Ceramic floors require large amounts of water to be kept clean. Carpets, however, do not need water to be cleaned. An environmental protection group is urging the public to use carpeted flooring instead of ceramic tiles since carpets save water and, therefore, are better for the preservation of resources.
Which of the following, if true, undermines the environmental protection group's explanation for the preferred use of carpeted flooring?
A. Ceramic flooring is usually more expensive than carpeting although this depends greatly on the actual products that are used.
B. Carpets do not provide the same degree of heat insulation that is provided by ceramic tiles.
C. The firing process in the manufacturing of ceramic tiles requires the burning of large amounts of wood.
D. Water and other resources can only be successfully preserved on the basis of a close cooperation between environmental ideologists and citizens.
E. Carpets need to be vacuumed and, therefore, require electricity; in most countries this implies increasing the fossil fuel consumption of a household.
