Foods from plants grown in this way are called genetically modified foods ,or GM foods. By changing the genetic material of a plant,it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases:a kind of rice is being prepared,for example,which stops people from becoming blind.Rich countries produce GM foods because they are easy to grow and they bring in more money.Poor countries are interested in them because they help produce more food. GM plants are not natural.No one knows how good or bad they are.Making GM foods is only one way of feeding people in 2050.But there are strong feelings against them,because they are unnatural.

Question: Read the article and select the best answer. Article: We can make mistakes at any age. Some mistakes we make are about money. But most mistakes are about people. Why do we go wrong about our friends? Sometimes people hide their real meanings when they say something. And if we don't really listen, we miss the feeling behind the words. Suppose someone tells you, "You're a lucky dog." That's being friendly. But "lucky dog"? There's a bit of envy in those words. Maybe he doesn't see himself. But "lucky dog" puts you down a little. He may mean you don't deserve your luck. How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking. Do his words fit the way he looks? Do his words agree with the tone of voice? His posture ? The look in his eyes? Stop and think. If you spend the minute thinking about the real meaning behind one's words, it may save another mistake. Question: According to the passage, the reason why we go wrong about our friends is that _ . Options: A: we fail to listen carefully when they talk B: we become angry when we realize what they really mean C: they sometimes said one thing but meant another D: we never believe what people say
