What attitude does the speaker display towards the youth who have passed?

The choice that highlights the speaker's attitude as one that celebrates the brief lives of the youth who have passed is particularly compelling because it reflects a recognition of the vibrancy and potential of those young individuals. This attitude signifies an appreciation for the unique experiences and joys that each of these lives encompassed, even if they were short-lived.

Celebration in this context can be interpreted as a way of honoring their existence, acknowledging the impact they made during their time, and valuing their contributions to life, however fleeting. The speaker seems to embrace the notion that even a brief life can be meaningful and worthy of remembrance. This perspective invites a deeper understanding of life itself, emphasizing the importance of living fully, regardless of the duration of one's existence.

In contrast, the other options suggest different emotional responses: frustration implies a sense of loss without recognition of the positives; indifference would indicate a lack of emotional connection or acknowledgment of the youths' lives; and sympathy for the living shifts the focus away from the celebrated lives of those who have passed. All these contrasting emotions affirm that the speaker's attitude is indeed one of celebration rather than despair or apathy.
