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 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 before being cooled off again when it meets a seawater-cooled metal wall, which causes moisture in the air to condense. Thus distilled water for irrigating the plants collects.

Q. Which of the following can be inferred about the importance of the seawater-moistened cardboard walls in the greenhouse design?
  • a)
    They serve as the primary source of freshwater for the greenhouse.
  • b)
    They help in maintaining the structure of the greenhouse.
  • c)
    They are crucial for cooling and humidifying the air inside the greenhouse.
  • d)
    They ensure the proper circulation of air within the greenhouse.
  • e)
    They reflect solar heat away from the greenhouse to keep it cool.
Correct answer is option 'C'. Can you explain this answer?

The passage indicates that the seawater-moistened cardboard walls cool and moisten the hot air blowing into the greenhouse and later help the air absorb more moisture before cooling it again to condense moisture. Hence, their main function is to cool and humidify the air inside the greenhouse.

Importance of Seawater-Moistened Cardboard Walls
The seawater-moistened cardboard walls are a key component of the greenhouse design, contributing significantly to its function and efficiency. Here's a detailed explanation of their importance:
1. Cooling and Humidifying Air
- The front wall, moistened by seawater, plays a vital role in cooling the hot air that enters the greenhouse.
- As the prevailing wind blows in, the moist cardboard absorbs heat from the air, cooling it down.
- This process also adds moisture to the air, creating a humid environment ideal for plant growth.
2. Enhancing Plant Growth
- The cool, humidified air that enters the greenhouse accelerates plant growth by reducing water evaporation from leaves.
- This ensures that plants can thrive in a challenging desert environment where water is typically scarce.
3. Freshwater Generation
- As the air moves through the greenhouse, it reaches the seawater-cooled metal wall at the back.
- Here, moisture in the air condenses, collecting distilled water that can be used for irrigation.
- This process is indirectly supported by the moist cardboard walls, which help maintain the humidity levels necessary for condensation.
4. Not Just Structural or Circulatory
- The cardboard walls are not primarily responsible for structural integrity or air circulation; rather, their main function revolves around cooling and humidifying the air.
- They do not reflect solar heat away, which differentiates their role from other components in the greenhouse design.
In conclusion, the seawater-moistened cardboard walls are crucial for cooling and humidifying the greenhouse air, making them indispensable for the overall function of this innovative design.

Question Description
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 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 before being cooled off again when it meets a seawater-cooled metal wall, which causes moisture in the air to condense.
