Input: Consider Input: Context: The muscular system consists of all the muscles in the body. This is the body system that allows us to move. You also depend on many muscles to keep you alive. Your heart, which is mostly muscle, pumps blood around your body. Each muscle in the body is made up of cells called muscle fibers. Muscle fibers are long, thin cells that can do something that other cells cannot dothey are able to get shorter. Shortening of muscle fibers is called contraction. Muscle fibers can contract because they are made of proteins, called actin and myosin, that form long filaments (or fibers). When muscles contract, these protein filaments slide or glide past one another, shortening the length of the cell. When your muscles relax, the length extends back to the previous position. Nearly all movement in the body is the result of muscle contraction. You can control some muscle movements. However, certain muscle movements happen without you thinking about them. Muscles that are under your conscious control are called voluntary muscles. Muscles that are not under your conscious control are called involuntary muscles. Muscle tissue is one of the four types of tissue found in animals. There are three different types of muscle in the body ( Figure 1.1): 1. Skeletal muscle is made up of voluntary muscles, usually attached to the skeleton. Skeletal muscles move the body. They can also contract involuntarily by reflexes. For example, you can choose to move your arm, but your arm would move automatically if you were to burn your finger on a stove top. This voluntary contraction begins with a thought process. A signal from your brain tells your muscles to contract or relax. Quickly contract and relax the muscles in your fingers a few times. Think about how quickly these signals must travel throughout your body to make this happen. 2. Smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. These muscles push materials like food or blood through organs. Unlike skeletal muscle, smooth muscle can never be under your control. 3. Cardiac muscle is also an involuntary muscle, found only in the heart. The cardiac muscle fibers all contract together, generating enough force to push blood throughout the body. What would happen if this muscle was under conscious or voluntary control? There are three types of muscles in the body: cardiac, skeletal, and smooth. 
 Question: what muscle pushes food through your intestines?

Output: smooth muscle


Input: Consider Input: Context: The movie starts off with archive black-and-white footage of the Nazi's atrocities on the Jews across Europe. The focus shifts to West Belarus, where Nazi SS soldiers, under the command of Bernicki, the Belarussian Police Captain, are busy "sanitizing" a village, killing half the people and abducting the rest. Zus Bielski (Liev Schreiber) and his brother, Asael (Jamie Bell), watch helplessly from the forest. Once the Germans have left, they run to the village and are devastated to find their father dead. They go to their house and find their youngest brother, Aron (George MacKay), cowering under the floorboards in the closet. They take him with them to the forest.In the Lipiczanska Forest, Zus tells a weeping Asael to get a hold of himself. As they sleep, their eldest brother, Tuvia Bielski (Daniel Craig), walks up to them and wakes them up. He first admonishes Asael for not being alert, then embraces him and Aron emotionally. Zus and Tuvia have a rather curt reunion. As they walk into the forest, Zus tells Tuvia that his wife and child are hiding in a village. At night, they discuss their options. The police are after them, however they are safe in the woods. They talk about Bernicki. A friend, Koscik has a gun which they can borrow. Next morning, Aron stumbles across some other Jewish refugees in the forest. He brings them back to his brothers. One of them is a young child, mortally wounded. Unfortunately, they can't save her. As her parents grieve, Zus tells Tuvia that they can't support these people. Tuvia says he'll ask Koscik for food and his pistol.In the nearby village, Konstanty 'Koscik' Kozlowski, their friend and a secret Jew-sympathizer, lets Tuvia inside and gives him food, drink and his pistol, with only 4 bullets. Seeing a police car coming towards the house, Koscik hides Tuvia in the barn, along with some other Jews. It's Bernicki and his sons, who Koscik welcomes warmly. Bernicki talks about his Jew-hunting exploits. Bernicki talks about having killed the Bielskis' father and is now after the sons. He tells Koscik to keep his eyes open and leaves. After they're gone, Koscik gives Tuvia food and drink and asks him to take the Jews from his barn. Tuvia confirms that Bernicki and his sons were responsible for his parent's deaths. He then takes the other Jews and goes into the forest.As they walk into the forest, one of the Jews, an elderly man named Shamon Haretz, Tuvia's old school-teacher, talks to him about his experiences. Tuvia brushes him off. At the campsite, the food is being passed around, with each person taking a small morsel so the others can have some. Zus is upset that Tuvia brought more mouths to feed. Tuvia tells him that it was Bernicki who killed their parents. That night, he goes to Bernicki's house, where he is having dinner with his wife and two sons. Tuvia bursts inside and holds them at gunpoint. He asks them if he knows who he is and why he's there. Terrified, Bernicki says he did as ordered. Tuvia orders him to his knees. Bernicki's sons jump up to their father's aid, but Tuvia shoots them dead. He then shoots Bernicki dead. Bernicki's hysterical wife pleads with Tuvia to kill her as well. Leaving her alive and grief-stricken, he leaves.The next morning, Tuvia tells Zus he killed Bernicki and his sons. They decide to move deeper into the woods. Tuvia brings over more Jews, much to Zus' displeasure. One of them is Isaac Malbin (Mark Feuerstein). The refugees start building makeshift houses in the woods. After almost hitting Zus with a log, Isaac confesses that he's an intellectual, not a carpenter. A refugee introduces Tuvia to his "forest wife". Tuvia congratulates them, a bit unsurely. Just then, two men burst into the scene, one of them holding a rifle, while 
 Question: Where did the brothers flee?

