question:
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?
answer:
zavala's

Context: The ability to see is called vision. It depends on both the eyes and the brain. The eyes sense light and form images. The brain interprets the images formed by the eyes and tells us what we are seeing. For a fascinating account of how the brain helps us see, watch this short video: . MEDIA Click image to the left or use the URL below. URL: Did you ever use 3-D glasses to watch a movie, like the teens in Figure 20.11? If you did, then you know that the glasses make images on the flat screen seem more realistic by giving them depth. The images seem to jump right out of the screen toward you. Unlike many other animals, human beings and other primates normally see the world around them in three dimen- sions. Thats because we have two eyes that face the same direction but are a few inches apart. Both eyes focus on the same object at the same time but from slightly different angles. The brain uses the different images from the two eyes to determine the distance to the object. Human beings and other primates also have the ability to see in color. We have special cells inside our eyes that can distinguish different wavelengths of visible light. Visible light is light in the range of wavelengths that the human eye can sense. The exact wavelength of visible light determines its color. The function of the eye is to focus light and form images. We see some objects, such as stars and light bulbs, because they give off their own light. However, we see most objects because they reflect light from another source such as the sun. We form images of the objects when some of the reflected light enters our eyes. Look at the parts of the eye in Figure 20.12. Follow the path of light through the eye as you read about it below. 1. Light from an object passes first through the cornea. This is a clear, protective covering on the outside of the eye. 2. Then light passes through the pupil, an opening in the center of the eye. The pupil, which looks black, is surrounded by the colored part of the eye, called the iris. 3. Light entering through the pupil next passes through the lens. The lens is a clear, curved structure, like the lens of a magnifying glass. Along with the cornea, the lens focuses the light on the back of the eye. 4. The back of the eye is covered by a thin layer called the retina. This is where the image of the object normally forms. The retina consists of special light-sensing cells called rods and cones. Rods sense dim light. Cones sense different colors of light. 5. Nerve impulses from rods and cones travel to the optic nerve. It carries the nerve impulses to the brain. You probably know people who need eyeglasses or contact lenses to see clearly. Maybe you need them yourself. Lenses are used to correct vision problems. Two of the most common vision problems in young people are myopia and hyperopia. You can compare myopia and hyperopia in Figure 20.13. To learn about astigmatism, another common vision problem, watch this very short video: . MEDIA Click image to the left or use the URL below. URL: Myopia is commonly called nearsightedness. People with myopia can see nearby objects clearly, but distant objects appear blurry. Myopia occurs when images focus in front of the retina because the eyeball is too long. This vision problem can be corrected with concave lenses, which curve inward. The lenses focus images correctly on the retina. Hyperopia is commonly called farsightedness. People with hyperopia can see distant objects clearly, but nearby objects appear blurry. Hyperopia occurs when images focus in back of the retina because the eyeball is too short. This vision problem can be corrected with convex lenses, which curve outward. The lenses focus images correctly on the retina. Vision is just one of several human senses. Other human senses include hearing, touch, taste, and smell. Imagine shopping at the fruit market in Figure 20.14. It would stimulate all of these senses. You would hear the
