You know what must be organized, but the sentence conceals who is responsible for organizing that material. But it is always important to check to make sure that your sentence points to the do-ers and the doing you want it to. It is the responsibility of those who write in a scholarly manner to order their material in a clear way so that their material will have been, by them, appropriately organized. This sentence is grammatically correct, and it is highly complex. But the author of such a sentence may be misled into thinking that the sentence says much more than it really does.
Nothing happens there, at least nothing that is important to the sentence.
But the problem is not just that the sentence is unnecessarily wordy. Circle the main subject and the main verb. The point is not always to produce the shortest phrase, or the shortest sentence. The whole purpose of this editing method is to help you be sure that you know exactly what you mean. Then, by adjusting your subjects and verbs accordingly, you can make sure you are also expressing your real ideas in the clearest and most appropriate ways.
