A flood occurs when a river overflows its banks. This might happen because of heavy rains. Floodplains In very flat regions, flood water may spread out on the surface of the land. It then slows down and drops its sediment. If a river floods often, a floodplain develops. A floodplain is an area where a thick layer of rich soil is left behind as the floodwater recedes. Thats why floodplains are usually good places for growing plants. They are very flat areas and they have very rich soils. The Nile River valley is a great example of a floodplain. Each year, the Nile River rises over its banks. This floodwater carries a lot of sediment. This sediment has been eroded off areas of land from upstream. This sediment is dropped as the water slows down after spreading across the land. What is left behind is a very rich soil. Thats why crops can be raised in the middle of a sandy desert. Natural Levees A flooding river often forms natural levees along its banks. A levee is a raised strip of sediments deposited close to the waters edge.

I had drunk too much, I confess, though we all had. Somehow, Tasha and I began to argue the worth of Solevgrad jazz, as inconsequential a topic as I can imagine. She had studied it in school, so she thought herself as an expert. I once had a neighbor who played it constantly, loudly, and badly, so I thought I knew it better. Malaquez tried to mediate, but I saw him as siding with Tasha. So, I think, did she. The subject shifted from music to Tasha's obsession with fame, undoubtedly by a leap that I made. She had no choice but to follow. (I do not remember any of this well, just now, nor do I care to. Those who are truly curious may look at the last act of "Captured Moments.") I remember suggesting, with characteristic tact, that she add Emil to her small list of major accomplishments. Malaquez glanced away, embarrassed. Tasha looked at me as if to say, "I will." She said, "I feel sorry for you, Nardo. I'll see Emil home." "Yes," I said, "Do that," and did not care what she did, or why. Emil asked, "You're all right?" I muttered something he must have interpreted as assent. They both walked up to Emil's home while I watched the scarlet moonlight ripple on distant waves. Disgusted with Tasha but more disgusted with myself, I finally realized she would not return that night and went into The Sleeping Flamingo to drink myself to sleep. She had not come home when I woke in mid-morning.

Question: "Why does Nardo struggle to remember these events?"

OPTIONS:
- no
- yes

Answer: "He has bad memory"

Response: no

(CNN) -- The photographer who took images of former Pakistani Prime Minister Benazir Bhutto moments before her assassination Thursday told CNN he was "surprised" to see her rise through the sunroof of her vehicle to wave to supporters after delivering her speech. Getty Images photographer John Moore captured Benazir Bhutto waving, moments before he heard gunshots. "I ran up, got as close as I got, made a few pictures of her waving to the crowd," Getty Images senior staff photographer John Moore told CNN's online streaming news service, CNN.com Live, in a phone interview Thursday from Islamabad, Pakistan. "And then suddenly, there were a few gunshots that rang out, and she went down, she went down through the sunroof," he said. "And just at that moment I raised my camera up and the blast happened. ... And then, of course, there was chaos." Watch Moore describe Bhutto's final moments " Moore said he was about 20 yards away from Bhutto's vehicle when he took his photographs. Bhutto was rushed to Rawalpindi General Hospital, where she was pronounced dead. Moore said he had been following Bhutto's story since her return to Pakistan in October. He was present October 19 when a terror attack targeting her motorcade in Karachi killed 136 people. In the aftermath of that attack, "The rallies had been very small," because of high security, Moore said. However, the Rawalpindi rally was announced beforehand, he observed. "Whoever planned this attack -- they had time on their hands to plan everything properly, and you saw the results today," he said. Between 5,000 and 8,000 were at the Rawalpindi rally, which was held at a parkground, he said. "We [the news media] all expected it to be filled ... but there were less people there than most of us expected to see," he said. "When I talked with a number of people, they said that people were just afraid to come out, for the simple reason that they all remembered what happened in Karachi." Moore said he himself expected there could be another attack following the Karachi massacre. He said he stayed away from gates at the Rawalpindi parkground, where police were searching people, because he suspected that's where a bomb would go off.

Question: "Why were there less people than the news reporters expected to see?"

These incoherent words threw the first glimpse of light on the meaning of her distress and penitence. I doubt if the best woman in Christendom would so reproach and abase herself, if convicted of even a worse sin than the secret use of those stimulants for which the "charny" is a Martial equivalent. No Martialist would dream of poisoning his blood and besotting his brain with alcohol in any form. But their opiates affect a race addicted to physical repose, to sensuous enjoyment rather than to sensual excitement, and to lucid intellectual contemplation, with a sense of serene delight as supremely delicious to their temperament as the dreamy illusions of haschisch to the Turk, the fierce frenzy of bhang to the Malay, or the wild excitement of brandy or Geneva to the races of Northern Europe. But as with the luxury of intoxication in Europe, so in Mars indulgence in these drugs, freely permitted to the one sex, is strictly forbidden by opinion and domestic rule to the other. A lady discovered in the use of "charny" is as deeply disgraced as an European matron detected in the secret enjoyment of spirits and cigars; and her lord and master takes care to render her sufficiently conscious of her fault.

Question: "The Secret use of what kind of stimulants was a Martial equivalent for women?"

OPTIONS:
- no
- yes

Answer: "Alcohol"

Response:
yes
