Q: Context: A joint is a point at which two or more bones meet. There are three main types of joints in the body: 1. Fixed joints do not allow any bone movement. Many of the joints in your skull are fixed ( Figure 1.1). There are eight bones that fuse together to form the cranium. The joints between these bones do not allow movement, which helps protect the brain. 2. Partly movable joints allow only a little movement. Your backbone has partly movable joints between the vertebrae ( Figure 1.2). The skull has fixed joints. Fixed joints do not allow any movement of the bones, which protects the brain from injury. 3. Movable joints allow the most movement. Movable joints are also the most common type of joint in your body. Your fingers, toes, hips, elbows, and knees all provide examples of movable joints. The surfaces of bones at movable joints are covered with a smooth layer of cartilage. The cartilage reduces friction between the bones. Ligaments often cross a joint, holding two nones together. For example, there are numerous ligaments connecting the leg bones across the knee joint. Four types of movable joints are discussed here. 1. In a ball-and-socket joint, the ball-shaped surface of one bone fits into the cup-like shape of another. Exam- ples of a ball-and-socket joint include the hip ( Figure 1.3) and the shoulder. 2. In a hinge joint, the ends of the bones are shaped in a way that allows motion in two directions, forward and backward. Examples of hinge joints are the knees ( Figure 1.4) and elbows. 3. The pivot joint ( Figure 1.5) only allows rotating movement. An example of a pivot joint is the joint between the radius and ulna that allows you to turn the palm of your hand up and down. 4. A gliding joint is a joint which allows only gliding movement. The gliding joint allows one bone to slide over the other. The gliding joint in your wrist allows you to flex your wrist. It also allows you to make very small side-to-side motions. There are also gliding joints in your ankles. 
 Question: what type of joint allows you to turn the palm of your hand?

A: a pivot joint

Q: Context: Police officers Brian Taylor (Jake Gyllenhall) and Mike Zavala (Michael Pena) are close friends and partners in the Los Angeles Police Department. Taylor is filming their police activities for a film project, attaching small cameras to his and Zavala's uniforms and carrying around a camcorder, much to the dismay of their peers and superiors. After shooting two suspects following a high speed chase, the shooting is declared justified by the D.A. and the officers are commended for their actions. Taylor and Zavala's antics are met with scorn by fellow officer Van Hauser (David Harbour).The officers respond to a call regarding a man, Mr. Tre (Cle Shaheed Sloan) scaring off a mailman while intoxicated. Upon arrival, Tre hurls racist insults at the Hispanic Zavala, who responds by accepting a fight, to Taylor's approval. Zavala beats him soundly and arrests him, but wins the man's respect for both fighting fair and not mentioning the fight in the report (which may have sent Tre to prison for life due to Three Strikes). Later that night, Tre and his friends are shot at by a group of Latino gang members and one of his friends is killed. The officers find the now-burnt vehicle used in the drive-by the next day, but are shooed off the scene by homicide detectives as well as Van Hauser, who warns them they will get screwed over by the LAPD someday.Responding to a missing persons report, the officers discover two children bound and locked away in a closet and arrest the distressed mother and her drug-addict husband.The cops arrive as a group at a loud outdoor party, the Hispanics from the drive by shooting are celebrating. The cops and partiers verbally joust and Brian sizes up the gang leader, Big Evil (Maurice Compte). The cops depart telling them to keep the noise down.Taylor begins dating Janet (Anna Kendrick) and feels Janet is the only girl he's dated who can connect with him on an intellectual level. Zavala, who is married and expecting a child, offers him relationship advice.Investigating the South Central area, Taylor has a hunch and determines to scope out the home of the mother of a known gang member and sees an expensive pick up truck in the driveway. A woman walks out of the house and delivers a large soup saucepan with lid to the man in the truck. As the truck drives away, the officers follow and then pull over the man in the truck, ostensibly for having CD hanging off the mirror and illegally obstructing the front view, which is minor traffic violation in California per VC 26708 . As Zavala approaches the driver's window to make contact, the driver suddenly draws a gun and fires, and Zavala deflects the man's arm just in time to avoid being shot. After arresting the driver, the officers find an ornately-decorated, compact .45 Colt automatic pistol, a gold-plated AK-47 rifle, and a large amount of money in his truck (hidden in the soup pot). As revealed later, the money and firearms are connected to a Mexican drug cartel operation in the South Central area as well as the gang that did the drive-by on Tre and others.Days later, the two officers are first responders at a house fire that has trapped children on the second floor. Zavala and Taylor enter the house and rescue two young children and are nearly overcome by heat and smoke. When the mother informs them that a third child remains inside, Zavala to rushes to the aid of the remaining child as Taylor reluctantly follows, barely making it out alive. The two are commended and receive the Medal of Valor for their actions, but Taylor has mixed emotions about the situation. Using the house fire incident as leverage, Taylor convinces Zavala to further investigate the South Central incident, to Zavala's chagrin. Arriving at the house, Taylor and Zavala notice suspicious behavior from outside and enter. They arrest another man, who is also in possession of several ornate firearms: a .45 Colt automatic similar to the first one found at the traffic stop, and a Walther PPK. Investigating further, Taylor discovers a hidden stash of Mexican and Asian 
 Question: Whose body shielded Taylor's?

