1. The form of energy that illuminates our world is called light. It usually comes from hot objects, like the sun or fire, but it is also produced by electricity and some chemical reactions. Light is the only part of the electromagnetic spectrum (which includes microwaves, ultraviolet rays, and X-rays) that is invisible to the human eye. It travels at 186,000 miles (300,000 km) per second, and nothing can travel faster. Like other forms of energy, light travels in waves, but it can also travel in packets of energy called quanta. This enables it to travel through a vacuum.
2. Light rays are reflected when they hit a shiny or silvered surface, such as a still pool of water or a mirror. Reflection involves two light rays: the incoming ray and the reflected ray which bounces off the reflecting surface. The two rays are at identical angles to the reflecting surface on either side of an imaginary line.
3. Refraction is a property of all types of energy that travel in waves, including light. Light waves normally travel in straight lines, but when they pass from one transparent material to another, they usually refract, or bend. Refraction occurs because light travels at different speeds in different materials. As light from a material with a low density, such as air, enters a material with a high density, such as water, its speed is reduced. This causes it to bend (except when it enters a material at a right angle).

Чтобы правильно выполнить задание, следует знать алгоритм обработки текстовой информации и, прочитав текст, завершить утверждение согласно содержанию текста.
Утверждение «Unlike all other kinds of electromagnetic radiation light…» («В отличие от остальных типов электромагнитного излучения свет…») следует закончить вариантом ответа «is able to be seen» («можно увидеть»), так как именно это утверждение соответствует содержанию текста.
Согласно тексту: «Light is the only part of the electromagnetic spectrum… that is visible to the human eye» («Свет – это единственная часть электромагнитного спектра (электромагнитный спектр – это спектр электромагнитного излучения), который воспринимается человеческим глазом») (фрагмент 1).
