The method used to make polypropylene involves extracting crude oil from the Earth and heating it. This process results in different
types of organic chemicals, some of which are combined to make polypropylene. Polypropylene can then be molded into different
shapes to create a wide range of products.
Which of the following best describes the process that converts crude oil into polypropylene?
A. A synthetic resource undergoes a chemical process to form a natural material.
B. A natural resource undergoes a chemical process to form a synthetic material.
C. Asynthetic resource undergoes a physical process to form a natural material.
D. A natural resource undergoes a physical process to form a synthetic material.
