a woman secretly putting bottles of perfume into her bag. "As she turned to go," Chadwick recalled, "she suddenly looked up at the 'balls' and stopped. She could not possibly have seen that the camera was trained on her because it is completely hidden, but she must have had a feeling that I was looking at her." "For a moment she paused, but then she returned to counter and started putting everything back. When she had finished, she opened her bag towards the camera to show it was empty and hurried out of the store." Question: The woman stealing perfume _ . Yes or no, is the answer "guessed that the detective had seen her"?
Ans:
No
