Final answer:
The imagery of 'a hopeless battle' represents the struggle of individuals against a repressive collective society (d), illustrating the theme that group thinking suppresses mankind's potential.
Step-by-step explanation:
- The imagery of “a hopeless battle” in the excerpt from Anthem helps to develop the theme that group thinking limits man’s potential because it depicts the collective society as a destructive force that represses the independent thinker.
- This metaphor suggests that even when individuals are aware that they are against overwhelming odds, they still choose to fight for their beliefs, knowing full well that they may not survive.
- The choice to fight a losing battle underscores the value these individuals place on independent thought, in stark contrast to a society that enforces conformity and suppresses individuality.
