Read the passage carefully, then choose the correct answer.

Coal, oil, and natural gas supply modern civilization with most of irs power. However, not only are supplies of these fuels limited, but they are a major source of pollution. Therefore, it's important to improve, explore and develop such alternative energy sources as nuclear, water, solar and wind power. Each of these alternatives, however, has advantages and disadvantages.

Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they create the difficult problenı of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities locnted far from moving water.Wind power is a pollution-free source renewable energy but it cannot be used many parts of the world where there is insufficient wind. Solar power renewable, it does not cause pollution and it does not add the earth's heat load. However, it ia dilficult to coilect and store. Solar power also requir eensive equipnent

Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resoucs wll ensure supplies of clean, affordable energy for humanity's future.

Fifty years ago hydroelectric power provided one third of the electricity used in theUnited States, but today it supplies only four percent. The oceans are another potential source of energy.

III. Read the following passage. Decide if the statements from 13 to 16 are True or
False, and choose the correct answers (A, B, C or D) for questions 17 and 18. (1.5 pts)
Plastics is the term commonly used to describe a wide range of synthetic or semi-
synthetic materials that are used in a huge and growing range of applications. Everywhere
you look, you will find plastics. We use plastic products to help make our lives cleaner,
easier, safer and more enjoyable. We find plastics in the clothes we wear, the houses we live
in, and the cars we travel in. The toys we play with, the televisions we watch, the computers
we use and the DVDs we watch all contain plastics.
Plastics are organic materials, just like wood, paper or wool. The raw materials used to
produce plastics are natural products such as cellulose, coal, natural gas, salt and, of course,
crude oil. Plastics have become the modern material of choice because they make it possible
to balance today’s needs with environmental concerns.
The term “plastic” is derived from the Greek word “plastikos”, meaning fit for moulding.
This refers to the material’s malleability, or plasticity during manufacture, which allows it to be
cast, pressed, or extruded into a variety of shapes - such as films, fibres, plates, tubes,
bottles, boxes, and much more.

(Adapted from https://www.plasticseurope.org)

13. Plastics is the term describing a wide range of synthetic materials only.
14. We find plastics everywhere except the clothes we wear.
15. Cellulose, coal, natural gas, salt and crude oil can be used to produce plastics.
16. The word “plastic” in English has its origin in Greek.
17. What is the passage mainly about?
A. Synthetic or semi-synthetic materials
B. Plastic products in everyday life
C. General understanding of plastics
D. Raw materials used to produce plastics
18. What allows plastic to be cast, pressed, or extruded into a variety of shapes?
A. Its high boiling point B. Its toughness
C. Its cellulose origin D. Its malleability
