Read the following article and select the best answer. Article: While shopping for my groceries a few years ago, I decided on an idea to buy one of those little potted basil plants instead of the package of basil leaves. It was about the same price and I figured I would plant it in my yard and maybe get a few meals worth out of it before it died. Little did I know that the little $4 basil plant would survive for almost 3 years and provide enough fresh basil for at least 2-3 meals per month (that's about 60 basil-filled meals)! What I learned was that the plant likes quite a bit of sun and warm temperatures (it went nearly into rest in the winter when temperatures in Arizona drop to below zero overnight). My husband and I had enjoyed so many meals with fresh basil that after the original one died, we immediately got another basil plant to replace it. If you like to cook, you know that basil fresh off the plant transforms a good meal into an amazing one. To make the case for always keeping a basil plant in our yard even stronger, I just opened the latest issue of All You magazine and saw this picture of a beautiful basil plant. Then I read the first sentence of the accompanying article, "Did you know a basil plant can produce nearly $80 worth of leaves each year?" I knew that I had gotten my money's worth from the little plant, but I had no idea that I saved about $200 in the time I had that plant. $4 to produce $200? That's a great return on investment no matter how you slice it! Whether you buy your live herbs as seeds or plants, and plant them in coffee cans or your front yard, growing herbs can be a great way to save money and enjoy even better-tasting meals. Try it for yourself and see how much you can enjoy fresh herbs in your meals. Question: We know from the text that Basil _ . - will survive for more than 3 years - must be planted in your front yard - can produce $80 worth per month - can become meals after being planted
**Answer**
can become meals after being planted

Read the following article and select the best answer. Article: You've bought what you need. The grocery cashier asks, "Will that be paper or plastic? You reply "Plastic, please." This seems like a simple question and there are plenty of reasons we choose plastic: easier to carry, lighter than paper bags, possibly less damaging to the environment, less expensive to the shop owners, able to be used as trash bag, and so on. There are different opinions on plastic and paper. Now let's follow the travels of 3 plastic bags. It begins at the grocery store with the customer's choice. Plastic Bag 1: As the waste engineer come by and pick up the trash, the first plastic bag falls out. It sits on a small street for a couple of hours until a car comes along and takes it down to the road. Then a gust of wind blows it across the road, then another car, then another gust of wind finally makes its way to the beach. Water fills the plastic bag and makes it look like a jellyfish. A seal swims by, thinking it looks very interesting, and swallowed it. The plastic bag may stay in the seal's stomach for months, maybe years. You see, our lovely animals have been living thousands of years in a world where everything can be eaten. Plastic Bag 2: This bag does make its way to landfill . Before they have a chance to cover up the thousands of pounds of daily waste, a strong wind comes up and blows these plastic bags out of the landfill. Once the wind stops, workers will be sent to collect thousands of bags around. But they can't possibly get them all. So our little bag continues his adventure getting caught in trees, eaten by birds or making its way to our lakes or rivers. Plastic Bag 3: The last bag also blows away but is caught in a landfill where it sits for many years, as all the trash is wrapped in a big plastic bag, making natural degradation impossible. Although workers do much work to make sure water and air system won't be polluted, some do. Guess what, plastic bags are made from petrol, a harmful waste material, which in one way or another makes its way to the environment. Another...

Read the following article and select the best answer. Article: Air pollution is a leading cause of cancer and classified among Group 1,or top, human carcinogens , said the International Agency for Research on Cancer (IARC), which is the World Health Organization's (WHO) cancer agency, on Oct 17,2013. The most widely used system for classifying carcinogens comes from the IARC, which places them into five groups. Group 1 carcinogens definitely cause cancer in humans. Group 2A is probably carcinogenic to humans, Group 2B is possibly carcinogenic, the carcinogenicity of Group 3 in humans is unclassifiable, and Group 4 is probably not carcinogenic to humans. Only a little more than 100 are classified as Group 1 cancer-causing substances, including ultraviolet radiation and tobacco smoke. "Our task was to evaluate the air everyone breathes rather than focus on specific air pollutants," the lARC's Dana Loomis said in a statement. "The results from the reviewed studies point in the same direction: the risk of developing lung cancer is significantly increased in people exposed to air pollution." In 2010, lung cancer resulting from air pollution killed 223,000 people worldwide, and there was also convincing evidence that it increases the risk of bladder cancer, according to the IARC. Air pollution is already known to raise risks for a wide range of illnesses, including respiratory and heart diseases. Air pollution is global, although the levels of it vary over space and time. Loomis said people in Asia, eastern North America, some places in Central America and Mexico, as well as North Africa have relatively high exposure. Developing countries with large populations and booming manufacturing sectors, such as China, are particularly at risk. Many cities in China, such as Beijing, frequently see smog. This week, Harbin, the capital city of Heilongjiang province, became the first Chinese city to officially suspend classes due to serious smog Many developed countries face similar problems, although to a lesser degree than most developing nations. In Europe, levels of many pollutants... Question: Why should the international community take action without further delay? - The composition and levels of air pollution vary from place to place. - More and more people in developing countries are exposed to air pollution. - Developed countries face air pollution, the level of which is higher than the safety limits. - A large number of people worldwide are exposed to air pollution.
**Answer**
A large number of people worldwide are exposed to air pollution.
