Yes, I am sure. Here is the breakdown of the filled-in sentence:
- "Plastics are considered to be polymers because they are made of long chains of repeating small molecules." (Polymers are large molecules made up of repeated subunits called monomers.)
- "Plastics are made by humans, so they are categorized as synthetic materials." (Synthetic materials are man-made, while natural materials are found in nature.)
- "Even so, manufacturers must use monomers to produce plastics." (Monomers are the smaller molecules that link together to form polymers.)
