Answer:

Which thing is most likely to have stayed the same?

When things are buried in wet ground, they are subjected to various environmental conditions such as moisture, temperature, and microbial activity. These conditions can cause different materials to decay or degrade over time. Therefore, the material that is most likely to have stayed the same is the one that is resistant to decay or degradation.

Option 'D' - A plastic glass is the most likely material to have stayed the same. This is because plastic is a synthetic material that is designed to be durable and resistant to environmental degradation. Unlike natural materials such as eggshells, paper cups, and vegetable peels, plastic does not decompose easily and can remain intact for a long time.

Explanation:

Eggshells:

Eggshells are made up of calcium carbonate, which is a natural material that can easily decompose in wet soil. Microbial activity in the soil can break down the eggshell into smaller pieces, and the calcium carbonate can react with the soil's acidic components, resulting in the eggshell's decomposition. Therefore, an eggshell is not likely to stay the same after being buried in wet ground for several years.

Paper cups:

Paper cups are made up of wood pulp, which is a natural material that can easily decompose in wet soil. Microbial activity in the soil can break down the paper cup into smaller pieces, and the cellulose in the wood pulp can react with the soil's acidic components, resulting in the paper cup's decomposition. Therefore, a paper cup is not likely to stay the same after being buried in wet ground for several years.

Vegetable peels:

Vegetable peels are made up of organic matter, which is a natural material that can easily decompose in wet soil. Microbial activity in the soil can break down the vegetable peel into smaller pieces, and the organic matter can react with the soil's acidic components, resulting in the vegetable peel's decomposition. Therefore, a vegetable peel is not likely to stay the same after being buried in wet ground for several years.

Plastic glasses:

Plastic glasses are made up of synthetic polymers, which are materials that are designed to be durable and resistant to environmental degradation. Plastic glasses do not decompose easily, and microbial activity in the soil cannot break down the plastic into smaller pieces. Therefore, a plastic glass is most likely to stay the same after being buried in wet ground for several years.

Conclusion:

In summary, a plastic glass is the material that is most likely to have stayed the same after being buried in wet ground for several years. This is because plastic is a synthetic material that is designed to be durable and resistant to environmental degradation. Unlike natural materials such as eggshells, paper cups, and vegetable peels, plastic does not decompose easily and can remain intact for a long time.
