Editor: Most of the books of fiction we have published were submitted by literary agents for writers they represented; the rest were received directly from fiction writers from whom we requested submissions. No nonfiction manuscript has been given serious attention, let alone been published, unless it was from a renowned figure or we had requested the manuscript after careful review of the writer' s book proposal. Which one of the following can be properly inferred from the editor's statements? ['Most of the books that the publishing house publishes that are not by renowned authors are books of fiction.', "The publishing house is less likely to give careful consideration to a manuscript that was submitted directly by a writer than one that was submitted by a writer's literary agent.", 'Any unrequested manuscripts not submitted by literary agents that the publishing house has published were written by renowned figures.', 'Most unrequested manuscripts that the publishing house receives are not given serious attention.']
