natural, synthetic, monomers, polymers, biodegradable
Plastics are considered to be polymers because they are made of long chains of repeating small molecules. Plastics are made by humans, so they are categorized as synthetic materials. Even so, manufacturers must use monomers materials to produce plastics.
Read the following two passages. Then drag each conclusion statement into the box for the article that provides details to support that conclusion.
Hooray for Plastic! (Passage 1): Many types of plastics are lightweight, strong, and resistant to breakage. In some cities, plastic recycling centers are available for the public. Many types of plastics are available for consumer uses.
Stop Using Plastic! (Passage 2): Some plastics contain harmful chemicals like BPA. Plastics usually don't degrade in a reasonable time, and recycling is not reliable. In order to produce plastics, fossil fuels (like petroleum) have to be retrieved using drilling operations.

Plastics are considered to be [polymers] because they are made of long chains of repeating small molecules. Plastics are made by humans, so they are categorized as [synthetic] materials. Even so, manufacturers must use [monomers] to produce plastics.
To answer this question, we need to understand the definitions of the given terms and their significance in relation to plastics.
1. Plastics are considered to be _________________ because they are made of long chains of repeating small molecules.
To fill this blank, we need to identify the term that describes the composition of plastics. Plastics are made up of long chains of repeating units known as monomers, which combine to form polymers. Therefore, the correct term to fill this blank is "polymers."
2. Plastics are made by humans, so they are categorized as _________________ materials.
To fill this blank, we need to identify the term that categorizes materials produced by humans. Plastics are human-made and not naturally occurring, so they are classified as "synthetic" materials.
3. Even so, manufacturers must use _________________ materials to produce plastics.
To fill this blank, we need to identify the term that describes the materials used by manufacturers to produce plastics. While plastics themselves are synthetic, manufacturers often incorporate natural resources or materials called "monomers" to create them.
So, the correct fill-ins for the blanks are:
1. Plastics are considered to be __polymers__ because they are made of long chains of repeating small molecules.
2. Plastics are made by humans, so they are categorized as __synthetic__ materials.
3. Even so, manufacturers must use __monomers__ materials to produce plastics.
