The correct response is:
Oil and natural gas are chemically broken down into small compounds that combine to form plastic.
This accurately describes the process of creating plastic from petrochemical sources.

The correct response is:
a chain of repeating compounds found in both natural and synthetic materials.
This definition accurately describes a polymer, which consists of long chains of repeating molecules (monomers) and can be found in both natural substances (like proteins and cellulose) and synthetic materials (like plastics).

It needs to go through a chemical reaction.
The correct response is:
It needs to go through a chemical reaction.
This is because synthetic materials are typically created through chemical processes that transform natural resources into new compounds.
