We should be less concerned with students' 'cognitive impatience', however, than by what may underlie it: the potential inability of large numbers of students to read with a level of critical analysis sufficient to comprehend the complexity of thought and argument found in more demanding texts.
I want to know if there is anything omitted before the word sufficient? For instance, that is or which is? If so, is it an adjective clause?
I think this way of writing is quite common but I just realised that I don't understand what it is "technically."
Apart from that, I would appreciate if someone can help me identify the subject, object and all the other elements in this sentence since it's a terrible long one for me, I did spend some time reading it.
