b. olefin treated with an antimicrobial finish (Olefin has a low resistance to sunlight, heat, and
flame.)
c. silk with a cotton lining (Silk degrades in sunlight.)
d. polyester treated with a flame retardant (Polyester has good resistance to sunlight.)

b. the tile has a coefficient of friction less than 0.60.
c. the tile has a coefficient of friction greater than 0.50.
d. the tile has a coefficient of friction greater than 0.60.
