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：
Some people are disabled in accidents. Many others may have a period of disability in the form of a mental illness.All are affected by people's attitude towards them.
Disabled people face many physical barriers.Next time you go shopping or to work or visit friends,imagine how you would manage if you could not get up steps,or on to buses and trains.How would you cope if you could not see where you were going or could not hear the traffic? But there are other barriers:prejudice can be even harder to break down and ignorance inevitably represents by far the greatest barrier of all. It is almost impossible for the able-bodied to fuly appreciate what the severely disabled go through,so it is important to draw attention to these barriers and show that it is the individual person and their ability,not their disability,which counts.
5.It can be concluded from the passage that____.
a.we should try our best to prevent disablement
b.both physical and metal barriers are hard to break down
c.we just take a proper attitude towards the disabled
d.the able-bodies people will never fully understand the disabled
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But there are other barriers:prejudice can be even harder to break down ...
prejudice不就代表了精神方面的阻碍,既然用了even harder,那说明前面讲的physical berrier也是hard to break down,那不是该选B么?

优质解答

但是从全文看,从主旨上来看,因为题目里说conclude from the the passage,所以从全文上来看看.
it is the individual person and their ability,not their disability,which counts.就是we shuold take a proper attitude.
just,作副词,我没查到什么合适的意思.
B项是对的,可是我觉得它不是全文想最终传达的.
