Answer:
The correct answer is: true.
Explanation:
A big part of Byron's contemporaries in England rejected him and his overstretched imagination. Byron's contemporaries rejected him because his poetry was exuberant and expansive, with a lot of lucid but spontaneous elements, colloquial, an overstretched portrait of adorned reality.
However, all these characteristics determined Byron's poetry, as its most outstanding elements, and helped him create one of the most important poems in English literature - Childe Harold's Pilgrimage.
