Question: Input: Washington (CNN) -- The U.S. Food and Drug Administration announced Wednesday that laboratory tests on popular smoking devices known as electronic cigarettes have found they contain carcinogens and other toxic chemicals dangerous to humans. E-cigarettes are battery-operated and contain cartridges filled with nicotine and other chemicals. Known as "e-cigarettes," the devices are battery-operated and contain cartridges filled with nicotine and other chemicals, spiced with flavors such as chocolate, cola or bubble gum. While manufacturers tout e-cigarettes as a "healthy way" to smoke, federal health officials say the devices turn nicotine, which is highly addictive, and other chemicals into a vapor that is inhaled by the user. "The FDA is concerned about the safety of these products and how they are marketed to the public," said Dr. Margaret A. Hamburg, commissioner of the FDA. CNN contacted Florida-based Smoking Everywhere, one of the largest manufacturers of e-cigarettes, after the FDA announcement, and a spokeswoman said the company had no comment. Because e-cigarettes have not been submitted to the FDA for evaluation or approval, the agency had no way of knowing the levels of nicotine or the amounts or kinds of other chemicals that the various brands of these products deliver to the user. That is why the FDA began to test them. The FDA's Division of Pharmaceutical Analysis analyzed the ingredients in a small sample of cartridges from two leading brands of e-cigarettes. In releasing its information, the FDA did not identify the two companies, but said in one sample, diethylene glycol -- a chemical used in antifreeze that is toxic to humans -- was detected. Other samples detected carcinogens that are dangerous to those who smoke them, the FDA said. The FDA has been examining and seizing shipments of non-U.S.-made e-cigarettes at the U.S. border since summer 2008. To date, 50 shipments have been stopped. The products examined thus far meet the definition of a combination drug-device product under the Federal Food, Drug, and Cosmetic Act. "We know very little about these devices, said Dr. Jonathan Samet, director of the Institute for Global Health at the University of Southern California, "but to say they are healthy -- that's highly doubtful." 

Does the response "Cola,bubble gum" correctly answer the question "What are two chemicals that have been detected by the FDA that are of a concern?"?

 We drove about a great deal--the country at the back of Deauville, going away from the sea, is lovely--very like England--charming narrow roads with high banks and hedges on each side--big trees with spreading branches meeting overhead--stretches of green fields with cows grazing placidly and horses and colts gambolling about.  It is a great grazing and breeding country.  There are many haras (breeding stables) in the neighbourhood, and the big Norman posters are much in demand.  I have friends who never take their horses to the country.  They hire for the season a pair of strong Norman horses that go all day up and down hill at the same regular pace and who get over a vast amount of country.  We stopped once or twice when we were a large party, two or three carriages, and had tea at one of the numerous farmhouses that were scattered about.  Boiling water was a difficulty--milk, cider, good bread and butter, cheese we could always find--sometimes a galette, but a kettle and boiling water were entirely out of their habits.  They used to boil the water in a large black pot, and take it out with a big spoon.  However, it amused us, and the water really did boil.

The earliest signs of people on Jamaica are the remains of the Arawak, an AmerIndian society that originated on the north coast of South America. Arawak peoples migrated to various Caribbean islands, arriving in Jamaica by the beginning of the eighth century. They were peaceful and lived by "slash-and-burn" farming. For meat, they bred pigs and ate iguana, both native to the island. They were highly skilled in such manual activities as thatching and weaving. In fact, the hammock was an AmerIndian invention that remains with us today; it is an object which, more than any other, evokes an image of a warm sunny day on a tropical isle. The Arawak left a legacy of paintings in places such as Runaway Caves near Discovery Bay, and shards of pottery found at their settlements near Nueva Sevilla and Spanish Town have added a little to our knowledge about them. Over 200 Arawak sites have been identified, and it is said that when the Spanish arrived in Jamaica there were approximately 100,000 Arawak living on the island. They called Jamaica "Xaymaca" ("land of wood and water"). Columbus and the Arrival of Europeans Columbus first arrived in Jamaica on 5 May 1494 at Discovery Bay, where there is now a small park in his honor. He stayed for only a few days but returned in 1502, landing here when the ships of his fleet became unserviceable; he waited at St. Ann's Bay for help to arrive from Cuba. After the death of Columbus in 1505, Jamaica became the property of his son Diego, who dispatched Don Juan de Esquivel to the island as Governor. Esquivel arrived in 1510 and created a base called Nueva Sevilla near St. Ann's Bay, from which he hoped to colonize the rest of the island. The Spanish immediately began subjugating the Arawak population, many of whom died under the yoke of oppression and of diseases carried by the Europeans. A number of them committed suicide rather than live the life created for them by the Spanish. The site of Nueva Sevilla proved to be unhealthy and mosquito-ridden, and in 1534 the Spanish founded Villa de la Vega, today known as Spanish Town. Pig breeding was the main occupation of these early settlers, but they also planted sugar cane and other crops that required large numbers of laborers. The number of Arawak had already fallen dramatically, so the Spanish began to import slaves from Africa to work the land; the first Africans arrived in 1517.
