Final answer:
William Wordsworth believed nature could provide support against loneliness and isolation, as reflected in his poetry that gives human qualities to natural elements and contrasts the comfort of nature with the material struggles of human life.
Step-by-step explanation:
William Wordsworth, known for his love of nature and his poetry that often revolved around it, believed that nature could provide him with support against loneliness and isolation. His experiences throughout life, including the early loss of his parents and his refusal to conform to societal expectations of a regular profession, led him to seek solace in the natural world. In poems such as "I wandered lonely as a Cloud", Wordsworth assigns human characteristics to natural elements (anthropomorphism) and reflects how nature brings comfort and a sense of belonging. This emotional sustenance becomes apparent when compared to the harsh realities he discusses in works like "Last of the Flock" that address themes of poverty and material struggles.
Through his poetry, Wordsworth highlights not only the material struggles faced by individuals but also the deep psychological and emotional support that nature can provide, acting as a balm against the abrasiveness of human life and the encroachment of Industrialization as seen in "The World is Too Much with Us". The answer to the question asked by the student is therefore (a) Loneliness and isolation.
