TASK DEFINITION: Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.
PROBLEM: Ponds are small bodies of fresh water that usually have no outlet; ponds are often are fed by underground springs. Like lakes, ponds are bordered by hills or low rises so the water is blocked from flowing directly downhill. Lakes are larger bodies of water. Lakes are usually fresh water, although the Great Salt Lake in Utah is just one exception. Water usually drains out of a lake through a river or a stream and all lakes lose water to evaporation. Lakes form in a variety of different ways: in depressions carved by glaciers, in calderas (Figure 1.1), and along tectonic faults, to name a few. Subglacial lakes are even found below a frozen ice cap. As a result of geologic history and the arrangement of land masses, most lakes are in the Northern Hemisphere. In fact, more than 60% of all the worlds lakes are in Canada most of these lakes were formed by the glaciers that covered most of Canada in the last Ice Age (Figure 1.2). Lakes are not permanent features of a landscape. Some come and go with the seasons, as water levels rise and fall. Over a longer time, lakes disappear when they fill with sediments, if the springs or streams that fill them diminish, (a) Crater Lake in Oregon is in a volcanic caldera. Lakes can also form in volcanic craters and impact craters. (b) The Great Lakes fill depressions eroded as glaciers scraped rock out from the landscape. (c) Lake Baikal, ice coated in winter in this image, formed as water filled up a tectonic faults. Lakes near Yellowknife were carved by glaciers during the last Ice Age. or if their outlets grow because of erosion. When the climate of an area changes, lakes can either expand or shrink (Figure 1.3). Lakes may disappear if precipitation significantly diminishes. Large lakes have tidal systems and currents, and can even affect weather patterns. The Great Lakes in the United States contain 22% of the worlds fresh surface water (Figure 1.1). The largest them, Lake Superior, has a tide that rises and falls several centimeters each day. The Great Lakes are large enough to alter the weather system in Northeastern United States by the lake effect, which is an increase in snow downwind of the relatively warm lakes. The Great Lakes are home to countless species of fish and wildlife. Many lakes are not natural, but are human-made. People dam a stream in a suitable spot and then let the water back up behind it, creating a lake. These lakes are called "reservoirs." Click image to the left or use the URL below. URL:

SOLUTION: which of these is not full of fresh water?

PROBLEM: You have been badly injured in a car accident. It is necessary to give you a blood transfusion because you lost a great deal of blood in the accident. However, special care must be taken in selecting new blood for you. If the blood is too different from your own, the transfusion could kill you. There are four basic types of blood; A, B, AB, and O. A simple test can make sure of a person's blood type. Everybody is born with one of these four types of blood. Blood type, like hair color1 and height, is received from parents. The four groups must be transfused carefully. A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. O can give to any other group; therefore, it is often called the universal donor . For the opposite reason, AB is sometimes called the universal recipient . However, because so many reactions can happen in transfusions , patients usually receive only salt of plasma (liquid part of blood) until their blood can be matched as exactly as possible in the blood bank of a hospital. In this way, it is possible to prevent the transfusion from any bad reactions.

SOLUTION: People with type A blood can receive type     .

(March 2010) (Learn how and when to remove this template message) On March 17, 994 A.D., The Leprechaun is a thousand years old. Since that is his birthday, he can choose any woman to be his bride. He picks a young girl of the O'Day family. The Leprechaun describes the girl he has chosen to O'Day, but when O'Day sees that the girl is in fact his daughter, he intervenes with "God bless you, my child" therefore denying the Leprechaun his bride, as the creature can marry any girl who sneezes three times, provided no one says "God bless you." The Leprechaun captures, tortures and tells O'Day that he will marry his descendant in a thousand years time on St Patrick's Day, before he kills O'Day, whose corpse is then discovered by his daughter. One thousand years later, St Patrick's Day 1994, in modern-day Los Angeles, the Leprechaun has found a petulant sixteen-year-old girl named Bridget Callum, a descendant of the O'Day bloodline, who has got into a fight with her boyfriend, Cody Ingalls. Cody, whose legal guardian is his uncle, Morty, frequently has to break their dates in order to support Morty, an alcoholic scam artist. The Leprechaun steals some whiskey and a gold tooth from a homeless man and a gold ring off the finger of Tim Streer, a talent agent, who believes that the little man is some kind of performer. After all of this, he follows Bridget to her house, where a boy named Ian attempts to persuade her into letting him in; she refuses with a swift elbow to his ribs. The Leprechaun then creates an illusion that fools Ian into believing that Bridget is asking him to kiss her big breasts, while in actuality, they are a pair of lawnmower blades that start up after Ian shoves his face into them. Shortly afterwards, Cody knocks on the door and apologizes, offering flowers, which causes Bridget to sneeze all over his shirt. The third time she sneezes, Cody begins to say "God bless you," but is unable to complete the blessing when the Leprechaun attempts to strangle him with a telephone cord. After a struggle, the Leprechaun grabs Bridget and disappears, losing one of his gold coins, which Cody soon finds. The police soon arrive, find Bridget missing, Ian dead, and a note from Cody at the scene, leading them to get an arrest warrant out for him. Cody returns to Morty's house and tells him what happened; Morty says he's crazy until the Leprechaun breaks into the house and they barely escape. Morty and Cody then go to a bar, which is filled with little people dressed as leprechauns, celebrating St. Patrick's Day. While there, Cody is given a piece of chocolate in a gold wrapper by one of the bar's patrons (Tony Cox). The Leprechaun appears and Morty challenges him to a drinking contest in honor of his wedding. While the Leprechaun downs whiskey, Morty is actually drinking soda and water. The Leprechaun eventually becomes extremely drunk, so much to the point he can barely speak properly or use his magic. He distracts Morty and Cody by turning on a jukebox with his powers, leading him to bash Morty in the head with a bottle to get away. He goes to a coffee shop, where he sobers up, and takes the time to murder a waiter (Michael McDonald) who was making jokes about his size and speech. Upon being asked for payment for the coffee, the leprechaun thinks the waiter wants to take his gold and kills him. Meanwhile, Cody and Morty break into the go-kart racetrack that Ian worked at since the office contains a huge safe on wheels made of wrought iron, the only thing that can harm the Leprechaun. Cody traps the Leprechaun inside, but Morty takes advantage of the opportunity to claim three wishes and locks Cody in a store room. His first is for the Leprechaun's pot of

Who does Cody find  that Bridgette actually is?
