Read the following article and select the best answer. Article: Millions of sports lovers are still thinking about one thing----the Winter Olympics in Sochi Russia. Close to 2900 men and women competed in the 2014 Winter Games about a month ago. The Olympics brought a lot of attention to Sochi, a city on the Black Sea, which is a popular area for vacation travelers. The area is known for its mild winters. At least $50 billion was spent on the 2014 Winter Games, making it the costliest Olympics in history. Seven billion dollars was spent on the 2010 Winter Games in Vancouver, Canada. Olympic officials chose Sochi to host the 2014 games almost seven years ago. At that time, Russian President Vladimir Putin said the games would cost about $13 billion. Yet the actual expenses exceeded his estimate. So where did all the money go? Some observers say the high cost is partly the result of security measures. Brian Jenkins, a terrorism expert from the RAND Corporation, gave the following explanation. There were anywhere between 70,000 and 100, 000 policemen and military troops deployed around the city. The main threat came from separatist and Islamist groups from the North Caucasus, especially from Chechnya and Dagestan. One group claimed responsibility for two suicide bombings in Volgograd last December. The attacks killed more than 30 people. The city is only about 600 kilometers away from Sochi. Bruce Hoffman is a terrorism expert from Georgetown University in Washington DC. He says the increased security made Sochi a difficult target for terrorists. It is thought that the terrorists' intention was to make life difficult for the Russians and to create some sort of incident that would take away the enjoyment. The last Olympians from around the world on Russian soil were in 1980. That was a year after Soviet troops invaded Afghanistan. More than sixty countries didn't take part in the Moscow Summer Games to show their anger. Question: According to the passage, why did the Sochi Winter Olympics cost so much? - Because it was held at an area popular for vacation travelers. - Because the Russian government wanted to make it the best ever held.[:] - Because security measures at Sochi were stricter than before. - Because the original plan was made 7 years before.
Because security measures at Sochi were stricter than before.

Read the following article and select the best answer. Article: You may have heard the popular saying, "there are always more fish in the sea". But as many new studies show, fish populations are changing, and not necessarily for the better. Consider the case of big, predatory fish. These giants, like sharks and cod , eat other smaller fish. Big fish are an important part of the marine ecosystem because they keep down the numbers of smaller fish. Without fish that eat other fish, populations of smaller swimmers would increase, eating more plants, and leaving less vegetation for other creatures, including future fish. As fierce as predators can be, they're no match for fishing technology. Many people love to catch predatory fish like sharks, cod and tuna, and new studies suggest that over-fishing is threatening these creatures near the top of the marine food chain. In one study, Villy Christensen and his colleagues looked at 200 past studies of marine life to learn how fish populations have changed over time. Christensen reported that between 1910 and 1970, the numbers of big predators decreased slowly, and that in 1970 their populations really started to drop. Around that time, fishing ships began using new tools that led to more fish being caught. The numbers have been falling quickly ever since. Reg Watson looked at the problem from the perspective of the fishermen. In the middle of the 20thcentury, Watson reported, fishing boats didn't go far from home, and most fish were caught near the shore. That was no longer true by the 1980s. By then, fishing had moved farther from shore, into the open oceans, and was helped by the development of new technologies. But since the 1990s, something has changed. Despite new technologies and more efforts, fishing operations have not continued to develop. Scientists study historical data to understand the present, and this research is needed to forecast the future of fish and fishing. And the forecast doesn't look good: large predator fish are becoming harder to find, and soon may disappear. Question: Why did the number of big predators begin to fall quickly in 1970? - Fishing ships began using new tools with which they could catch more fish. - There were fewer smaller fish than before. - There were more people catching big predators. - Their environment was being polluted by fishing ships.
(Answer)
Fishing ships began using new tools with which they could catch more fish.

The Dutch Health Council , in an overview of research from around the world , last year found no evidence radiation from mobile phones and TV towers was harmful . A four-year British survey released in January showed no link between regular . long-term use of cell phones and the most common type of tumor . However , researchers at the Swedish National Institute for Working Life said they looked at the mobile phone use of 905 people between the age of 20 and 80 who had been diagnosed with a malignant brain tumor and found a link " A total 80 of these 905 cases were so-called high users of mobile phones , that is they began early to use mobile and or wireless telephones and used them a lot , " the study said . " The study also shows that the rise in risk is noticeable for tumors on the sided of the head where the phone was said to be used , " it added . Kjell Mild , who led the study , said the figures meant that heavy users of mobile phones , for instance of who make mobile phone calls for 2 , 000 hours or more in their life , had a 240 percent increased risk for a malignant tumor on the side of the head the phone is used . " The way to the risk down is to use handsfree , " he told Reuters .
