Q: Read the following article and answer the question. Article: How do you pay for things? Do you usually use cash , or do you like to pay by credit card ? If you are like a lot of people, you probably have at least one credit card. Also, you might use it more often than you probably should. Credit cards first became popular in the 1920s, At that time, businesses, such as hotels and companies, gave credit cards to their best customers . Unlike today's credit cards, customers could only use these cards at the Store or business that gave out the card. Customers had to pay for things in full. They couldn't pay for something a little at a time. In 1950, a businessman named McNamara started a credit card company -- Diners Club. Unlike earlier credit cards, this card could be used by customers at many restaurants. Customers liked the card because they didn't have to carry a lot of cash with them. Restaurant owners liked the card, too. Why? They found out that customers usually spent more money when they could pay by credit card. In its first year of business, Diners Club _ 200 cards, The customers who got the cards from the Diners Club could use them at 27 different restaurants. Today, Diners Club has about 8 million customers, and they can use their cards in over 7. 6 million businesses in more than 200 countries. Question: This passage is mainly about _ . Answer:

Q: Read the following article and answer the question. Article: Emma and Hannah are 13-year-old school girls from Minnesota, USA. They are good at making new things and both of them are also good at sales. They are selling charms made out of bottle caps. The girls came up with the idea last summer when they saw charms were popular with kids. They talked with their parents about the idea. Since then they have sold enough charms to buy a bike for Hannah. The girls collect bottle caps and then clean them. They find some interesting pictures on the Internet or on paper, and then glue them onto the inside of the caps. There are different kinds of pictures. "Peace signs are popular with girls, and single-letter charms are popular with boys whose names start with those letters," Emma and Hannah said. Now, charms can be found everywhere at Dakota Hills Middle School in Eagan. "Students put charms on purses, backpacks, and their lunchboxes," said Emma. Emma and Hannah also have a shop on the Internet. They hope they can sell their charms to more kids. They're thinking about selling their charms at the Eagan Market Festival next summer. Their business is not only for getting money. At their Valentine's sale, 20% of the income went to charity. Question: Which of the following may NOT be on the charms? Answer:

Problem:OPTIONS:
- growing genetic foods will make farmers richer
- people will eat more genetic foods in the future
- using fewer chemicals could make the food tastier
- there could be unknown dangers about genetic foods

Read the following article and answer the question. Article: Sugar--free beets that still taste sweet, tastier tomatoes and brighter-colored fruits and vegetables that stay ripe longer are all foods that are being grown now. How can they carry traits, such as being tastier, brighter, and riper? They are genetically engineered. Genetic engineering is like making a change in a recipe. For example, when you make cakes, you mix together all of the usual ingredients. If you add an extra ingredient, like salt, the cakes will taste differently. Genes are ingredients in the recipe for life. They carry the traits of living things. Your genes dictate what color hair and eyes you'll have, how tall you'll be, as well as many other traits. Genes carry traits for plants, too. By adding genes to a plant, you can sometimes create new traits. For example, adding a certain gene to a potato plant can make the potato plant distasteful to bugs . This makes some farmers happy because they don't have to use chemicals to keep bugs away from their plants. It sounds great, but some people are opposed to the idea of food that is genetically engineered. Ronnie Cummins, from the Campaign for Food Safety, is against it. He says that one of the major concerns is allergies . Supermarkets don't always label foods that are genetically engineered. A customer could unknowingly buy food that has an added gene from another plant that he or she is allergic to. It could be dangerous. Gary Burton from Monsanto, a seed company that engineers food, disagrees. He says his company tests for allergies. Burton believes that genetic engineering is a valuable tool for making better food. The technology can help farmers use less insecticide and grow healthier crops. Burton thinks there are many advantages. But Cummins says that we just don't know what will happen in the future if we keep adding genes to foods. We could mistakenly create a monster. People have different opinions about genetic engineering. One side supports it and thinks it will only help us. The other side is opposed to playing with nature and fears... Question: It can be inferred that _ . Answer:
****
A:
there could be unknown dangers about genetic foods
