помогите ответить на вопросы... вот текст Текст: What is agriculture?

Agriculture is an important branch of economy. Economic growth of any country depends on the development of agriculture, which supplies people with food and clothing and industry with raw materials.

The world „agre" is a Latin word. It means the cultivation of fields in or-der to grow crops. Now agriculture also includes the use of land to breed farm animals.

We do not know when people began to grow crops. It was many thousands years ago. Now crop production and animal husbandry are highly developed branches of agriculture.

Life is impossible without plants. They play a highly important role in everyday life of people. Plants that are grown by farmers are known as farm crops. They are used dirutly as food for people, some are consumed by farm animals, and others are used in industry and medicine. There are many kinds of farm crops, for example wheat, sugar feet, outs, barley, and potatoes.

In order to increase crop yields and animal products our farms apply widely intensive technologies. Growing peanuts, farmers supply people with food.
