Many of the world's countries have reached or are approaching zero population growth (ZPG) .Nearly all such lands are economically well developed.They include much of Europe(including Russia),the United States,Canada,Japan.and Australia.As the rate of natural increase(RNI)declines,two things happen.First,the population begins to decline if the loss is not balanced by immigration.Second,a country's population ages because there are fewer births. Is achieving ZPG good or bad? What happens when a country's population begins to drop? Many people,after all,believe that population decline is a good thing.But is it good for everyone? Does everyone agree? An aging population can create many problems.Senior citizens require more health care and medical attention.Rather than paying into retirement programs,they begin to draw from their pensions.In the US,the Social Security program,according to many experts,will be used up by 2018.It will pay out more money than it takes in.Additionally, a great number of jobs go begging in search of people willing or entry. level positions that pay low wages.With an able to do them.Many of these jobs are aging population,who will fill them? At the other extreme,some positions require a large number of training and highly specialized skills.Who will fill these positions as retirees leave the workforce? The answer to the problem of declining and aging population is simple:increased migration.Today many people,particularly those from less developed countries,are migrating in search of employment.Many are willing to take jobs that cannot(or will not) be filled by _ .Others are well educated and highly skilled.Both groups contribute to a country's economy progress in many ways.Further, they add to the richness of a country's culture.Of greatest importance,perhaps,is the fact that they have become absolutely necessary to the economy of many lands.As you can see,for many countries and for most immigrants,migration is a win--win situation. In the writer's view,which of the following statements is TRUE? A) Not everyone agrees that achieving ZPG is absolutely good. B) Achieving ZPG is every country's aim in spite of its side effects. C) Achieving ZPG is bad for senior citizens. D) Achieving ZPG is good for employment.

A car that runs on coffee is unveiled(shown to the public for the first time)today but at between 25 and 50 times the cost of running a car on petrol, the invention won't please any motor industry accountants. Nicknamed the Car-puccino, it has been created using a 1988 Volkswagen Scirocco bought for PS400 and it was chosen because it looked like the time-traveling DeLorean in the movieBack To The Future.The car will be driven the 210 miles between Manchester and London powered only by roasted coffee granules .It has been built by a team from the BBC1 science programme Bang Goes The Theory and will go on display at the Big Bang science fair in Manchester to show how fuels other than traditional petrol can power vehicles. The team calculates the Car-puccino will do three miles per kilo of ground coffee -- about 56 cups of espressos per mile.The journey will use about 70 kilos of ground coffee which, at supermarket prices of between PS13 and PS26 a kilo depending on brand and quality, will cost between PS910 and PS1,820, or between 25 and 50 times the PS36 cost of petrol for the journey.In total, the trip will cost 11,760 espressos, and the team will have to take 'coffee breaks' roughly every 30 to 45 miles to pour in more granules.They will also have to stop about every 60 miles to clean out the 'coffee filters' to rid them of the soot and tar which is also generated by the process.So despite a top speed of 60mph, the many stops mean the going will be slow, with the journey taking around ten hours. Sadly, the inventors will still have to pay duty on their coffee fuel---even though tax collectors at Her Majesty's Revenue and Custom haven't yet worked out how much. Nick Watson, producer of Bang Goes The Theory, said, "Coffee, like wood or coal, has some carbon content so you can use it as a fuel.The coffee needs to be very dry and in granules to allow the air to move through the pile of coffee as it burns.The brand doesn't matter." He said the same technology could be used to power a car on other unusual... Why can coffee be used as a fuel? A) It looks like wood or coal. B) It contains some carbon content. C) It is very cheap. D) It is much better than woodchips or nut shells.
