Read the following article and select the best answer. Article: Five years ago ,David Smith wore an expensive suit to work every day. "I was a clothes addict ," he joked . "I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled." Today David wears casual clothes--khaki pants and a sports shirt--to the office. He hardly even wears a necktie. "I'm working harder than ever," David says, "and I need to feel fortable." More and more panies are allowing their office workers to wear casual clothes to work. In the United States, the change from formal to casual office wear has been gradual. In the early 1990s, many panies allowed their employees to wear casual clothes on Friday (but only on Friday). This became known as "dress-down Friday" or "casual Friday" . "What started out as an extra one-day-a-week benefit for employees has really bee an everyday thing." Said business consultant Maisly Jones. Why have so many panies started allowing their employees to wear casual clothes? One reason is that it's easier for a pany to attract new employees if it has a casual dress code . "A lot of young people don't want to dress up for work," says the owner of a software pany, "so it's hard to hire people if you have a conservative dress code." Another reason is that people seem happier and more productive when they are wearing fortable clothes. In a study conducted by Levi Strauss and pany ,85% of employers said that they believe that casual dress improves employee morale. Only 4% of employers said that casual dress code has a negative impact on productivity .Supporters of casual office wear also argue that a casual dress code helps them save money . "Suits are expensive ,if you have to wear one every day," one person said. "For the same amount of money ,you can buy a lot more casual clothes." Question: David Smith refers to himself as having been "a clothes addict" because_. - he couldn't stand a clean appearance - he often wore khaki pants and a sports shirt - he wanted his clothes to look neat all the time - he didn't want to spend much money on clothes
he wanted his clothes to look neat all the time

Read the following article and select the best answer. Article: Rail passengers are being forced to pay thousands of pounds more in fares as a result of poor advice from the national telephone helpline and individual stations, a consumer organisation reveals today. Research by Which? found that in some cases passengers are being charged almost double the cheapest price because of errors made by staff . Which? asked 25 questions of both station staff and the National Rail Enquiries (NRES) helpline. Only half of the 50 questions were answered correctly. If customers had followed all the advice given ,they would have been PS1,263.60 worse off . Bad advice was given for the cheapest fare for a single journey between London and Grantham .For a ticket bought on the day of travel, both NRES and a King's Cross station clerk quoted GNER'sPS44.50 fare ,ignoring a Hull Trains service which leaves 10 minutes earlier and costs just PS20. Some of the most costly misinformation was given for journeys where season tickets should have been recommended .Passengers making a return journey between Swindon and Penzance twice in a week could buy a ticket from one company for PS70 which would cover all the travel. But both NRES and station staff quoted PS67 for each journey, making PS134.However, the NRES website proved to be a much more reliable source of information . Which ? also checked "the earlier you book, the cheaper the ticket" claims by five companies and found this was not always the case .On some services, prices went up and down _ . Ithiel Mogridge,52,gave one example of poor advice :"Last Christmas I found my brother a ticket on the _ to travel from Blackburn to Yate. While the direct route wasPS51, this one involved a change in Newport and cost just PS21. I emailed the details to him and his partner. They went to Blackburn station ,where the clerk insisted the fare was PS51." Malcolm Coles, editor of _ ,said. "Staff training needs to be improved. In the meantime ,we've designed a checklist, available at _ " Question: When the author said that customers "would have been PS1,263.60 worse off", he was telling us that customers would have - saved PS1,263.60 if they had followed the advice - spend PS1,263.60 more than the lowest price - used PS1,263.60 for the survey of 25 questions - been cheated of PS1,263.60 from the poor advice
(Answer)
spend PS1,263.60 more than the lowest price

Read the following article and select the best answer. Article: Large numbers of children in Britain are missing out on the natural world, a study from the RSPB (Royal Society for the Protection of Birds) suggests. The three-year project found that only 21 % of children aged 8 --12 were "connected to nature". Girls were much more likely than boys to be exposed to the great outdoors, while children in Wales had the lowest score across the UK. The RSPB says that a perception among some adults that nature is dangerous or dirty could be holding children back. There has been an increasing amount of research in recent years underlining the lack of contact and experience with nature among modern children. Some have argued that this is having a negative impact on their health, education and behaviour. The RSPB says its new study is the first to quantify the scale of British children's exposure, or lack of it, to the natural world. They came up with a definition of what "connected to nature" actually means and then deve -loped a questionnaire with 16 statements designed to assess the level of connection among children. Some 1, 200 children from across the UK were asked to agree or disagree with these statements. Only 21 % of children in the UK had a level of connection with wildlife and the natural world that the RSPB believes should be realistic and achievable for all youngsters. This "realistic and achievable" value is based on the average scores of children visiting RSPB sites or who are junior members of the organization. One interesting finding was the gender difference. While 27 % of girls were at or above the "realistic and achievable" target, only 16 % of boys were at the same level. "We need to understand these differences," Sue Armstrong Brown, head of conservation at the charity, told BBC New. "Whether boys and girls are scoring differently on different questions, are girls more empathetic to nature than boys for instance? We need to analyze the data to find that out." The report also stressed significant regional differences. Only 13% of children in Wales... Question: How did the RSPB assess the level of nature connection among children? - By doing an experiment. - By carrying out a survey. - By running a test. - By visiting wildlife.
