Read the excerpt below from an essay by author and social critic, Rebecca Solnit. In this passage, Solnit discusses the concept of 'walking' and how it relates to freedom and exploration in both physical and metaphorical spaces. Analyze the rhetorical strategies she employs to convey her message about the importance of mobility as a means of liberation.

"Walking has been inextricably linked to freedom. As long as we can walk, we can define our own paths; as long as we can wander, we can resist confinement. Each step forward is not just a movement through space but an assertion of our autonomy against societal constraints. With urban landscapes constantly evolving, the act of walking becomes a political act, challenging the structures that seek to limit us. When we tread upon a pavement, we reclaim not just our physical presence but our agency in navigating the world around us."

In a well-organized essay, analyze the rhetorical strategies used by Solnit. Consider how these strategies contribute to her overall argument about mobility and freedom. Support your analysis with specific examples from the text.
