Read the article and select the best answer. 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 _ . Options: A: growing genetic foods will make farmers richer B: people will eat more genetic foods in the future C: using fewer chemicals could make the food tastier D: there could be unknown dangers about genetic foods

Read the article and select the best answer. Article: Light travels at a speed which is about a million times faster than the speed of sound. You can get some idea of this difference by watching the start of a race. If you stand some distance away from the starter, you can see smoke from his gun before the sound reaches your ears. This great speed of light produces some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays left the moon 1.3 seconds before they reached you. The nearest star is so far away that the light that you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km. per minute. In some cases, the light from one of tonight's stars had started on its journey to you before you were born. Thus, if we want to be honest, we can't say, "The stars are shining tonight." We have to say instead, "The stars look pretty. They were shining four years ago, but their light has only just reached the earth." Question: Sunlight obviously _ than the light of the moon. Options: A: has to travel a greater distance B: moves less quickly C: travels much more quickly D: is less powerful
(Answer)
A
