Final answer:
William Wordsworth is the author known for wandering the English countryside for inspiration and peace, significantly contributing to Romantic poetry with works like 'I Wandered Lonely as a Cloud.' Option 4 is correct.
Step-by-step explanation:
The author who wandered the English countryside to find inspiration and peace was William Wordsworth, a quintessential Romantic poet. Wordsworth is well-known for drawing inspiration from the natural landscape, which served as a potent source of poetic material and a backdrop for his contemplation and reflection. As a key figure in the Romantic Movement, his works encapsulate the era's inclination towards emotion, nature, and the individual's experience.
Wordsworth's extensive walks in England and Wales, his transformative time in France, and his deep connections with his fellow Romantic poets and artists, like Samuel Taylor Coleridge and the painter William Green, significantly influenced his poetry. His most famous works, including I Wandered Lonely as a Cloud and The World Is Too Much with Us, are enduring testaments to his love of nature and his philosophies as a Romantic poet.
