PROBLEM: 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.
Answer: many families were using lamps

SOLUTION: During the 18th and 19th century, _ .

PROBLEM: Article: The U.S. government may issue stronger regulations about the use of tobacco. Many governments and private buildings have "No Smoking" regulations. In airplanes, on trains and at cinemas, Golf courses are seriously thinking of keeping out smokers, so are schools, shopping malls and even football fields. So where do people go to fill their lungs with nicotine? The government is working on it. One suggestion is that the government set aside a piece of land somewhere in the United States where smokers could go when they want a cigarette. Yellow Stone Park has been in the list, but many people don't agree because they fear that second-hand smoking would make the bears there sick. The Mojave Desert in California is also being studied, and so are Las Vegas Casinos . The smokers were not too nervous about the government idea. They say they are not going to California just to light up. They have a right to smoke at home. To make life more pleasure for those who find it hard to give up smoking, the government is seriously thinking of getting somewhere for the smokers. The tobacco companies are fighting the idea like mad. They say nobody has proved that cigarettes are bad for you. They say as a matter of fact, the doctors have proved that a cigarette saved a person's life after that person was shot. Other places under consideration are: the cold areas in Alaska, the Rocky Mountain in Colorado and the Whitewater River in Arkansas.
Answer: are not so free

SOLUTION: Smokers in the U.S. _ to light a cigarette now.

PROBLEM: Article: DALLAS - A suburban Dallas woman accused of killing her two young children told a 911 operator that she first tried to poison them because they were autistic and she wanted "normal kids," then choked them with a wire until they stopped moving, according to the recorded call. Irving police on Wednesday released recordings of the 911 call after Saiqa Akhter was charged with capital murder in the death of her 5-year-old son, Zain Akhter and her 2-year-old daughter, Faryaal Akhter.
