I'm taking a test and have to guess the right answer to the question after the article. Article: Americans won't live without cars! Each year there is an increasing number of cars on roads and streets, as millions of new cars are produced. One out of every six Americans work at putting together the parts of cars, driving trucks, building roads or filling cars with gas. Most Americans find it hard to think what life would be without a car. However, some have realized the serious problem of air pollution by cars. The polluted air is poisonous and dangerous to health. One way to get rid of the polluted air is to design a new car that does not pollute. That's what several large car factories are trying to do. But to build the new car is easier said than done. Progress in this field has been slow. Another way is to take place of the car engine by something else. Engineers are now working on some new cars. Many makers believe that it will take years to develop a practical model that pleases man. To prevent the world from being polluted by cars, we'll have to make some changes in the way many of us live. Americans, for example, have to cut down the number of their cars they are encouraged to travel and go to work by bike. Riding a bike is thought to help keep the air clean. But this change does not come easily, a large number of workers may find themselves with no jobs if a car factory closes down. And the problem of air pollution would become less important than that of unemployment. Question: Large car factories are trying to build a clean car, _ Options: A: which is clean itself B: which does not pollute the air C: which is used to clean streets D: which is easier to make

I'm taking a test and have to guess the right answer to the question after the article. Article: According to the US Geological Survey, about seven million earthquakes strike worldwide every year--but fortunately, only about 1500 of these are of a magnitude of 5 or greater on the Richter scale. Certain areas, such as California and Japan, are more _ earthquakes than others. Although the chance of being caught in "The Big one" is remote, it's wise to be prepared if you live in a region where earthquakes are common. Educate your family about earthquakes before a big one strikes. For example, they need to know to take shelter in a doorway or under a strong object if indoors, and never to run outdoors if they are inside. If outside, they need to know to stay away from power lines and buildings where objects could fall. Teach family members how to turn off gas or water lines or electrical power that may need to be shut off after a quake if severe damage occurs. Develop a plan. Where will your family meet in the event of a disaster? What if some people are at work or school? How will you know if they are safe? Where will you all meet up? Pack a preparedness kit and keep it in a safe location. In a major earthquake, it's possible that you won't be able to get into your house. Keep supplies in your car trunk or an outside storage shed if possible. Pack whatever your family is likely to need, enough for three days to a week, including food, water, medication, first aid and personal hygiene supplies, flashlights, a portable radio, blankets, clothes and shoes, cash, or camp stove, candles, matches or lighters, and a whistle. Consider earthquake insurance for your home if you live in an earthquake-prone area. Regular homeowner's insurance doesn't cover earthquake damage. Question: What would be the best title for the passage? Options: A: How to Keep Safe in an Earthquake B: How to Prepare for an Earthquake C: Who Can Help Us After an Earthquake? D: Where Is an Earthquake-prone Area?

I'm taking a test and have to guess the right answer to the question after the article. Article: Sometimes,you just can't help it.Maybe you're watching a sad movie,or thinking about the friend who moved away.Next thing you know,your eyes are watering,and you have tears running down your cheeks.Why do people cry when they are emotional? What are tears? Scientists are working hard to find the answers to these questions. Ad Vingerhoets is a professor of psychology at Tilburg University,in the Netherlands.He is one of the few scientists in the world who have studied crying.According to Vingerhoets,there are three types of tears.Basal tears are the first type.They lubricate the eyes and act as a protective barrier between the eye and the rest of the World.Next are reflex tears.They wash your eyes clean when something gets in them.Finally,there are emotional tears. "These are released in response to emotional states,"explains Vingerhoets."Especially when we feel helpless." Scientists believe that crying has something to do with how humans developed and learned to depend on each other."Humans are very complex social creatures,"says Lauren Bylsma,a professor at the University of Pittsburgh,in Pennsylvania."It seems that tears serve to arouse help and support from others,''She says."Another reason we weep is that humans have the longest developmental period of almost any animal.It takes a long time to grow up." Vingerhoets agrees."I think that the reason why humans shed tears has something to do with our childhood,"he says."That's the time when we are stir dependent on adults for love and protection and care.The major advantage of emotional tears is that you can target them at a specific person."Vingerhoets says this ability to target someone could have come in hand in prehistoric times,when humans were living among dangerous animals.Crying could attract predators .Tears were a safer way to get attention.In this case,it is better to use a silent signal to ask for help,"he says. Vingerhoets and Bylsma do frequent studies to better understand why humans cry.According to Byhma,there is still much more to... Question: Which of the following is reflex tears? Options: A: Tears when eyes are dry. B: Tears moved by a story. C: Tears released when crying. D: Tears when dirt gets into eyes.
