Answer:
The word "strife" means conflict.
Odysseus's glimmer of pride when he loses his temper at the Phaeacian athletic games can be considered as foreshadowing his encounter with Polyphemus.
Explanation:
1. Odysseus and Achilles were on opposing sides of each other at the battle of Troy. So, according to the passage provided in the question, strife will denote the conflict of these two characters.
2. In Book VIII of "The Odyssey", Odysseus was invited to participate in the games that were organised by the King. When he refused, the youths taunt him, goading him to participate. When he did, he boasted about his experience and strength, in comparison to those young youths who were part of the game. This is a foreshadowing of his encounter with Polyphemus, the Cyclops son of Poseidon in Book IX.
