Problem: Water flowing over Earths surface or underground causes erosion and deposition. Water flowing over a steeper slope moves faster and causes more erosion. How water transports particles depends on their size. When water slows down, it starts depositing sediment. This process starts with the largest particles first. Runoff erodes the land after a heavy rain. It picks up sediment. Runoff carries most of the sediment to bodies of water. Mountain streams erode narrow, V-shaped valleys and waterfalls. Erosion and deposition by slow-flowing rivers create broad floodplains and meanders. Deposition by streams and rivers may form alluvial fans and deltas. Floodwaters may deposit natural levees. Erosion and deposition by groundwater can form caves and sinkholes. Stalactites and stalagmites are mineral deposits. They build up in caves as water continues to drip.

Question: "Which particles are deposited first when water flowing over Earth's surface begins to slow down?"

Answer: "Sediment"

Question:
Right after the Pentagon was hit, NEADS learned of another possible hijacked aircraft. It was an aircraft that in fact had not been hijacked at all. After the second World Trade Center crash, Boston Center managers recognized that both aircraft were transcontinental 767 jetliners that had departed Logan Airport. Remembering the "we have some planes" remark, Boston Center guessed that Delta 1989 might also be hijacked. Boston Center called NEADS at 9:41 and identified Delta 1989, a 767 jet that had left Logan Airport for Las Vegas, as a possible hijack. NEADS warned the FAA's Cleveland Center to watch Delta 1989. The Command Center and FAA headquarters watched it too. During the course of the morning, there were multiple erroneous reports of hijacked aircraft. The report of American 11 heading south was the first; Delta 1989 was the second. NEADS never lost track of Delta 1989, and even ordered fighter aircraft from Ohio and Michigan to intercept it. The flight never turned off its transponder. NEADS soon learned that the aircraft was not hijacked, and tracked Delta 1989 as it reversed course over Toledo, headed east, and landed in Cleveland. But another aircraft was heading toward Washington, an aircraft about which NORAD had heard nothing: United 93. United Airlines Flight 93 FAA Awareness. At 9:27, after having been in the air for 45 minutes, United 93 acknowledged a transmission from the Cleveland Center controller. This was the last normal contact the FAA had with the flight. Less than a minute later, the Cleveland controller and the pilots of aircraft in the vicinity heard "a radio transmission of unintelligible sounds of possible screaming or a struggle from an unknown origin." The controller responded, seconds later: "Somebody call Cleveland?"This was followed by a second radio transmission, with sounds of screaming. After reading the above, is "Just before 9:30" the correct answer to the question "At what time was the FAA's last normal communication with United Airlines flight 93?"? OPTIONS:
- no
- yes

Answer:
yes

Input: Oscar-winning actress Joan Fontaine died Sunday, her longtime friend Noel Beutel said Monday. She was 96. Fontaine died "very peacefully" in her sleep of natural causes, Beutel said. She was in her Carmel, California, home. She is survived by her older sister, actress Olivia de Havilland -- with whom she had not spoken for decades. Fontaine was born Joan de Beauvoir de Havilland in 1916 in Tokyo, Japan, where her British father was a patent lawyer and teacher. She and her sister moved to Saratoga, California, with their mother in 1919 when her parents separated. Fontaine was a teenager when she began her acting career as Joan Burfield in the 1935 film "No More Ladies." She later adopted the stage name Fontaine -- the name of her mother's second husband. She wrote in her 1978 autobiography, "No Bed of Roses," that her mother, who was an actress, began encouraging the rivalry with her older sister at an early age. The feud extended to their careers when both sisters were nominated for best actress Oscars in 1942. Fontaine, who was nominated for Alfred Hitchcock's "Suspicion," beat her sister Olivia de Havilland, who was nominated for "Hold Back the Dawn." De Havilland won the first of her two Oscars in 1947 when she was given the best actress award for "To Each His Own." De Havilland and Fontaine remain the only sisters who have best-actress Academy Awards. The long-standing feud with de Havilland was at such a peak during one Oscar winners' reunion in 1979 that they had to be seated on opposite ends of the stage. "I was shocked and saddened to learn of the passing of my sister, Joan Fontaine ... and I appreciate the many kind expressions of sympathy that we have received," a statement released by Olivia de Havilland to CNN said.
"How old was Joan when she wrote an autobiography?" is "Fourteen"?

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."
"Who are two people in the passage that question the safety of e-cigarettes?" is "Spokeswoman , commissioner of the FDA"?

- no

no
