Final answer:
The figurative language used is metaphor, which emphasizes the alluring nature of indifference and underscores its dangerous appeal.
Step-by-step explanation:
The figurative language used in the fifth paragraph is metaphor. Wiesel describes indifference as tempting and seductive, emphasizing its alluring nature. By comparing indifference to something that is tempting and seductive, the metaphor highlights the dangerous appeal of indifference. It suggests that indifference can easily entice people and lead them to disregard the suffering of others. This supports Wiesel's main ideas about indifference by showing how it can lead to apathy and inaction, allowing injustice and suffering to persist.
