问题 Apart from its low cost, the appeal of iron as a building material lay in its strength, its______to fire, and its potential to span vast areas.

选项 A、assignment
B、resistance
C、adjustment
D、liability

答案B

解析 四个选项的意思分别是assignment“分配,委派”;resistance“抗耐性,承受某一有害的环境的能力”,如The aircraft is streamlined to cut down wind resistance(飞机设计成流线型以减少风的阻力);adjustment“调整,调节”;liability“责任,义务”。句子的意思是,钢铁作为建筑材料之所以很有吸引力,除了价格低以外,还有防火、能覆盖很大区域的特点。所以正确答案是B选项。
