I'm taking a test and have to guess the right answer to the question after the article. Article: What's the greenest place in America? If you answered something like the warm sunlight of Santa Barbara, you'd be wrong. The greenest place in America has almost no sign of nature-- the buildings outnumber the trees-- and the air isn't all that great. What it has is density and efficiency-- the twin qualities that finally define green in the global warming time. Applying those standards,the greenest place in America is New York City-- particularly,the overcrowded,overpriced island of Manhattan, which produces 30% less per-capita greenhouse gas than that of the nation. It's that density that makes Manhattan so green. Manhattan's population density is 800 times the national average. Density comes with negatives,certainly-- small living spaces,air pollution-- but it also enables amazing efficiencies.Over 80% of Manhattanites travel to work by public transport, by bike or on foot-- compared to an average of about 8% everywhere else in the country. Manhattan's apartment buildings are far more energy-efficient than the houses in the suburbs. What's true of New York City is more or less true of other American urban areas, which explains why a growing part of the environmental movement now focuses on greening cities, hoping to attract more Americans back downtown. There's an effort to make cities more sustainable ,by improving public transport,reducing air pollution and upgrading energy efficiency. But even more important, it is quite urgent to change decades of government policies that have been in favor of the suburbs,with disastrous consequences for energy,the environment and the climate. That's exactly the difficult point. For all the high efficiency and convenience and richness of living in a city,there are disadvantages too.New York,for example,has some of the highest childhood asthma rates in the U.S. So it's welcome news that New York has continued to push its P1aNYC scheme, a long-term program to make the city greener and more sustainable over the next decades. Recently _ announced an update to the plan that... Question: We can infer from the passage that _ . Options: A: New Yorkers have urged the city government to carry out green policies B: the public transport and living space are quite satisfactory in New York C: life in the countryside is more comfortable and energy efficient than that in cities D: the significance of making cities greener is gained in promoting energy efficiency

I'm taking a test and have to guess the right answer to the question after the article. Article: I was walking along prefix = st1 /Orchard Roadwhen I realized a tall young man wearing a jacket and tie was following me. I noticed him because not many people wear a jacket and tie in the middle of a hot summer day, and I had already seen this man four times that afternoon.

I'm taking a test and have to guess the right answer to the question after the article. Article: It is often said that politeness costs nothing.In fact,it seems that a little more courtesy could save businessesPS5 billion every year. Frequently hearing the phrase "thank you" or "well done" means the same to staff as a modest pay rise,researchers say. Praise and encouragement also makes employees more likely to work hard and stay in their jobs,saving on the cost of finding replacements. A third of 1,000 workers surveyed by consulting firm White Water Strategies said they did not get thanked at all when they did well--and a further third said they were not thanked enough. In both cases,staff said they felt undervalued,meaning they were less likely to exert themselves and were more likely to look for employment elsewhere. The net result is around PS5.2 billion in lost productivity from employees who would raise their game if they felt more appreciated,White Water claimed According to the company,praising staff has the same motivational kick as a 1 per cent pay rise--and works out much cheaper for bosses. Three out of four employees said that regular acknowledgement by their boss was important to them,but only a quarter said they were actually given as much praise as they felt they needed. The survey found that those in blue-collar and manual jobs were less likely to be given any recognition for doing well. In regional terms,Scottish staff felt most undervalued.Four out of ten workers said they were never thanked and eight out of ten said they would like more praise.However,workers in the North-East are less impressed by being buttered up by the boss,as only 69 per cent said they felt the need to be told "well done"regularly. Older employees and women need the most reassurance,according to psychologist Averil Leimon,a director of White Water Strategies.She said that words of praise did more than create a pleasant place to work--they could even boost profits. Question: The main idea of the passage is that _ . Options: A: praise and encouragement may help employees work better B: workers are always demanding more praise and encouragement C: bosses in prefix = st1 /Scotlandusually praise and encourage their staff enough D: if undervalued employees will certainly look for employment elsewhere
