Answer:
PART A: B). No one can live a full or happy life if they are denied freedom.
PART B: A). “I know what the caged bird feels, alas! / When the sun is bright on the upland slopes;” ( Lines 1-2)
Explanation:
The central idea that Paul wishes to convey through this poem is that 'no individual can live a contented and joyous life when they are denied their due liberty.' The poet sympathizes with the caged birds as he could feel their pain of inability to live their life independently and express their emotions or feelings. Thus, option B is the correct answer.
The quotation 'I Know...slopes' supports the above idea as it reflects that how the caged birds feel when they could see the bright sun rising above the slopes which reinforces the idea of significance of freedom in one's life and the reluctance to live when they are neglected liberty as it not only snatches their ability to live but also their freedom of expression. Thus, option A is the correct answer.
