The correct answer is sentence (5).
A sentence fragment means that it is only a part of a sentence; it is not complete. Given that it is incomplete, the fragment, aka subordinate/dependent sentence, has to be part of a larger, independent sentence, in order to make any sense. So if you combined sentence (5) with another one, it wouldn't be a fragment anymore.
The resolution should be the last ending part, so it should be Maura and her mother pulled themselves out onto the river bank
Which book is this? :P lol
I would say she shuts herself away after hearing of her husband's death because she wouldn't be willing to except help or anything else.
