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:
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.

Lời giải:
Báo saiChúng ta có thể suy ra từ bài đọc rằng đất nung có những lợi ích nào sau đây?
Nó không bị vỡ suốt quá trình nung
Nó rẻ hơn các vật liệu có sẵn khác
Bề mặt của nó sáng bóng lâu
Nó có thể được sử dụng cho nhiều mục đích
Dẫn chứng: “The broad utility of terra-cotta was such that workers in clay could generally afford to confine themselves to either decorated housewares like cooking pots and jars or building materials like roof tiles and drainpipes” (Ứng dụng của đất nung là rất rộng nên các công nhân có thể tự giới hạn mình với các đồ dùng gia đình trang trí như nồi nấu ăn và chum dự trữ hoặc vật liệu xây dựng như ngói và ống thoát nước.)
