Style manual: Archaic spellings and styles of punctuation in direct quotations from older works are to be preserved if they occur infrequently and do not interfere with a reader' s comprehension. However, if they occur frequently, the editor may modernize them, inserting a note with an explanation to this effect in the text, or if similar modernizing has been done in more than one quotation, inserting a general statement in the preface. On the other hand, obvious typographical errors in quotations from modern works may be corrected without explanation. Which one of the following follows logically from the statements above? ['An editor may modernize punctuation directly quoted from an older work if that punctuation occurs frequently and interferes with reader comprehension.', 'If an editor corrects the spelling of a quoted word and the word occurs only once in the text, then an explanation should appear in a note or in the text.', 'If an editor modernizes only one of several similar instances of quoted archaic punctuation, an explanation should appear in the preface of the work.', 'An editor may modernize an archaic spelling of a word found in a modern work without providing an explanation.']
