🔍 Key Concepts

• Ventilation and air circulation in refrigerated or air-conditioned cargo spaces • How moisture, mold, and slime form in closed, damp environments • Relationship between air circulation and temperature/moisture uniformity

💭 Think About

• Think about what happens in a closed, cool, damp room with little or no air movement. What tends to grow or accumulate over time? • Consider which option describes an effect that would help preserve cargo quality rather than harm it. • Ask yourself: does proper circulation usually increase or decrease moisture and biological growth?

✅ Before You Answer

• Which choice best reflects hygienic/clean conditions in a cargo space? • Which options describe effects that would actually be unfavorable for cargo preservation? • Verify which effect is most directly tied to moving air preventing damp, stagnant pockets in the space.
