Q: Article: The future of pinnipeds looks much brighter today than it once did. At one time, about 100 years ago, it seemed certain that many pinnipeds in the world would be destroyed by human hunters. Today, it appears that most species( ) of pinnipeds are out of danger. Hunting was not controlled during the 18th and 19th centuries, because little was known about the lives of pinnipeds. Whales and pinnipeds were hunted for the oil from their body fat. This oil was used in lamps before electric lights were invented. Millions of seals and other pinnipeds were used to provide oil for the lamps of the world. As a result, the numbers of many pinniped species fell rapidly. Several things happened that helped to save pinnipeds. First, species that were hunted to near extinction were left alone because their numbers were too low and the cost of hunting them went up greatly. At the same time, electric lights were invented and the market for seal oil became smaller. Finally, governments around the world made laws to protect pinnipeds. As a result of all these things, the numbers of most pinniped species have grown in recent years. With some species, such as Northern fur seals, there may be as many animals alive today as there were before all the hunting began. However, oil is still a danger to pinnipeds and all sea animals. But this time it's not because they are hunted for their oil. The oil that puts them in danger is from oil spills in the sea. The oil covers their fur and reduces their body temperatures. Oil also sticks to the foods they eat. This modern danger to pinnipeds and their environment is one we must work to prevent.

Q: Article: Who Owns the Moon? Within the next ten years, the U. S., China, Israel, and a crowd of private companies plan to set up camp on the moon. So if and when they plant a flag, does _ give them property rights? A NASA working group hosted a discussion this week to ask: Who owns the moon? The answer, of course, is no use. The Outer Space Treaty, the international signed by more than 100 countries, states that the moon and other celestial bodies are the province of all mankind. No doubt that would annoy all of the people throughout the ages, like monks from the Middle Ages, who have tried to claim the moon was theirs. But ownership is different from property rights. People who rent apartments, for example, don't own where they live, but they still hold rights. So with all of the upcoming missions to visit the moon and beyond, space industry thought leaders are seriously asking themselves how to deal with a potential land rush. " This is a very relevant discussion right now. We've got this wave of new lunar missions from around the world," said William Marshall, a scientist in the small-spacecraft office at NASA, but who spoke this week at an event hosted by NASA's Co Lab, a collaborative public-private working group. He was speaking from his personal interest and not on behalf of the agency. To be sure, the United States aims to send astronauts back to the moon by as early as 2015, in a mission that would include a long-term settlement. China and Israel, among others, are also working on lunar projects. And for the first time, several private groups are building spacecraft to land on the moon in an attempt to win millions of dollars in the Google Lunar X Prize. Some participants say that they plan to gain some property rights in the mission.
Answer: no one can answer the question " Who owns the moon?"

A: In the passage the writer seems to be worrying that _ .

Q: Article: For shopoholics, the post-Christmas period means only one thing ---- sales! Across the country, prices are reducing sharply on clothing, electronics and home furniture, but London is the place for serious shopping, and you can certainly pick up some amazing bargains. The sales start on Boxing Day -- 26th December, and continue for the month of January, but the keenest bargain hunters get there early to be first through the doors. In Oxford Street queues formed outside shops ahead of before-dawn openings for the start of their sales. At Brent Cross, in north London, more than 1,000 people were queuing at 3.30 am for the 'Next' clothing store's sale which began at 4 am. Some eager individuals even camped outside the shops to be first in the line. Consumers who _ were rewarded with discounts of as much as 80% as department stores joined the bargain sales. The shops are very crowded as the sales reached the boiling-point, with more than half a million people gathering on London's West End. Famous sales include the biggest, most popular shops such as Harrods, Selfridges, Liberty and John Lewis. Department stores are always a good bet -- you're likely to find everything you need under one roof, including much-needed food and drinks! It's a good time to stock up on cheap small tools, and there's no better time to invest in some designer clothes. Some people are taking their partners shopping with them, and buying their Christmas presents in the sale----a practical but unromantic way of making sure you get the gift you really want. For a less exciting but less stressful shopping experience, online sellers are also getting in on the act with January sales of their own. The most organized of all are those who are already doing their present shopping for next Christmas, in the January sales!
