Q1: Most of the books of fiction we have published were submitted by literary agents for writers they represented
Q1: FP-most-SLA SLA-some-FP
Q2: the rest (since the others were majority, the rest will be less than a majority, i.e. some) were received directly from fiction writers from whom we requested submissions.
Q2: FP-some-RS RS-some-FP
Now, of the fiction books published, we have a special case where they were either submitted by literary agents, or they were requested submissions. There is no other way a book of fiction was published by this editor. Therefore, taking in the first two statements in context, this mean that if it was a book of fiction published by the editor, then it was submitted by a literary agent or they requested the submissions:
FP ==> SLA or RS not SLA and not RS ==> not FP
P1: 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.
So: if a nonfiction manuscript was given serious attention or it was published, then it was from a renowned figure or we had requested the manuscript.
P1: NFSA or NFP ==> RF or RS not RS and not RF ==> not NFSA and not NFP
We are asked which answer choice must be true.
Well, (E) tells us that we have "not SLA and not RS" meaning - according to the principle rule we came up with in context - that the published book was not a work of fiction. So, if a nonfiction work was published, we know - according to P1 - that it was either from a renowned figure or the editor had requested it. Well, we know that it was unrequested. So, it must be true that it was from by a renowned figure. Therefore, answer choice (E) is correct.
Hope that helps! Please let us know if you have any other questions.
