Final answer:
The question about Hrani's advice to King Hrolf cannot be answered as it is not referenced in the provided texts; the excerpts relate to different topics and characters.
Step-by-step explanation:
The question posed is about advice Hrani gives to King Hrolf, which is not directly referenced in the provided texts. Therefore, I am unable to provide an answer to this question. Among the various texts included, advice and decision-making are common themes, such as Leif Ericson considering an exploration proposal from Biarni Heriulfsson, or the dialogues in Henrik Ibsen's 'A Doll's House' where characters negotiate moral dilemmas and their social standings. However, none of these excerpts supply information regarding Hrani's advice to King Hrolf.
