Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Recycling and reusing materials is a sustainable practice for managing construction waste as it reduces the amount of waste sent to landfills, conserves natural resources, and promotes circular economy principles.

Multiple choice

Which of the following is a good way to reduce food waste?

  1. Composting food scraps

  2. Freezing leftovers

  3. Eating ugly produce

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Composting food scraps, freezing leftovers, and eating ugly produce are all good ways to reduce food waste. Composting helps to recycle nutrients back into the soil, freezing leftovers helps to preserve food so that it can be eaten later, and eating ugly produce helps to reduce the amount of food that is wasted because it does not meet cosmetic standards.

Multiple choice
