Asbestos is best described as which of the following?

• A. A synthetic gas
• B. A fiber mineral
• C. A liquid irritant
• D. A radioactive mineral

Answer: (B)

Asbestos is a fiber mineral. It refers to a group of naturally occurring silicate minerals that form long, thin fibers. This fibrous form is what made asbestos valuable for insulation and fireproofing, because the fibers are heat resistant and strong. It is not a gas, so describing it as a synthetic gas is incorrect. It is not a liquid irritant, and it is not inherently radioactive, though some minerals can have trace radioactivity—asbestos itself is defined by its fibrous solid form, not by radioactivity. The key idea is that asbestos is a solid mineral composed of durable, airborne fibers that can cause serious lung diseases if inhaled.