A: zavala's

Q: Context: The film depicts the construction and ultimate demolition of a metaphorical wall. Though the film's symbolism is open to interpretation, the wall itself clearly reflects a sense of isolation and alienation.Pink (Bob Geldof), the protagonist (and unreliable narrator) of the film, is a rock star, one of several reasons behind his apparent depressive and detached emotional state. He is first seen in a quiet hotel room, having trashed it. The opening music is not by Pink Floyd, but is the Vera Lynn recording of "The Little Boy that Santa Claus Forgot". During the following scenes, it is revealed that Pink's father, a British soldier, was killed in action during World War II during Pink's infancy. The reference is almost certainly to the death of Roger Waters' real-life father, Eric Fletcher Waters, who died in combat in Italy during Operation Shingle (the Battle of Anzio) in February 1944.The movie then flashes back to Pink as a young English boy growing up in the early 1950s. Throughout his childhood, Pink longs for a father figure after he learns his father died in the war. At school, he is humiliated by his mean and stern teacher for writing poems in class. The poems that the teacher seizes from him and reads aloud are lyrics from "Money" from the Pink Floyd album Dark Side of the Moon. Pink is also affected by his overprotective mother who spoils him by giving him whatever he wants.As an adult, Pink eventually gets married as his fame as a rock star grows, but he and his wife grow apart and she has an affair while Pink is on tour. When Pink learns of the affair, he compensates with expensive materialistic possessions and turns to a willing groupie (Jenny Wright), whom he brings back to his hotel room only to trash it in a fit of violence, causing her to flee the room in terror.Pink slowly begins to lose his mind to metaphorical "worms". He shaves off all of his body hair (an incident inspired by former bandmate Syd Barrett, who appeared at a 1975 recording session of Wish You Were Here, having shaved his eyebrows and body hair) and, while watching The Dam Busters on television, morphs into his neo-Nazi alter-ego. Pink's manager (Bob Hoskins), along with the hotel manager (Michael Ensign) and some paramedics, break into the hotel room and discover Pink. They take him away into a waiting limousine outside the hotel and inject him with drugs to enable him to perform.The drugs cause Pink to hallucinate and he fantasises that he is a neo-Nazi dictator, his concert is a rally. His followers proceed to attack ethnic minorities and rape the white girlfriend of a black man. Later, Pink holds a rally in suburban London, singing "Waiting for the Worms". The scene is inter-cut by images of animated marching hammers that goose-step across ruins.Pink screams "Stop!" and takes refuge in a bathroom stall at the concert venue, reciting poems which would later be used as lyrics on Pink Floyd's "Your Possible Pasts" from The Final Cut album and "5:11 AM (The Moment Of Clarity)" from Roger Waters' The Pros and Cons of Hitch Hiking.In a climatic animated sequence, Pink puts himself on trial. He is depicted as a small, pink rag doll that rarely moves. The judge is a giant pair of buttocks, with two backward facing legs, an anus for a mouth and a scrotum for a chin. The lawyer is a tall, menacing, vulturelike man and the schoolmaster is an abusive, hateful marionette. After hearing from the parties and witnesses (Pink's wife and mother), the judge orders the wall to be torn down. The wall explodes and shows a montage of events from the entire film.The film concludes with three children cleaning up a pile of debris after an earlier riot. It is unknown whatever has happened to Pink, leaving the viewer to decide. 
 Question: Who sang "The Little Boy that Santa Claus Forgot"?
