In the lyrics, what does the "rainbow highway" symbolize?

The symbolism of the "rainbow highway" in the lyrics represents a path to hope and dreams. Rainbows often embody positivity, beauty, and the promise of better times following a storm. In this context, the highway suggests a journey where individuals can pursue their aspirations and find solace. This imagery evokes a sense of optimism and the belief that there is a way to transcend challenges and reach one's goals. Therefore, interpreting the "rainbow highway" as a symbol of hope aligns with common associations of rainbows in literature and culture, which celebrate possibilities and new beginnings.

The other options reflect different interpretations but do not capture the essence of hope as effectively as this choice does. For example, while the journey through life may involve ups and downs, the specific imagery of a "rainbow highway" leans more toward an optimistic pathway rather than just the overall journey itself.
