Final answer:
Kya, similar to the marsh grasses, is resilient and has adapted to survive in difficult circumstances after being acquitted, reflecting the marsh's ability to endure and thrive in a changing environment.
Step-by-step explanation:
When Kya is alone in her home after being acquitted, there is a comparison drawn between her solitude and the marsh grasses she begins to paint. The marsh grasses, surviving in a challenging and changing environment, are resilient and adaptable. Much like the grasses, Kya has endured isolation and evolved to thrive in her surroundings, despite societal pressures and the harsh realities of the environment in which she lives. Her connection to the marsh and her adaptation to life's circumstances parallel the enduring and resilient nature of the marsh grasses amid the constant ebbs and flows of the tide.
