Question

Which of the following is a primary function of a moldboard plow in soil tillage?

Answer 1

Key Concept: Fresh produce keeps respiring after harvest, and respiration rate drives how fast it spoils or ripens.

Why it's correct: Controlled atmosphere storage adjusts oxygen, CO₂, and nitrogen levels specifically to slow respiration, extending shelf life and delaying ripening/senescence.

Why others fail: Increasing humidity and enhancing color are secondary at best, and promoting ripening is the OPPOSITE of CA storage's actual goal, which is to delay it.
