Question ID:PT60 S1 Q8 Passage:Adobe is an ideal material for building in desert environments. It conducts heat very slowly. As a result, a house built of adobe retains the warmth of the desert sun during the cool evenings and then remains cool during the heat of the day, thereby helping to maintain a pleasant temperature. In contrast, houses built of other commonly used building materials, which conduct heat more rapidly, grow hot during the day and cold at night. Stem:Which one of the following most accurately expresses the main conclusion drawn in the argument above? Correct Answer Choice:EChoice A:Adobe is a suitable substitute for other building materials where the heat-conduction properties of the structure are especially important. Choice B:In the desert, adobe buildings remain cool during the heat of the day but retain the warmth of the sun during the cool evenings. Choice C:Because adobe conducts heat very slowly, adobe houses maintain a pleasant, constant temperature. Choice D:Ideally, a material used for building houses in desert environments should enable those houses to maintain a pleasant, constant temperature. Choice E:Adobe is an especially suitable material to use for building houses in desert environments.
