The correct answer is - draw inspiration from the natural world.
For Romantic writers and poets, nature is everything - it is where they find the inspiration for writing their texts and poems. Nature in their works often reflects either their, or their characters' feelings and opinions. Romantic writers would often escape into nature, in order to remove the society and urban life from their thoughts, and give themselves in to nature because it was their muse. Wordsworth was one of the poets who managed to do this best.
