Câu hỏi: 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 from 30 to 34.
Because the low latitudes of the Earth, the areas near the equator, receive more heat than the latitudes near the poles, and because the nature of heat is to expand and move, heat is transported from the tropics to the middle and high latitudes. Some of this heat is moved by winds and some by ocean currents, and some gets stored in the atmosphere in the form of latent heat. The term "latent heat" refers to the energy that has to be used to convert liquid water to water vapor. We know that if we warm a pan of water on a stove, it will evaporate, or turn into vapor, faster than if it is allowed to sit at room temperature. We also know that if we hang wet clothes outside in the summertime, they will dry faster than in winter, when the temperature is lower. The energy used in both cases to change liquid water to water vapor is supplied by heat - supplied by the stove in the first case and by the Sun in the latter case. This energy is not lost. It is stored as vapor in the atmosphere as latent heat. Eventually, the water stored as vapor in the atmosphere will condense to liquid again, and the energy will be released to the atmosphere.
In the atmosphere, a large portion of the Sun's incoming energy is used to evaporate water, primarily in the tropical oceans. Scientists have tried to quantify this proportion of the Sun's energy. By analyzing temperature, water vapor, and wind data around the globe, they have estimated the quantity to be about 90 watts per square meter, or nearly 30 percent of the Sun's energy. Once this latent heat is stored within the atmosphere, it can be transported, primarily to higher latitudes, by prevailing, large - scale winds. Or it can be transported vertically to higher levels in the atmosphere, where it forms clouds and subsequent storms, which then release the energy back to the atmosphere.
Why does the author mention "the stove" in the passage?
A. To describe the heat of the Sun.
B. To illustrate how water vapor is stored.
C. To show how energy is stored.
D. To give an example of a heat source

Tại sao tác giả đề cập đến "the stove-cái bếp" trong bài đọc?
A. Để mô tả nhiệt của mặt trời
B. Để minh họa hơi nước được lưu trữ như thế nào
C. Để chỉ ra năng lượng được lưu trữ như thế nào
D. Để đưa ra một ví dụ của nguồn nhiệt
Dẫn chứng: We know that if we warm a pan of water on a stove, it will evaporate, or turn into vapor, faster than if it is allowed to sit at room temperature. We also know that if we hang wet clothes outside in the summertime, they will dry faster than in winter, when the temperature is lower. The energy used in both cases to change liquid water to water vapor is supplied by heat - supplied by the stove in the first case and by the Sun in the latter case. (Chúng ta biết rằng nếu chúng ta đun một ấm nước trên bếp thì nó sẽ bay hơi, hoặc biến thành hơi nước nhanh hơn nếu nó được để ở nhiệt độ phòng. Chúng ta cũng biết rằng nếu chúng ta treo quần áo ướt bên ngoài vào mùa hè thì chúng sẽ khô nhanh hơn vào mùa đông, khi nhiệt độ thấp hơn. Năng lượng được sử dụng trong cả hai trường hợp để biến đổi nước lỏng thành hơi nước được cung cấp bởi nhiệt - được cung cấp bởi cái bếp trong trường hợp đầu tiên và bởi mặt trời trong trường hợp sau.)
