Plasma Cutters
1. Modern industry depends on the manipulation of heavy metal and alloys. We need metals to build the tools and transportation necessary for day-to-day business. The reason is simple: metals are extremely strong and durable, so they’re the logical choice for most things that need to be especially big, especially sturdy, or both.
2. The funny thing is that metal’s strength is also a weakness: because metal is so good at resisting damage, it’s very difficult to manipulate and form into specialized pieces. People can precisely cut and manipulate the metals using the plasma cutter. The plasma cutter is actually a common tool that has been around since World War II.
3. Plasma cutters are not the only devices to harness the power of plasma. Neon signs, fluorescent lighting and plasma displays, just to name a few, all rely on it to get the job done.

Определите основную идею текста.

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 речь идет о том, что плазма в разных ее формах имеет очень широкое применение:
1) плазмотроны являются очень эффективным прибором для работы с металлами, так как, имея очень высокие характеристики устойчивости к механическим воздействиям, их очень трудно обрабатывать («…because metal is so good at resisting damage, it’s very difficult to manipulate and form into specialized pieces. People can precisely cut and manipulate the metals using the plasma cutter» – фрагмент 2);
2) «холодная» плазма нашла свое применение в некоторых устройствах («Neon signs, fluorescent lighting and plasma displays, just to name a few, all rely on it to get the job done. These devices use "cool" plasma» – фрагмент 3).
Таким образом, правильный вариант ответа – «Modern industry relies on plasma as it has a lot of valuable applications» («Современная промышленность рассчитывает на плазму, так как у нее очень много применений»).

Answer 1

Modern industry relies on plasma as it has a lot of valuable applications.
