The right answer is conversational. Below is a brief explanation of the author and his writing style.
Henry David Thoreau was an American author, poet, naturalist, anti-tax activist, critic of the idea of development, researcher, historian, philosopher, and transcendentalist. He is best known for his book Walden, a reflection on the simple life surrounded by nature, and for his essay Civil Disobedience a defense of individual civil disobedience as a form of legitimate opposition to an unjust state. His style of literary writing interweaves natural observations, personal experience, punctuated rhetoric, symbolist meanings, and historical data; while at the same time showing great poetic sensibility, philosophical austerity, and a "yankee" passion for practical detail.
