Question

in anthem, the narrators name, equality 7-2521, helps to develop a theme that
all people deserve equal opportunity.
individuality is lost in a collective society.
brotherhood and cooperation strengthen society.
individual differences are inconsequential.

Explanation:

In Anthem, the society enforces collective identity by stripping people of unique personal names, assigning them generic labels like Equality 7-2521 instead. This naming system erases individual identity to prioritize the group, directly illustrating how individuality is suppressed in a collective-focused society. The other options do not align: the name does not emphasize equal opportunity, it undermines (rather than supports) the idea of brotherhood as a positive, and it highlights that individual differences are intentionally erased, not that they are inconsequential.

Answer:

individuality is lost in a collective society.
