　　请解释下这个英语阅读理解题为什么选这个答案

　　原文

　　前几段与题目无关,我省略了,直接把相关段落复制如下：

　　Somepeoplearedisabledinaccidents.Manyothersmayhaveaperiodofdisabilityintheformofamentalillness.Allareaffectedbypeople'sattitudetowardsthem.

　　a.weshouldtryourbesttopreventdisablement

　　b.bothphysicalandmetalbarriersarehardtobreakdown

　　c.wejusttakeaproperattitudetowardsthedisabled

　　d.theable-bodiespeoplewillneverfullyunderstandthedisabled

　　正确答案是C

　　请问,C的中文怎么理解,尤其是那个just

　　我怎么觉得B更加正确呀,不是在最后一段里有Butthereareotherbarriers:prejudicecanbeevenhardertobreakdown...

　　prejudice不就代表了精神方面的阻碍,既然用了evenharder,那说明前面讲的physicalberrier也是hardtobreakdown,那不是该选B么?
