What drives Twilly to take drastic actions like setting the billboard on fire?

The choice indicating that Twilly's actions are driven by a passion for environmental activism provides a deep insight into his motivations. It suggests that he is profoundly concerned about environmental issues or injustices linked to the airline industry. By setting the billboard on fire, Twilly likely aims to draw attention to environmental concerns or to protest against practices he believes contribute to ecological harm.

This context implies that his drastic actions stem from a larger ideological commitment, demonstrating how passionate individuals may resort to extreme measures when they feel their cause is urgent and not adequately addressed through conventional means. Twilly's actions could therefore be interpreted as a desperate but intentional statement intended to provoke thought or inspire change regarding the environmental impact of the airline.

In contrast, the other options suggest motivations that do not align as strongly with the drastic nature of setting a billboard on fire. A need for attention might prompt less destructive behavior, a personal connection to the airline implies a more sentimental motivation that likely wouldn’t incite protest, and frustration with his social life would pertain to personal struggles rather than a larger cause related to activism.
