I'm taking a test and have to guess the right answer to the question after the article. Article: The United States is faced with serious traffic problems. Too many cars travel on the freeways to and from the city. This heavy traffic causes delays and lots of pollution from cars that are using their engines but not moving anywhere. Many cars going nowhere is called a "traffic jam." While many cities in the United States have traffic problems, some of the worst are in Los Angeles, California. Los Angeles is a big city with a large downtown area. One of the reasons why there is so much traffic is that few people use public transportation to get around Experts say one possible solution to the traffic problem in Los Angeles would be to make people want to use the public transportation system of buses instead of their own cars. People say the buses should be made easier, faster, less costly and more dependable than driving a car. One suggestion is to reduce the cost of riding the bus. People who usually drive their cars could save a lot of money on gas and parking costs. Also, Los Angeles could make the buses easier for people to use. The buses could travel to more places in the city. And there could be more special lanes on the freeways that only buses could drive in. These changes would make taking the bus faster and easier than driving a car. Other experts have said that the best way to ease traffic problems is to charge people money to drive on the freeways. These charges, or tolls, would be for the most crowded roads. The tolls would be in effect during the times of day when most people drive to work and home again. These times in the morning and late afternoon are called "rush hour". People would try to avoid driving on these roads, which would decrease the amount of traffic. Also ,the money collected from these tolls could be used to improve the roads and public transportation system. Question: According to the passage, if the solutions were carried out, _ Options: A: more cars would be reduced and more roads would be built B: it would be easier but slower to take buses than to drive cars C: many people would prefer to walk around rather than drive cars D: the roads and public transportation system would be greatly improved

I'm taking a test and have to guess the right answer to the question after the article. Article: Three-dimensional printers are fast becoming everyday devices in the United States. Three-D printers are used to make everything from automobile parts to bone replacements for human patients. American research scientists are now working on creating replacements for living tissue. Researchers at the Medical University of South Carolina have been working on creating and manufacturing living tissue since 2003.This process is called biofabrication . It requires special printing equipment and a special kind of ink. Traditional printers require ink to produce an image or design on a piece of paper. For their three-D printer, the South Carolina researchers prepare complex nutritious solutions they call bio-inks. Bio-inks are made of proteins and glucose , which normally provides energy for most cells of the body. The researchers also add living cells taken from the animal that will receive the new, printed tissue. The bio-inks are then added to a device that researchers call the Palmetto bio-printer. Sarah Grace Dennis is one of the researchers at the Medical University of South Carolina. She says new technology, like the Palmetto bio-printer, is a great help to the biofabrication process. The bio-inks are placed in three dispensers , containers, inside the printer. Lasers control both the position of the printing surface and the places where the bio-ink is released. Michael Yost is a leader of the research team. He says the printing process is fully automated-- machine-operated. He says that the Palmetto bio-printer makes it possible to create complex tissue types. The researchers say bio-printing is still experimental. But they hope in a few years they may be able to print tissue to replace damaged human organs. But there are still some problems which need to be solved. Some scientists worry about how to get blood to the replacement tissue. The flow of blood is important to keep the printed tissue alive. Michael Yost hopes that more people will believe in the benefits of biofabrication. "Tissue... Question: According to Michael Yost, we can infer that _ . Options: A: the Palmetto bio-printer can workwithout power B: the Palmetto bio-printer has been used to treat the patients C: the Palmetto bio-printer can only be found in the United States D: the Palmetto bio-printer will have a bright future in medical use

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: It is easy to find your way about in New York. It is _ so regularly. Instead of streets winding and twisting as they do in London, they are all regular and well planned. The streets running north and south are called "avenues" and are numbered, e.g. 1stAvenue, 2ndAvenue, etc. The streets going east and west are called "streets" and are also numbered, e.g. 51stStreet, 63rdStreet. It is all much more logical than London's street names. But I couldn't help thinking how much more interesting than these dull cold numbers are London's illogical but colorful names of streets, e.g. "Bishopgate" (which is not a gate and hasn't a Bishop in it); "Haymarket" or "Corn market" (where you won't see any hey or corn) or "Poultry" (without a living chicken anywhere in sight) or "Thread needle Street" (where you won't find little girls learning to sew). Question: According to the writer's opinion, _ . Options: A: avenues and streets are the same B: streets in America are better than avenues in England C: streets in New York are better than those in London D: the writer didn't agree with the London streets planners
A: D

I'm taking a test and have to guess the right answer to the question after the article. Article: My son loves video games very much. He spends hours every day playing video games in his room. Is there anyredeeming educational value to video games? Some seem like they could help him learn strategy. But I worry others may be too violent ornumb his mind. Cecilia Some games may improve kids' hand-eye coordination and problem-solving skills. Games that require kids to actually move ormanipulate the game through their own physical movement can even get _ kids moving, though not as much as they could if they actually played outside or participated in sports or other outdoor acuities. Others, though, don't have such benefits, and violent video games have been shown that they might increase kid's aggressive behavior. Like a lot of aspects of raising kids, when it comes to video games, the healthiest approach is actually self-control. The American academy of Pediatrics(AAP) recommends that kids should spend no more than 2 hours each day on screen time, including watching TV or movies, or playing computer or video games. So consider setting limits at least that strict to keep game playing from affecting their schoolwork, household responsibilities, and the physical activity your son needs very day. Make sure that he's playing games which are suitable for his age group. All video games are rated and labeled by the Entertainment Software Rating Board. Steer clear of any rated "M" for mature. Those are for ages 17 and older and can contain heavy-duty violence, strong language, and sexual content. Try to keep the video gameconsole in a common area of the house, not your son's room. That way you can catch any inappropriate content in the games he's playing, and he'll be in a position to interact with others in the house while he's playing. Make sure your son has appealing alternatives, too, such as sports, activities, opportunities to socialize with peers; and downtime to be creative. If you continue to have concerns about his video game activity, talk with your doctor. Reviewed by:Mary L. Gavin, MD Question: Which is the best title of this passage? Options: A: Should children play video games? B: Kids' playing video games is harmful. C: Is playing video games good for kids? D: Help children choose video games.
