This sentence is very long, and it is necessary to pay attention to the author's logic when considering ways in which the sentence might be rephrased. Notice that the author says that there are two standards of value that will make the status of the Bible seem questionable if they are rigorously applied. (This is the author's opinion. We are not here to get into the justifications for his reasoning.) They are:
(1) To say that the book was composed automatically or at least that it was not composed by the free caprice of the writer
(2) To say that it must have no scientific and historic errors and express no local or personal passions
Now, the confusing part is the fact that (1) and (2) are joined by an "or," but (1) also has an "or" in it as well. There really is a case of correlative conjunctions here: either 1 or 2. However, to make this clear, the correct answer isolates the "secondary" "or" that is found in (1).
