(2) After a few months of such care, the waste becomes a dark, crumbly material that can be returned to the soil. (3) Dry leaves supply the carbon, while fruit peels and vegetable scraps supply the nitrogen. (4) The process relies on bacteria and fungi that break down organic matter. (5) Composting turns kitchen and garden waste into a rich natural fertilizer. (6) The pile must also be turned regularly so that air can reach its center.

5-1-4-3-6-2
5-4-1-3-2-6

Answer

A. 5-4-1-3-6-2

Solution

The correct order is 5-4-1-3-6-2. Each sentence picks up an idea from the one before it: Composting turns kitchen and garden waste into a rich natural fertilizer. The process relies on bacteria and fungi that break down organic matter. To work well, these organisms need a balance of moisture, air, and materials rich in carbon and nitrogen. Dry leaves supply the carbon, while fruit peels and vegetable scraps supply the nitrogen. The pile must also be turned regularly so that air can reach its center. After a few months of such care, the waste becomes a dark, crumbly material that can be returned to the soil. Each wrong choice swaps just one pair of neighboring sentences, which breaks one of these links.
