Answer:
**synthetic polymer** [using oil and gas as starting materials]
**alloy** [mixing a metal element with other elements]
**ceramic** [heating clay and sand at high temperatures]
Step-by-step explanation:
Synthetic polymers are derived from petroleum oil such as polyester or nylon.
An Alloy is a mixture of two or more metals with non-metallic elements. Some examples are brass and steel.
A ceramic is an inorganic mixture with metal or non-metal compounds such as sand, which is hardened by heating it to high temperatures.
