Rivers flowing over gentle slopes move more slowly. They move much more slowly than a mountain stream. These slow moving streams create different types of features than mountain streams. Slow moving water erodes the sides of their channels more than the bottom. Also, large curves in the stream form. These curves are called meanders. Meanders are caused by erosion and deposition. Remember, faster moving water causes erosion more quickly. Slower moving water erodes material more slowly. If water is moving slowly enough, the sediment being carried may settle out. This settling out, or dropping off, of sediment is deposition. The curves are called meanders because they slowly wander over the land. As meanders erode from side to side, they create a floodplain. This is a broad, flat area on both sides of a river. Eventually, a meander may become cut off from the rest of the river. This forms an oxbow lake.

Question: "Do meanders cause oxbow lakes?"

- no

With a budget of $329 million, LSC provides civil legal assistance to low-income people in every county in America, Kleiman said. NLAP was created in 1968. A decade later, the agency used a $50,000 LSC grant to buy a building at 438 King St. in Charleston and $33,000 to buy a building at 201 King St. in Georgetown, according to Erlenborn's letter to Kaynard. In 1980, NLAP used $63,000 in LSC funds to buy property at 607 Main St. in Conway, the letter said. On Nov. 14, 2001, NLAP transferred title of the King Street building in Charleston to the Charleston County Bar Association, according to county property records. The local bar paid $5 for the building, which sits between a redeveloped office building and an antique shop. The local bar said it would maintain the building for "legal services to indigent residents of Charleston County and coastal South Carolina," the records said. The King Street building appears to be vacant. Notices at the entrance direct visitors to the equal justice center on West Montague Avenue in North Charleston. E. Douglas Pratt-Thomas, president of the local bar, was not available for comment. Charleston County has not appraised the King Street property because it is tax-exempt. But Randall Goldman, managing partner of Patrick Properties, which owns buildings from 440 to 456 King St., said he estimates 438 King St. would sell for between $700,000 and $900,000. "That building, which was purchased solely with federal legal aid dollars, should be used to provide legal services for poor people in South Carolina," Kleiman said. LSC wants the title to go to the equal justice center in Charleston or "we want 100 percent of the proceeds from the sale of the building to stay in Charleston. We are not contemplating taking that money out of South Carolina," he said. Kleiman said if the neighborhood legal program in Charleston "had honored their obligation, this would not be an issue."

Question: "The local bar in Charleston County maintained which building of the NLAP in exchange for "legal services" to certain residences?"

Problem: When he was at Oxford he had been well known for concealing under a slightly rowdy exterior the highest spirits of any of the undergraduates. He was looked upon as the most fascinating of _farceurs_. It seems that he had distinguished himself there less for writing Greek verse, though he was good at it, than for the wonderful variety of fireworks that he persistently used to let off under the dean's window. It was this fancy of his that led, first, to his popularity, and afterwards to the unfortunate episode of his being sent down; soon after which he had married privately, chiefly in order to send his parents an announcement of his wedding in _The Morning Post_, as a surprise. Some people had come in after dinner--for there was going to be a little _sauterie intime_, as Mrs Mitchell called it, speaking in an accent of her own, so appalling that, as Vincy observed, it made it sound quite improper. Edith watched, intensely amused, as she saw that there were really one or two people present who, never having seen Mitchell before, naturally did not recognise him now, so that the disguise was considered a triumph. There was something truly agreeable in the deference he was showing to a peculiarly yellow lady in red, adorned with ugly real lace, and beautiful false hair. She was obviously delighted with the Russian prince.

Question: "What caused the individual in Sentence 4 to be "sent down"?"

Answer: "Lighting fireworks under Dean's window"

OPTIONS:
- no
- yes
Answer: yes

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."
