Roac son of Carc.
Hope it helps!
The first four stanzas discuss the development of the relationship between the River Merchant and his wife. The first discusses when they were in the their childhood. The next discusses her marriage, followed by the maturing of the girl into a woman and the last of the four, talks about the longing or missing of the woman for her husband.
The answer would be 3, a preposition or a conjunction. Hope this helped.
