Article: When did you last see a polar bear ? On a trip to a zoo, perhaps? If you had attended a winter activity in New York a few years ago, you would have seen a whole polar bear club. These "Polar Bears" are people who meet frequently in the winter to swim in freezing cold water. That day, the air temperature was 3degC, and the water temperature was a bit higher. The members of the Polar Bears Club at Coney Island, New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group; this is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February. Doctors do not agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body's temperature drops so low that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and water temperature is much greater in summer than in winter. The Polar Bears themselves are satisfied with the benefits(or advantages)of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and should not try cold-water swimming. The main benefits(or advantages)of cold-water swimming are probably mental. The Polar Bears love to swim year-round; they find it fun and relaxing. As one 70-old woman says, When I go into the water , I pour my troubles into the ocean and let them float away. Question: Doctors _ . Yes or no, is the answer "have different ideas about the medical effects of cold-water swimming["?

Article: You've bought what you need. The grocery cashier asks, "Will that be paper or plastic? You reply "Plastic, please." This seems like a simple question and there are plenty of reasons we choose plastic: easier to carry, lighter than paper bags, possibly less damaging to the environment, less expensive to the shop owners, able to be used as trash bag, and so on. There are different opinions on plastic and paper. Now let's follow the travels of 3 plastic bags. It begins at the grocery store with the customer's choice. Plastic Bag 1: As the waste engineer come by and pick up the trash, the first plastic bag falls out. It sits on a small street for a couple of hours until a car comes along and takes it down to the road. Then a gust of wind blows it across the road, then another car, then another gust of wind finally makes its way to the beach. Water fills the plastic bag and makes it look like a jellyfish. A seal swims by, thinking it looks very interesting, and swallowed it. The plastic bag may stay in the seal's stomach for months, maybe years. You see, our lovely animals have been living thousands of years in a world where everything can be eaten. Plastic Bag 2: This bag does make its way to landfill . Before they have a chance to cover up the thousands of pounds of daily waste, a strong wind comes up and blows these plastic bags out of the landfill. Once the wind stops, workers will be sent to collect thousands of bags around. But they can't possibly get them all. So our little bag continues his adventure getting caught in trees, eaten by birds or making its way to our lakes or rivers. Plastic Bag 3: The last bag also blows away but is caught in a landfill where it sits for many years, as all the trash is wrapped in a big plastic bag, making natural degradation impossible. Although workers do much work to make sure water and air system won't be polluted, some do. Guess what, plastic bags are made from petrol, a harmful waste material, which in one way or another makes its way to the environment. Another... Question: What is the overall tone of this passage? Yes or no, is the answer "Ironical"?

Article: Robert Spring, a 19th century forger , was as good at his profession that he was able to make his living for 15 years by selling false signatures of famous Americans. Spring was born in England in 1813 and arrived in Philadelphia in 1858 to open a bookstore. At first he make some money by selling his small but genuine of early U.S. autographs . Discovering his ability at copying handwriting, he began imitating signatures of George Washington and Ban Franklin and writing them on the title pages of old books. To make less the chance of detection , he sent his forgeries to England and Canada for sale and circulation . Forgers have a hard time selling their products. A forger can't approach a respectable buyer but must deal with people who don't have much knowledge in the field. Forgers have many ways to make their work look real. For example, they buy old books to use the aged paper of the title page, and they can treat paper and ink with chemicals. In Spring's time, right after the Civil War, Britain was still fond of the Southern states, so Spring invented a respectable maiden lady known as Miss Fanny Jackson, the only daughter of General "Stonewall" Jackson. For several years Miss Fanny's economic problems forced her to sell a great number of letters and manuscripts belonging to her famous father. Spring had to work very hard to satisfy the demand. All this activity did not prevent Spring from dying in poverty, leaving sharp-eye experts the difficult task of separating this forgeries from the originals. Question: After the Civil War, there was a great demand in Britain for _ . Yes or no, is the answer "Southern manuscripts and letters"?
