How is the effectiveness of plasma used in industry?

Для того чтобы правильно выполнить задание, следует знать алгоритм обработки текстовой информации при изучающем чтении, уметь анализировать получаемую информацию и, читая текст, находить ответ на поставленный вопрос.
Правильный ответ на вопрос «Как используется эффективность плазмы в промышленности?» – «Plasma cutter is irreplaceable for manipulations with metals and “cool” plasma can be used for illumination» («Плазмотрон незаменим при манипуляциях с металлами, а “холодная” плазма может использоваться для освещения»), так как согласно тексту: «People can precisely cut and manipulate the metals using the plasma cutter» («Люди могут резать металл с высокой точностью и манипулировать с ними, используя плазмотрон» – фрагмент 2) и «Neon signs, fluorescent lighting and plasma displays… use "cool" plasma» («Неоновые вывески, флуоресцентное освещение и плазменные панели… используют “холодную” плазму» – фрагмент 3).

Answer 1

Plasma cutter is irreplaceable for manipulations with metals and “cool” plasma can be used for illumination.
