Q: Article: Amazingly, US crime figures have been falling for 20 years now. Of course, the big question is, why? And can any lessons be learnt? One reason could be the fall in the demand for the drug crack. During the 1980s, drug-related crimes soared, mostly caused by desperate crack users. However, according to professor Blumstein, co-author of The Crime Drop in America, news of the dangers of crack use caused its decrease and led to a fall in the number of drug-related crimes. Some say that the adoption of a zero-tolerance policy in many cities has helped lead to a fall in crime. In New York City, for example, mayor Rudy Giuliani imposed strict and automatic punishments for all crimes, including minor offences such as graffiti and littering. Many believe this has had a very strong deterrent effect. Another reason could be smarter policing strategies. Anti-theft measures and educating the community about car theft has helped see a drop in crimes in many areas. Also, the use of crime mapping schemes that can discover identify crime peaks in different parts of the city has helped police target hotspots. Another reason could be that more criminals are now behind bars. Sociologist John Conklin (from Tufts University) says a significant factor behind the fall in crime in the 1990s is the simple fact that many criminals are in jail. In his book Why Crime Rages Fell, he says sentencing was merciful in the 1960s and 1970s, when crime rose. But then more prisons were built and more offenders were imprisoned. Some have linked the fall in violent crime to a decline in children's exposure to lead in petrol. Jessica Wolpaw Reyes says, "Even low to moderate levels of exposure can lead to behavioral problems, reduced IQ, hyperactivity and youth crimes. You can link the decline in lead between 1975 and 1985 to a decline in violent crime 20 years later." Others say that the drop in crime has something to do with birth rates. According to statistics, birth rates peaked between 1957 and 1961, and the proportion of men in the US in their late teens and early 20s (the so-called "criminal age") was highest in the late 70s and early 80s. However, as time went on, the proportion of people in this age group decreased. Others claim that videogames have helped. A recent study has suggested that these games are keeping young people off the streets and therefore away from crime. Advocates of this argue that any effects the games may have in encouraging violent behavior is _ by the fact that the games keep potential criminals indoors and in front of the television. Some argue that the widespread use of camera phones makes some criminals think twice before committing a crime and getting filmed doing it. Also, many believe that the mass use of CCTV has also had an effect. Finally, some say that petty theft just isn't worth it any more. The resale value of second-hand goods such as televisions, cameras or clothes is now so low (or even non-existent) that most people see no point in stealing. So, what do you think?

Q: Article: Three years ago when I was still in the University, I also worked at a restaurant. An old man named Mr. Candido Filio was one of our regular customer at the restaurant. He was one of the most intelligent people I've ever known. Every Sunday the Philippine Star Newspaper had a special page for word puzzles and among his peers , Mr.Filio held the record for solving all the puzzles in less than five minutes. He encouraged me to solve them too, and for months and months, I did my best to beat him but failed. Then one Sunday, I did it! I was able to complete them before anyone else. Everyone cheered for me. He came up to me with a smile and said, " No one has ever beaten me before. You are the first. I'll have a prize for you tomorrow." The next day, he gave me a special Scrabble set. I would have never been able to afford one like that by myself. Then he said to me, " Kate, what do you think is man's final goal in life? Happiness, isn't it? You are happy and that should be considered as a success. Many people spend a lifetime searching for that. Be thankful that you have found it." I looked at him and knew that my life had changed, probably forever. He must have known that I always felt sad about not having much money. He encouraged me to learn the game and love words. And true to his words, I was never able to beat him again.
