I'm taking a test and have to guess the right answer to the question after the article. Article: Many countries have passed safety laws that require seat belts in vehicles. A modern three-point seat belt, also called a safety belt, is a harness to prevent the driver or a passenger from flying forward and hitting hard against the interior of a vehicle during a collision. A modern seat belt will help to position you properly to gain maximum benefit from your car's airbags that will inflate during a collision. Using a seat belt also prevents you from being ejected from a car into the path of oncoming traffic. Research shows that when you wear a modern seat belt, you reduce the risk of death or serious injury by 70% or more during an auto accident. Seat belts have existed in different forms since the early days of automobiles, and they have changed from a single lap belt to the three-point seat belt we use today. In 1911 the first airplane seat belt was installed. Then, in the 1920's they were used in racecars. By the 1930s, a group of American physicians created lap belts for their own vehicles and urged vehicle manufacturers to provide seat belts on all vehicles. Dr. C. Hunter Shelden made a major contribution to our safety with his article in the November 5, 1955 Journal of the American Medical Association (JAMA). He strongly encouraged the manufacture and use of door locks, airbags, and retractable seat belts, like the ones we use today. The modern three-point seat belt, including a lap belt and a shoulder belt, was introduced as standard equipment on Volvo cars in 1959. In 1970, the state of Victoria in Australia made the wearing of a seat belt compulsory for every car driver and front-seat passenger. Today many countries have also mandated the use of five-point safety harnesses for carefully designed child safety seats that can protect a child during a serious car accident. An airbag is a Supplemental Restraint System, or SRS, and consists of a rapidly inflatable restraint cushion that works together with a seat belt to protect you during a collision. Modern cars often contain several airbags in... Question: This article mostly deals with _ . Options: A: how to drive safely on the road B: different forms of seat belts C: the history of seat belt development D: the importance of seat belt use

I'm taking a test and have to guess the right answer to the question after the article. Article: What are some of the steps a person can take to prevent his house from being broken in while he or she is away? One step is to make sure that the house has a _ look. Living room shades could be pulled down only half-away. Bedrooms that usually have the shades pulled down at night should be left down. Another is to make sure that all outside looks are the dead-belt type. Still another is to leave several low-watt lights burning and make sure that one is in the kitchen. Lights that turn on and off automatically are the best. Then, too, it is a good idea to leave a radio turned into a talking station. Any type of conversation makes a burglar think twice before trying to enter. Finally, while away on vacation, make sure that nothing collected in the front or back of the house. Make certain that the newspaper is stopped and that a trusted neighbor has been asked to pick up the posts. Question: Why is it a good idea to leave the radio turned to a talking station? Options: A: So one won't feel lonely or afraid. B: So a burglar can't be sure whether or not there's a person in the house. C: To keep well-informed about the presence of thieves. D: Because the music stations are too loud.

I'm taking a test and have to guess the right answer to the question after the article. Article: When scientists accidentally killed what turned out to be the world's oldest living creature, it was bad enough. Now, their mistake has been worsened after further research found it was even older - at 507 years. The ocean quahog, a type of deep-sea clam, was dredged alive from the bottom of the North Atlantic near Iceland in 2006 by researchers. They then put it in a fridge-freezer, as is normal practice, unaware of its age. It was only when it was taken to a laboratory that scientists from Bangor University studied it and concluded it was 400 years old. The discovery made it into the Guinness Book of World Records. However, by this time, it was too late for Ming the Mollusc , named after the Chinese dynasty when its life began. Unfortunately researchers who calculated Ming's age killed it instantly by opening its shell. The researchers opened the ancient clam up to judge its age by counting growth rings inside. But the rings were so close together that scientists ended up having to count the rings on the outside to be accurate, leading CBS journalists to point out that if scientists had just started there, Ming could have lived on. Now, after examining the quahog more closely, using more advanced methods, the researchers have found the animal was actually 100 years older than they first thought. Dr Paul Butler, from the University's School of Ocean Sciences, said: "We got it wrong the first time and maybe we were a bit hasty publishing our findings back then. But we are absolutely certain that we've got the right age now." The mollusc was born in 1499 - just seven years after Columbus discovered America and before Henry VIII had even married his first wife, Catherine of Aragon in 1509. A quahog's shell grows by a layer every year, in the summer when the water is warmer and food is plentiful. It means that when its shell is cut in half, scientists can count the lines in a similar way that trees can be dated by rings in their trunks. Jan Heinemeier, associate professor at the University of Denmark, who... Question: At first, the scientists found that _ . Options: A: The ocean quahog got a deadly disease B: The growth rings inside were so close together C: it was accurate to count the growth rings outside D: The ocean quahog was 400 years old
