For hot desert locations with access to seawater, a new greenhouse design generates freshwater and cool air. Oriented to the prevailing wind, the front wall of perforated cardboard, moistened and cooled by a trickle of seawater pumped in, cools and moistens hot air blowing in. This cool, humidified air accelerates plant growth; little water evaporates from leaves. Though greenhouses normally capture the heat of sunlight, a double-layered roof, the inner layer coated to reflect infrared light outward, allows visible sunlight in but traps solar heat between the two layers. This heated air, drawn down from the roof, then mixes with the greenhouse air as it reaches a second seawater-moistened cardboard wall at the back of the greenhouse. There the air absorbs more moisture, which then condenses on a metal wall cooled by seawater, and thus distilled water for irrigating the plants collects. [br] It can be inferred that the greenhouse roof is designed to allow for which of the following?
选项
A、The avoidance of intense solar heat inside the greenhouse
B、The entry of sunlight into the greenhouse to make the plants grow
C、The mixture of heated air with greenhouse air to enhance the collection of moisture
答案
A
解析
All three choices are correct. This question asks the reader which of the three effects listed in the answer choices are intended as part of the design of the greenhouse roof.
Choice A is correct: the purpose of the double-layered roof is to trap solar heat before it gets inside the greenhouse proper.
Choice B is correct: the coating on the inner layer of the roof allows visible sunlight into the greenhouse.
Choice C is correct: the last two sentences of the passage describe how heated air from the roof is drawn down to mix with greenhouse air, resulting in the collection of distilled water for irrigation purposes.