Output: into another part of the woods.


Input: Consider Input: Context: Brink (Sir Cedric Hardwicke) has recently taken Pud's (Bobs Watson) parents in an auto wreck. Brink later comes for Gramps (Lionel Barrymore). Believing Brink to be an ordinary stranger, the crotchety old Gramps orders Mr. Brink off the property. Pud comes out of the house and asks who the stranger was. Gramps is surprised and relieved that someone else could see the stranger; he was not merely a dream or apparition. Pud tells Gramps that when he does a good deed, he will be able to make a wish. Because his apples are constantly being stolen, Gramps wishes that anyone who climbs up his apple tree will have to stay there until he permits them to climb down. Pud inadvertently tests the wish when he has trouble coming down from the tree himself, becoming free only when Gramps says he can. Pud's busybody Aunt Demetria (Eily Malyon) has designs on Pud and the money left him by his parents. Gramps spends much time fending off her efforts to adopt the boy. Brink takes Granny Nellie (Beulah Bondi) in a peaceful death just after she finishes a bit of knitting. When Mr. Brink returns again for Gramps, the old man finally realizes who his visitor is. Determined not to leave Pud to Demetria, Gramps tricks Mr. Brink into climbing the apple tree. While stuck in the tree, he cannot take Gramps or anyone else. The only way anyone or anything can die is if they touch Mr. Brink or the apple tree. Demetria plots to have Gramps committed to a psychiatric hospital when he claims that Death is trapped in his apple tree. Gramps proves his story first by proving that his doctor, Dr. Evans (Henry Travers), can not even kill a fly they have captured. He offers further proof of his power by shooting Mr. Grimes (Nat Pendleton), the orderly who has come to take him to the asylum; Grimes lives when he should have died. Dr. Evans is now a believer, but he tries to convince Gramps to let Death down so people who are suffering can find release. Gramps refuses, so the doctor arranges for the local sheriff to commit Gramps while Pud is delivered to Demetria's custody. With the help of his housekeeper (Una Merkel), Gramps tricks both of them into believing they are scheduled to go with Mr. Brink when he comes down from the tree. They beg Gramps to convince Brink otherwise, and Demetria vows never to bother Gramps or Pud again. Gramps realizes that sooner or later he will have to let Brinks downDeath is an ultimately unavoidable part of life. He tries to say goodbye to Pud, who reacts angrily and tries to run away. Mr. Brink sees Pud in the yard and dares him to climb the tree. Pud gets over the fence Gramps has had built around the tree, but falls and is crippled for life. Distraught, Gramps lets Death down from the tree. He takes both Gramps and Pud, who find they can walk again. In the final scene, they walk together up a beautiful country lane and hear Granny Nellie calling to them from beyond a brilliant light. 
 Question: Who dares Pud to climb a tree?
