Read the passage and answer the multiple-choice questions.
In 1863, the French writer Ponton D'Amecourt was the first person to create the word "helicopter" from the two words "helico" for spiral and "pter" for wings. The very first helicopter was invented by Paul Cornu in 1907, but it was not successful. French inventor, Etienne Oehmichen built and flew a helicopter one kilometer in 1924.
However, Igor Sikorsky is considered to be the father of helicopters not because he invented the first. He is called that because he invented the first successful helicopter, upon which further design were based.

By 1940, Igor Sikorsky's successful VS-300 had become the model for all modern helicopters of today. He also designed and built the first military helicopter.
Igor Sikorsky's helicopters had the control to fly safely forwards and backwards, up and down, and sideways. In 1958, Igor Sikorsky's company made the world's first helicopter that could land and take off from water. It could also float on the water.

Research has show that over half the children in Britain who take their own lunches to school do not eat properly in the middle on the day. In Britain, schools have to provide meals at lunchtime. Children can chose to bring their own food or have lunch at the school canteen.
One shocking finding of this research is that school meals are many healthier than lunches prepared by parents. There are strict standards for the preparation of school meals, which have to include one piece of fruit and one of vegetables, as well like meat, a dairy item and starchy food like bread or pasta. Lunchboxes examined by researchers contained sweet drinks, crisps and chocolate bar. Children consume twice as much sugar as they should at lunchtime.
The research will provides a better understanding of why the percentage of overweight students in Britain have increased in the last decade. Unfortunately, the government cannot criticize parents, but it can remind them of the nutritional value of milk, fruit and vegetables. Small changes in their children’s diet can affect their future healthy. Children can easy develop bad eating habits at this age, and parents are the only ones who can prevent it.

Living in the country has both advantages and disadvantages. There are certainly many advantages to live in the country. First, you can enjoy peace and quietness. The air in the countryside is often fresher than in the city. Second, people tend to be friendlier. They live not very far from the others; they know each other very well. If someone needs help, they are ready to help anytime. Moreover, there is less traffic, so it is safer for young children. However, there are certain disadvantages to life outside the city. First, because there are fewer people, you are likely to have few friends. In addition, entertainment is difficult to find, particularly in the evening. Moreover, education seems to be less developed than it in the city. Therefore, the children are less accessed to the modern technology. On the whole, it is often the best for those who are retired or who have young children to live in the country. In contrast, young people who have a career are better provided in the city.
