Fiber-optic communication
1. In fiber-optic communications information is transmitted by sending light through optical fibers. The light forms an electromagnetic carrier wave that is modulated to carry information. First developed in the 1970s, fiber-optic communication systems have revolutionized the telecommunications industry and have played a major role in the advent of the Information Age.
2. Optical fiber is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals. Due to much lower attenuation and interference, optical fiber has large advantages over existing copper wire in long-distance and high-demand applications. However, infrastructure development within cities was relatively difficult and time-consuming, and fiber-optic systems were complex and expensive to install and operate.
3. Due to these difficulties, fiber-optic communication systems have primarily been installed in long-distance applications, where they can be used to their full transmission capacity, offsetting the increased cost. Since 2000, the prices for fiber-optic communications have dropped considerably.

Определите, какое утверждение соответствует содержанию текста.

			Despite its obvious advantages, fiber-optic communication has mostly long-distance application.
			Fiber-optic communication is unlikely to have influenced the development of telecommunications industry.
			Fiber-optic communication differs from copper wire communication in the purpose of transmitting information.
			Yet it costs a lot of money to install and apply fiber-optic communication.

Определите основную идею текста.

			Fiber-optic communication systems are effective kind of wire communication but are not commonplace for their complexity and expensiveness.
			Optical fiber is more advantageous over existing copper wire in long-distance and high-demand applications due to its excellent operating characteristics.
			Due to the difficulties concerning complexity and high price of fiber-optic communication systems, they have only long-distance applications.
			Fiber-optic communication systems have revolutionized the telecommunications industry and have played a major role in the advent of the Information Age.

Решение:
Для того чтобы правильно выполнить задание, следует знать алгоритм обработки текстовой информации и, прочитав текст, выделить главные компоненты содержания текста, то есть определить основную идею текстовой информации.
В тексте говорится о том, что волоконно-оптическая связь:
1) является современным видом проводной электросвязи («…fiber-optic communication systems have revolutionized the telecommunications industry and have played a major role in the advent of the Information Age» – фрагмент 1);
2) использует эффективные средства для передачи информации в Интернете, оказывает услуги телефонной связи и осуществляет телевизионный прием («Optical fiber is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals» – фрагмент 2);
3) имеет очевидные преимущества перед традиционным видом связи («Due to much lower attenuation and interference, optical fiber has large advantages over existing copper wire in long-distance and high-demand applications» – фрагмент 2);
4) применяется в основном для коммуникации на дальние расстояния («…fiber-optic communication systems have primarily been installed in long-distance applications, where they can be used to their full transmission capacity…» – фрагмент 2) из-за сложности и дороговизны применения («…infrastructure development within cities was relatively difficult and time-consuming, and fiber-optic systems were complex and expensive to install and operate» – фрагмент 2).
Таким образом, правильный вариант ответа – «Fiber-optic communication systems are effective kind of wire communication but are not commonplace for their complexity and expensiveness» («Волоконно-оптические коммуникационные системы являются эффективным способом проводной связи, но не используются в большом масштабе из-за сложности и дороговизны применения»).
