问题 What part of the museum flooded? [br]  
Dozens of valuable paintings and frescoes were badly damaged when rainwater poured through a roof at the state museum. As freak rainstorms lashed in the central and southern sections of the state, part of the museum’s roof which was scheduled to be repaired collapsed and water cascaded into two storerooms.
A heater is using convection when it warms the air in a room. And the air in turn warms the people and objects in the room. A hot water radiator, a stove and forced air furnace are all convection heaters. A quartz heater, on the other hand, heats the objects and people in a room without heating the air. It does this by producing radiation heat that travels like light waves. The radiation is then directed at objects by means of a reflector.

选项 A、It heats only the objects in a room.
B、It is lighter in weight.
C、It heats the room quicker.
D、It is more common.

答案 A

解析 原文介绍了几种散热器,其中重点介绍了quartz heater(石英散热器)。在描述该物时,说话者介绍“A quartz heater, on the other hand, heats the objects and people in a room without heating the air.”即“而石英散热器在温暖房中的人和物时,却不会加热房中的空气”,选项a的说法与原文相符,因此是正确答案。
