Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

Example Input: Context: When once-wealthy string magnate Rudolf Smuntz (William Hickey) dies, he leaves his outdated string factory and a run-down mansion to his two sons, Lars (Lee Evans) and Ernie (Nathan Lane). When Lars refuses a proposal by representatives from the large Zeppco conglomerate to purchase their string factory, his wife April (Vicki Lewis) throws him out. Meanwhile, Ernie serves Mayor McKrinkle (Cliff Emmich) at his restaurant in anticipation of becoming a famous chef for serving such a high-profile guest. However, the mayor is poisoned by a cockroach (which came from Rudolf's old box of Cuban cigars that Ernie took for himself) and suffers two heart attacks, with the latter fatal. As a result, Ernie's restaurant is closed down by the Board of Health. Finding blueprints of the mansion that they decide to live in, Ernie and Lars discover that it is a lost masterpiece designed by famous architect Charles Lyle LaRue. LaRue collector Alexander Falko (Maury Chaykin) makes a proposal, but Ernie refuses under the belief they can make a larger profit by restoration and auction. However, the brothers have already realized that the house has one stubborn occupant: a tiny and treacherous mouse. When a single mousetrap proved to be useless against the mouse, Ernie and Lars cover the entire kitchen floor with a number of mousetraps, but end up trapped in the kitchen when the door is locked. The mouse slips through the maze of traps with ease and drops a cherry, setting off the mousetraps in a dominoes effect. The brothers attempt to kill the mouse with a vacuum cleaner, but are covered with sewage. The brothers purchase a monstrous cat named "Catzilla" to deal with the mouse. Catzilla chases the mouse throughout the house while destroying everything, but gets tricked onto the house's dumbwaiter as the mouse sends him on a one-way trip down to his demise. They then hire an eccentric exterminator named Caesar (Christopher Walken) to handle the mouse, though he is severely injured and hospitalized. Later, Ernie chases the mouse up a chimney and gets stuck, and Lars attempts to light a match while the mouse starts a gas leak, creating an explosion that blasts Ernie out of the chimney and into the lake. Ernie takes a shotgun to fire at the mouse, accidentally shooting a compressed can of pesticide that Caesar left behind, making a large hole. After the two recover, Lars throws an orange at Ernie, but accidentally knocks the mouse unconscious. Unable to finish him off, they instead seal the mouse in a box and mail him to Fidel Castro in Cuba. The brothers reconcile again and finish renovating the house. When the night of the auction arrives, Lars discovers the mouse's box in the snow returned due to insufficient postage and with a big hole gnawed through it. Lars and Ernie panic upon seeing the mouse return, but attempt to maintain their composure as the auction continues. The mouse also devours Rudolf's "lucky string," which he gave to the brothers before his death, making their vendetta even more personal. The brothers desperately attempt to flush out the mouse by feeding a hose into the wall. As the auction reaches a record $25 million bid, the house rapidly floods through the walls and the floors, causing everyone to be washed out of the house as it promptly collapses. The brothers' only consolation is the fact that the mouse must finally be dead as their father's "lucky string" is found in the wreckage. With nowhere else to go, the brothers return to the factory and fall asleep, with only a single chunk of cheese for food. Having followed them, the mouse restarts and feeds the cheese into the machinery inventing the world's first string cheese, which inspires Ernie and Lars. Ernie and Lars end their war with the mouse and have successfully rebuilt the factory as a novelty string cheese company. Lars has begun a relationship with one of the two sisters Hilde, and Ernie puts his culinary skill to work in developing new cheese flavors with the mouse as his personal taste-tester. 
 Question: Who does Ernie accidentally kill?
Example Output: the mayor

Example Input: Context: Assume that a school bus, like the one in Figure 12.2, passes by as you stand on the sidewalk. Its obvious to you that the bus is moving. It is moving relative to you and the trees across the street. But what about to the children inside the bus? They arent moving relative to each other. If they look only at the other children sitting near them, they will not appear to be moving. They may only be able to tell that the bus is moving by looking out the window and seeing you and the trees whizzing by. This example shows that how we perceive motion depends on our frame of reference. Frame of reference refers to something that is not moving with respect to an observer that can be used to detect motion. For the children on the bus, if they use other children riding the bus as their frame of reference, they do not appear to be moving. But if they use objects outside the bus as their frame of reference, they can tell they are moving. What is your frame of reference if you are standing on the sidewalk and see the bus go by? How can you tell the bus is moving? The video at the URL below illustrates other examples of how frame of reference is related to motion. MEDIA Click image to the left or use the URL below. URL: Did you ever go to a track meet like the one pictured in Figure 12.3? Running events in track include 100-meter sprints and 2000-meter races. Races are named for their distance. Distance is the length of the route between two points. The length of the route in a race is the distance between the starting and finishing lines. In a 100-meter sprint, for example, the distance is 100 meters. The SI unit for distance is the meter (1 m = 3.28 ft). Short distances may be measured in centimeters (1 cm = 0.01 m). Long distances may be measured in kilometers (1 km = 1000 m). For example, you might measure the distance a frogs tongue moves in centimeters and the distance a cheetah moves in kilometers. Maps can often be used to measure distance. Look at the map in Figure 12.4. Find Mias house and the school. You can use the map key to directly measure the distance between these two points. The distance is 2 kilometers. Measure it yourself to see if you agree. Things dont always move in straight lines like the route from Mias house to the school. Sometimes they change direction as they move. For example, the route from Mias house to the post office changes from west to north at the school (see Figure 12.4). To find the total distance of a route that changes direction, you must add up the distances traveled in each direction. From Mias house to the school, for example, the distance is 2 kilometers. From the school to the post office, the distance is 1 kilometer. Therefore, the total distance from Mias house to the post office is 3 kilometers. You Try It! Problem: What is the distance from the post office to the park in Figure 12.4? Direction is just as important as distance in describing motion. For example, if Mia told a friend how to reach the post office from her house, she couldnt just say, "go 3 kilometers." The friend might end up at the park instead of the post office. Mia would have to be more specific. She could say, "go west for 2 kilometers and then go north for 1 kilometer." When both distance and direction are considered, motion is a vector. A vector is a quantity that includes both size and direction. A vector is represented by an arrow. The length of the arrow represents distance. The way the arrow points shows direction. The red arrows in Figure 12.4 are vectors for Mias route to the school and post office.

Example Input: Context: At 60, rue des Archives, this Hotel de Guenegaud was built between 1651 and 1655 for Jean-Francois de Guenegaud des Brosses, secretaire du Roi, maitre des Comptes and conseiller d'Etat, by Francois Mansart (the only hotel particulier this architect built to have fully survived).
