Vermiculite is a mineral used in insulation and other products. One particular vermiculite mine is the source of the majority of vermiculite sold in the United States from 1919 to 1990. The mine also has a deposit of asbestos (another mineral that was also used in insulation), so the vermiculite extracted from that site was contaminated with asbestos. When asbestos-containing materials are damaged or disturbed, microscopic fibers become airborne and, if inhaled, can cause significant health problems. It is strongly recommended that homeowners not disturb any asbestos or asbestos-contaminated material.
Indicate which statement in the table the given information above most strongly suggests is true, and which statement in the table the given information above most strongly suggests is false. Make only two selections, one in each column.

Third statement from top is strongly supported by the following information in the passage:
One particular vermiculite mine is the source of the majority of vermiculite sold in the United States from 1919 to 1990. The mine also has a deposit of asbestos (another mineral that was also used in insulation), so the vermiculite extracted from that site was contaminated with asbestos. When asbestos-containing materials are damaged or disturbed, microscopic fibers become airborne and, if inhaled, can cause significant health problems.
Last statement from top is NOT supported based on the following information in the passage:
It is strongly recommended that homeowners not disturb any asbestos or asbestos-contaminated material.

But it says that absetos were also used in insulation, doesn't that mean that absetos are always present in insulation? and that would make option 1 always true
