Composting is a great way to reduce waste and create nutrient-rich soil. Here's how it works:
Step 1: Collect organic waste like fruit and vegetable scraps, coffee grounds, and leaves.
Step 2: Find a suitable spot for your compost bin, preferably a shady area.
Step 3: Start layering your organic waste, alternating 'greens' (nitrogen-rich) and 'browns' (carbon-rich).
Step 4: Keep the compost moist, like a wrung-out sponge, and turn it regularly to aerate it.
Step 5: Wait for the materials to break down, which can take a few months to a year, until you have dark, crumbly compost.
What is the main purpose of 'turning the compost regularly' in Step 4?
A) To make it look tidy.
B) To add more organic waste.
C) To aerate it.
D) To keep it moist.
