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, which of the following is true about solar power?

A. There is very little of it available in Iceland.

B. It is being used in 100, 000 private homes worldwide.

C. It is 6,000 times more powerful than energy from fossil fuels.

D. There is enough of it to far exceed the energy needs of the world.

Answer 1

[Dương Hoàn Anh]

Đáp án D.

Key words: true, solar power

Clue: 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: Năng lượng mặt trời, đến trái đất qua ánh sáng mặt trời, dồi dào đến mức nó có thể đáp ứng gấp 6000 lần nhu cầu tiêu thụ năng lượng trên toàn thế giới.

Vậy đáp án chính xác là D. There is enough of it to far exceed the energy needs of the world: Lượng (năng lượng mặt trời) vượt xa nhu cầu sử dụng năng lượng trên toàn thế giới

Các đáp án còn lại là sai:

A. There is very little of it available in Iceland: Có rất ít (năng lượng mặt trời) ở Iceland

B. It is being used in 100,000 private homes worldwide: Nó được sử dụng ở 100.000 hộ gia đình trên toàn thế giới

C. It is 6,000 times more powerful than energy from fossil fuels: Nó mạnh hơn năng lượng hóa thạch 6.000 lần
