Step 1: Understanding the Concept:
This is a green skills question. It asks what a responsible student should do about a waste problem at school. The best response solves the cause, not just the symptom.
Step 2: The problem:
The bin is full beyond capacity every day. This means too much waste is produced. A lasting fix must cut the amount of waste.
Step 3: Check option (A) Throw garbage on the floor:
This spoils the class and spreads dirt. It is irresponsible. So (A) is wrong.
Step 4: Check option (B) Talk to friends only:
Talking is fine, but it takes no action. The bin stays full. So (B) is weak.
Step 5: Check option (C) Talk to the teacher:
This reports the issue, which is useful. But it hands the problem to someone else and gives no solution.
Step 6: Check option (D) Suggest ways to reduce garbage:
This tackles the cause. Ideas such as separate bins, reuse of paper and less packaging cut the waste itself. It shows initiative. So (D) is best.
Final Answer:
The best action is to suggest ways to reduce the garbage collected. This is option (D).
