It's an interesting and exciting new improvement in today's world as we look for better ways to protect the quality of the air we breathe and conserve our natural resources. The quality of our air is affected by many different things. But one of the largest sources of air pollution is the burning of fossil fuels such as coal and gasoline which are used to power a car's engine. The EPA has set national standards to help control the level of harmful pollutants sent off into the air, and the automobile industry has acted by producing a hybrid car that uses less gas and therefore causes less pollution. A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery powered. Some people tend to think that since the hybrid car is partially electric, you have to plug it in to charge it. But that's not how it works. The 144 volt battery pack is actually recharged( ) through the energy that is produced when the car's brakes are used. This is referred to as "regenerative braking", because it generates electricity. Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car. When the driver stops at a traffic light, the engine automatically ( ; )shuts off to save fuel. Then, as soon as the driver puts the car in gear and touches the gas pedal, the engine starts back up. Have you ever ridden in a car with someone who ran out of gas? That probably wouldn't happen if you were riding in a hybrid car. It flashes a warning on its computer screen that says, "I am low on gas". When it completely runs out, the warning reads, "YOU ARE NOW OUT OF GAS!" Then the electric power supply kicks in to let the driver travel a few more miles to a gas station. Question: According to the passage, the word "hybrid" refers to _ . - a high tech discovery - energy saving - a new invention - a combination of two things
a combination of two things

Read the following article and select the best answer. Article: Is It Worth Buying Organic Food? Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels . However, if you think paying a little more for organic food gets you a more nutritious and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren't necessarily more nutritious, and they're no less likely to suffer from disease-causing bacteria, either. The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. "We did not find strong evidence that organic food is more nutritious or healthier," says Dr. Crystal Smith-Spangler from Stanford. "So consumers shouldn't assume that one type of food has a lower risk or is safer." For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats. While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends. Organic food is produced with fewer chemicals and more natural-growing practices, but... Question: The new research questions whether organic food _ . - should replace traditional food - has been overpriced by farmers - is grown with less harmful chemicals - is really more nutritious and healthier
is really more nutritious and healthier

Read the following article and select the best answer. Article: How do you celebrate New Year's Day? If I had to take a guess, you probably celebrate New Year's Day surrounded by family and friends, enjoying drinks of your choice (probably wine and champagne) and watching the ball drop. If you're particularly lucky, perhaps you share a kiss with that special someone when the clock hits 00:00am. Have you ever imagined how New Year's Day would look in another country? Listed below are five of the top ten "Unique New Year Traditions from Around the World." 1. Breaking Dishes on Neighbor's Door----Denmark A strange and weird Danish New Year tradition, depending on how you look at it, is throwing dishes at neighbor's door. Strangely, this makes them happy instead of annoying them. The family with the tallest tower of broken plates, glasses, cups and other crockery is considered to be the luckiest person because it symbolizes their large amount of loyal friends. 2. Talking to Spirits----Mexico Talking to spirits is a part of Mexican belief. Mexicans strongly believe that they can communicate with the souls of their dead loved ones. New Year's Eve is considered the best time to communicate with dead spirits to convey a message or ask for guidance. And this is not done at home on an individual basis but is a legal Mexican practice. Taos Inn, in New Mexico for example, offers 15 minutes session of spiritualism and meditation for $15. Not a bad price for some helpful guidance! 3. Wearing Polka Dots ----Philippines Imagine streets full of people wearing polka dots and dining room tables full of round shaped food and fruits on one single day of the year. This all actually happens in the Philippines on New Year's Eve every year. Philippines believe that this will bring them prosperity by associating the round dots to coins and wealth. 4.
