Question

[Lê Quỳnh Anh]

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

        In this era of increased global warming and diminishing fossil fuel supplies, we must begin to put a greater priority on harnessing alternative energy sources. Fortunately, there are a number of readily available, renewable resources that are both cost- effective and earth - friendly. Two such resources are solar power and geothermal power.

        Solar energy, which reaches the earth through sunlight, is so abundant that it could meet the needs of worldwide energy consumption 6,000 times over. And solar energy is easily harnessed through the use of photovoltaic cells that convert sunlight to electricity. In the US alone, more than 100, 000 homes are equipped with solar electric systems in the form of solar panels or solar roof tiles. And in other parts of the world, including many developing countries, the use of solar system is growing steadily.

       Another alternative energy source, which is abundant in specific geographical areas, is geothermal power, which creates energy by tapping heat from below the surface of the earth. Hot water and steam that are trapped in underground pools are pumped to the surface and used to run a generator, which produces electricity. Geothermal energy is 50,000 times more abundant than the entire known supply of fossil fuel resources and as with solar power, the technology needed to utilize geothermal energy is fairly simple. A prime example of effective geothermal use in Iceland, a region of high geothermal activity where there are over 80 percent of private homes, are heated by geothermal power.

       Solar and geothermal energy are just two of promising renewable alternatives to conventional energy sources. The time is long overdue to invest in the development and use of alternative energy on global scale.

According to the passage, how is solar energy production similar to geothermal energy production?

A. They both require the use of a generator.

B. They both use heat from the earth’s surface.

C. They both require fairly simple technology.

D. They are both conventional and costly.

Answer 1

[Dương Hoàn Anh]

Đáp án C.

Key words: solar energy production, similar, geothermal energy production

Clue: Geothermal energy is 50,000 times more abundant than the entire known supply of fossil fuel resources and as with solar power, the technology needed to utilize geothermal energy is fairly simple: Năng lượng địa nhiệt phong phú hơn gấp 50.000 lần so với toàn bộ nguồn cung cấp nhiên liệu hóa thạch được biết đến và như với năng lượng mặt trời, công nghệ cần thiết để sử dụng năng lượng địa nhiệt là khả đơn giản. Vậy đáp án chính xác là C. They both require fairly simple technology: Chúng đều cần công nghệ khá đơn giản

Các đáp án còn lại là sai:

A. They both require the use of a generator: Chúng đều cần sử dụng máy phát điện

B. They both use heat from the earth’s surface: Chúng đều sử dụng nhiệt từ bề mặt trái đất

D. They are both conventional and costly: Chúng đều là nguồn năng lượng truyền thống và đắt đỏ
