Final answer:
Concrete is the best option for an outdoor garbage container surface as it's easy to clean and durable. Asphalt is also acceptable, while grass and gravel are less ideal. It is crucial to avoid using oceans as dumping grounds and to follow local waste disposal guidelines.
Step-by-step explanation:
A good surface for keeping outdoor garbage containers is important to maintain sanitation and ease of cleanup. Of the options provided, Option 1: Concrete would make a good place to keep outdoor garbage containers. Concrete is hard, easy to clean, doesn't retain odors, and prevents animals from digging underneath. Option 4: Asphalt is similar to concrete in these aspects and could also serve as a suitable surface. Option 2: Grass and Option 3: Gravel are less ideal as they are harder to clean, can allow liquids to seep into the ground, and may enable animals to scatter trash more easily.
It is also vital to remember not to use the ocean as a dumping ground. Garbage in the ocean creates severe environmental issues, including harm to wildlife. Instead, we should follow local recycling and waste disposal regulations to minimize pollution.
