Explanation
If Alexander’s generals broke up his empire at his death, then its cohesion must have been weak or short-lived. Both abiding and protracted are nearly the opposite of what you’re looking for, so eliminate choices (A) and (C).
Neither redoubled, which means made twice as great, nor renowned, which means famous, make sense in the blank, so eliminate choices (D) and (E). Both precarious and tenuous can mean weak, so choices (B) and (F) give you appropriate, equivalent sentences.
Hence options B and F are correct!
