Word order in "either/or" parallel structure

Solution 1:

While both sentences are correct, the second is preferable because it eliminates repeating the word from. It would be a different story if you needed different prepositions, but you don't.

Look at it very logically and almost mathematically with two correct examples:

"Either from A or into B." I used into to show another preposition besides from. Since the either serves as a fork before mention of A or B, you need insert a preposition for each.

"From either A or B." That idea means from A and from B. Since the either serves as a fork after you mentioned from, the word from applies to both A and B. (Notice I did not say to A and to B.) Do not insert a preposition for each unless the sentence is so long that most readers will forget their place.

So if you need two prepositions, that works well to set up the parallel construction. If you do not, have the single preposition apply to both A and B by placing it before the either.

Similar parallels: I love both my father and mother. I both love and admire Pat.
