Article: Today there are 7 billion people on the earth.By the year 2050 there may be 9.0 billion.We will have a lot more people to feed.We need more food. One way to produce more food is by growing stronger plants.For thousands of years,farmers have made plants better.Every season,they pick the best plants for the next season.It works very slowly.Since1983 scientists have been able to change plants more quickly by changing their genetic material. 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. They may feed people,then hurt them or their children later.But both rich and poor countries are very interested in their use,and they are not going to die.In 2050 we may think differently about them.

Ques:Read the following article and select the best answer. Article: We are always using body language in our daily life. When we have a conversation with someone, we may be using more body language than words. However, the same body language may mean different things in different countries. That's why people sometimes do not understand each other correctly. Pointing to one part of the body can mean differently in different cultures. For example, in the USA people point to their heads when they think someone is clever. However, in Europe it means 'He or she is stupid or something is wrong with his or her head'. In our Chinese culture, nodding our head up and down means 'yes' and shaking our head from side to side means 'no'. However, in parts of India, Greece and Turkey, it means just the opposite . In England or the USA, when you raise your hand and make a circle with the thumb and the second finger, it means 'You're all right or Everything is OK'. However, if we do this in France or Belgium, it means 'You're worth zero'. In Greece or Turkey, we should not make this gesture . Or we are thought to be very rude. The meaning of gestures can also change over time. In the 1960s, the V sign meant 'peace'. However, during World War II, it meant 'victory'. In Greece, it is a very insulting sign. Though the meaning of body language is different, there are some expressions having the same meaning throughout the world, such as smiling and crying. Question: V sign meant _ about fifty years ago. - victory - killing - festival - peace

Ans:peace

Ques:Read the following article and select the best answer. Article: When a computer works on a group of programs,it can get very hot.Cooling the computer can cost a lot.So some scientists wonder what would happen if the heat from the computer could beused. Large Internet companies such as Google and Microsoft have thousands of computers.As these computers deal with information,they produce lots of heat,so they need huge cooling systems .These systems send the heat in to the air. A company in Holland thinks paying to make the computers work and then paying again to cool them are a waste of energy.So the company developed a special device-thee-Radiator. Boaz Leupe,head of the company,says that e-Radiator works as a heating system and saves money.He explains that the energy is used twice-once to heat the home and once to cool the computer and that the users don't have to pay to cool their computers. Five homeowners in Holland are testing the heating system in their homes. "We pay for the computer using,so,in that way,homeowners get heating for free,"Boaz says.Jan Visser is one of the homeowners."If you use the computer more,the e-Radiator producers more heat,"he says,"It cannot provide enough heat if you don't use your computer often."But he is ready to try it.It's a great help for his family. The company says e-Radiators produce heat temperatures of up to 55degC.It says the system could save its users about 440 a year. Question: Before the e-Radiator appears,usually the heat of a computer _ . - is sent into the air - helps the five homeowners - is used twice - makes the computer work better

Ans:
is sent into the air
