[Q]: Article: Money spent on advertising is money spent as well as any I know of. It selves directly to bring about a rapid sale of goods at reasonable prices, so setting up a firm home market and so making it possible to provide for export at good prices. By drawing attention to new ideas it helps greatly to raise standards of living. By helping to increase demand it causes an increased need for labor, and is therefore a nice way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television program would need to be doubled, and travel by bus or subway would cost more. And perhaps most important of all, advertising provides a promise of reasonable value in the products and services you buy. Besides the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare promote a product that fails to live up to the promise of his advertisements. He might fool some people for a little while through misleading advertising. He will not do so for long, for the public has the good sense not to buy the poor article more than once. If you see an article frequently advertised, it is the proof I know that the article does what is promised for it, and that it has good value. Advertising does more for the good of the public than any other force I can think of. There is one more point I feel I ought to touch on. Recently I heard a well-known television person declare that he was against advertising because it persuades rather than informs. He was telling us the real difference. Of course advertising tries to persuade. If its message were nothing but information, that would be difficult to get more people to buy, for even a detail such as the choice of the color of a shirt is a bit persuasive-advertising would be so boring that no one would pay any attention. But perhaps that is what the well-known television person wants.

[Q]: Article: Bears and humans often meet in National Parks. Although campers and hikers are warned not to feed the bears, many people ignore these warnings and feed the beasts anyway. When bears are used to people's food, problems soon arise. Bears like to eat a large variety of things, both meat and vegetable. Without human assistance, bears live nicely on roots, twigs, leaves of trees, insects and small animals. With people around, the bears' tastes quickly expand to include sandwiches, hot dogs, hamburgers, and anything else they can temp humans into giving up. Bears often develop clever strategies for getting people to let go their food supplies. More often than not, an unsuspecting hiker has taken off his or her pack for a rest only to have a bear charge out of the woods, grab the pack and quickly disappear into the underbrush with it. Hanging the pack on a tree branch won't help. Bears have been known to climb up, jump off, and catch the pack on the way down. One mother bear stretched up with her baby on her shoulders to reach a pack stored on a pole. Many bears threaten people into giving up their supplies. Although a bear is unlikely to attack a person and would probably run away if screamed at, few people are willing to do so. Most people drop the pack and run the other way. This, of course, delights the bear. In some places, the Park Service installed some metal barrels with lids to help campers keep their supplies safe from bears. Although the bears were unable to open these containers, the effort was less than successful. Most campers, unable to tell the metal drums from rubbish cans, never used them for the intended purpose.
Answer: can cause problems
[A]: Feeding bears on people's food_.

[Q]: Article: Although the Samoan Natives have long claimed to be the indigenous people of their islands, holding firm to the belief that Samoans were birthed by special creation in Samoa, it has been theorized by many linguists, based on linguistic commonalities as well as archaeological findings, that migrants from Southeast Asia arrived in the Samoan Islands approximately 3500 years ago, settling in what has come to be known as "Polynesia" further to the east. Early contact with Europeans was established in the 18th century. Christianity was formally introduced with the arrival of missionaries in August 1830. During the early 20th century the Samoan Islands were divided by Germany, Great Britain and the USA. Tutuila and Aunu'u islands were claimed by the USA. The western islands became German Samoa. In 1914, New Zealand forces captured the islands from Germany, thus becoming Western Samoa. Western Samoa regained its independence on January 1, 1962. Samoans are notable in rugby. Despite its small population, the island of American Samoa produces disproportionately a large number of world-class American football players. Samoan Mosi Tatupu was a member of NFL team the New England Patriots. Samoan Troy Polamalu was a member of the NFL team the Pittsburgh Steelers until he retired after the 2014 football season. Traditional Samoan tattoo proves the strong ties many Samoans feel for their culture. Samoans have practiced the art of tattooing for over 2,000 years. To this day, a man's tattoo widely covers from mid-back, down the sides, to the knees. A woman's tattoo is not quite as wide or heavy. The geometric patterns are based on ancient designs, and often indicate rank and status. Here is the process of tattooing. The tattoo master dips his cutting tools into black ink made from burnt shells, and then punctures designs into the skin. The cutting tool consists of a short piece of bamboo or light wood with a piece of tortoiseshell bound at right angles at one end. A little bone comb is bound to the lower broad end of the tortoiseshell. The larger the comb, the greater the area on the skin is covered with fewer strokes. The process takes days, and is sometimes partially accomplished over longer periods, with recovery in between.
