The use of allusion in the title and epigraph of nectar in a sieve to emphasize the novel’s political context historical significance themes of loss and hope social and political criticisms

The answer that beat fills the gap is the third option, themes of loss and hope 
Nectar in a Sieve emphasizes the theme of loss and hope since it alludes to the slow drain of the life force of an individual here on earth. Using the nectar as a symbol of life, the sieve slowly drains the nectar until it falls to the ground and becomes useless.
