LASER
1. Laser, one of the most sophisticated inventions of man, produces an intensive light beam of a very pure single colour. One of the mankind´s oldest dreams of technology to provide a light beam intensive enough to vaporize the hardest and most heat-resistant materials came true. Laser can indeed make lead run like water, or, when focused, it can vaporize any substance on earth. Laser is becoming one of the main technological tools nowadays.
2. The applications of laser in industry and science are so many and so varied as to suggest magic1. Scientists in many countries are working at a very interesting problem: combining the two big technological discoveries of the second half of the 20-th century: laser and thermonuclear reaction, to produce a practically inexhaustible source of energy. There also exists an idea to use laser for solving the problem of controlled thermonuclear reaction.
3. The laser´s most important potential may be its use in communication. The intensity of a laser can be rapidly changed to encode very complex signals. One laser beam, vibrating a billion times faster than ordinary radio waves, could transmit the entire text of the Encyclopedia Britannica in just a fraction of a second.
4. Besides, there are projects to use lasers for long distance communication and for transmission of energy to space stations, to the surface of the Moon or to planets in the solar system. Projects have also been suggested to place lasers aboard Earth satellites nearer to the Sun in order to transform the solar radiation into laser beams. There is no doubt2 that in time3 these projects will be realized and the laser beam will begin operating in outer space as well.

VII. Прочитайте вопрос к тексту. Из приведенных вариантов ответа укажите номер предложения, содержащего правильный ответ на поставленный вопрос:
What is the aim of placing lasers aboard Earth satellites nearer to the Sun?
1. To use laser for solving the problem of controlled thermonuclear reaction.
2. To transform the solar radiation into laser
