What new sense of hope does Denny gain after his parents' visit?

Denny's sense of hope after his parents' visit mainly revolves around his future with Zoë. Throughout the narrative, Denny often grapples with feelings of isolation and uncertainty, especially concerning his role as a father following the challenges he faces. The visit from his parents acts as a catalyst for reconnecting with family ties and reinforces the notion of stability and support for his daughter, Zoë. This restores his confidence in his ability to navigate the obstacles they face together.

The other options may represent significant aspects of Denny's life, but they do not encapsulate the fundamental shift in hope stemming from his parents' visit. His relationship with Annika, while pivotal, is not the primary concern reflected in that moment. Similarly, his career as a racecar driver holds its own significance, but it is ultimately his role as a father and the future he envisions with Zoë that brings him a renewed sense of optimism. Winning a race, though a noteworthy ambition, does not capture the emotional depth associated with family connections and the love he has for his daughter.
