Which term describes polypropylene?

Which term describes polypropylene?

• A. Synthetic
• B. Elastic
• C. Durable
• D. Insulating

Answer: (A)

Polypropylene is a synthetic material. It is a man-made plastic formed by polymerizing propylene monomers derived from petroleum. Because it’s produced through chemical manufacturing rather than occurring naturally, the word that best describes it is synthetic. Other terms refer to how it behaves or is used—elastic describes stretchiness (not a defining feature, as polypropylene is relatively stiff), durable points to its toughness (a beneficial property, not its origin), and insulating notes a use or capability (it can insulate in some roles, but that doesn’t classify the material itself).
