INSTRUCTIONS: Edit the following paragraphs for consistent point of view only. Using the first sentence as the basis for the point of view, change the rest of the paragraph to maintain a consistent point of view. Do not edit for any other kinds of changes. Over the years, I have loved riding motorcycles because of the sense of freedom that comes from riding them. When I was a youngster, you
dreamed of having a motorcycle of your own. I decorated my room with posters of Marlon Brando, Steve McQueen, and Peter Fonda, all sitting on their motorcycles. I got my first motorcycle when you began riding your brother's Honda after he went into the service. Later, I bought a bigger Honda that you drove until I went into the service myself. Years later, as a junior in college, you bought my biggest Honda and drove it all the time. Unfortunately for me, I had an accident that stopped you from riding again for eighteen years. However, in March of 2007, you felt the longing to ride so strongly that I bought a 1992 Harley Sportster, and I am enjoying every minute you are on it. What will be an ideal response?
Read the textbook passage on the next page and then answer the questions that follow by choosing the letter of each correct response.
The “Fourth Law of Motion”: The Automobile Air Bag A major automobile safety feature is the air bag. Seat belts restrain you so you don’t follow along with Newton’s first law of motion (“An object will remain at rest or in uniform motion in a straight line unless acted on by an external, unbalanced force”) when the car comes to a sudden stop. But where does the air bag come in, and what is its principle? When a car has a head-on collision with another vehicle or hits an immovable object such as a tree, it stops almost instantaneously. Even with seat belts, the impact of a head-on collision could be such that seat belts might not restrain you completely, and injuries could occur. Enter the air bag. This balloon-like bag inflates automatically on hard impact and cushions the driver. Passenger-side air bags are becoming more common, and back-seat air bags are available. The air bag tends to “cushion” or increase the contact time in stopping a person, thereby reducing the impact force (as compared to hitting the dashboard or steering column). Also, the impact force is spread over a large general area and not applied to certain parts of the body as in the case of seat belts. Being inquisitive,1 you might wonder what causes an air bag to inflate and what inflates it. Keep in mind that this must occur in a fraction of a second to do any good. (How much time would there be between the initial collision contact and a driver hitting the steering wheel column?) The air bag’s inflation is initiated by an electronic sensing unit. This unit contains sensors that detect rapid decelerations,2 such as those in a high-impact collision. The sensors have threshold settings so that normal hard braking does not activate them, and they are equipped with their own electrical power source because, in a front-end collision, a car’s battery and alternator are among the first things to go. Sensing an impact, a control unit sends an electric current to an igniter in the air bag system that sets off a chemical explosion. The gases (mostly nitrogen) rapidly inflate the thin nylon bag. The total process of sensing to complete inflation takes about 25 thousandths of a second (0.025/s). Pretty fast, and a good thing, too! However, a recent concern about air bags is the injuries and deaths resulting from their deployment.3 An air bag is not a soft, fluffy pillow. When activated, it comes out of the dashboard at speeds of up to 200 miles per hour and could hit a person close by with enough force to cause severe injury and even death. Therefore, adults are advised to sit at least ten inches from the air bag cover. This allows a margin of safety from the two- to three-inch “risk zone.” Seats should be adjusted to allow for the proper safety distance. Probably a more serious concern is associated with children. Children may get close to the dashboard if they are not buckled in or not buckled in securely so that they can see. Another bad situation is using a rear-facing child seat in the front passenger seat. An inflating air bag could have serious effects. Sometimes it may be impossible to follow these safety rules. So air bag deactivation4 may be authorized for one of four reasons. A rear-facing child restraint might need to be placed in the front seat because the car either has no back seat or has one that is too small. A child 12 years old or younger might need to ride in the front seat because of a medical condition that requires frequent monitoring. An individual who drives (or rides in the front seat) might have a medical condition that would make it safer to have the air bags turned off. A driver might need to sit within a few inches of the air bag (typically because of extremely short stature, 4 feet 6 inches or less). Specific problems may exist, but air bags save many lives. All new passenger cars must have dual air bags, and manufacturers are beginning to install air bags that inflate with less force, so as to reduce the possibility of injuries. Even if your car is equipped with air bags, however, always remember to buckle up. (Maybe we should make that Newton’s “fourth law of motion.”) 5. Is the opinion stated in paragraph 8 informed or uninformed? a. informed b. uninformed 6. What is the implied main idea of paragraph 4? a. Seat belts aren’t as effective as air bags. b. People should drive more carefully. c. Automobile manufacturers could make cars safer from impacts. d. Air bags protect people from injuries. 7. Which of the following sentences is NOT a major supporting detail in paragraph 9? a. “So air bag deactivation may be authorized for one of four reasons.” b. “A rear-facing child restraint might need to be placed in the front seat because the car either has no back seat or has one that is too small.” c. “A child 12 years old or younger might need to ride in the front seat because of a medical condition that requires frequent monitoring.” d. “An individual who drives (or rides in the front seat) might have a medical condition that would make it safer to have the air bags turned off.” 8. Which of the following inferences can you make based on the information in paragraph 3? a. New cars have too many airbags. b. Air bags are not easy to pop. c. Air bags installed in the front seat have proven to be effective. d. Auto manufacturers think drivers are more important than passengers.
