The most fitting summary of how the passages support themes about nature and human perception is:
Nature and humanity can be reflections of one another.
Both passages illustrate the interplay between the natural world and human experience. In "Kew Gardens," nature is vibrant and teeming with life, interacting with human figures who move through it, suggesting a complex relationship where human emotions and perceptions are intertwined with the environment. Similarly, in "A Cup of Tea," the bleak winter landscape and Rosemary's feelings emphasize her emotional state in relation to the nature surrounding her. Each setting reflects the characters' experiences, highlighting how human perception is deeply connected to the natural world.
