Because Modernist poets were disturbed with the destruction of the world, they did ALL of the following EXCEPT:
Rejected nineteenth-century literary conventions
Portrayed the hopefulness of mankind after the war
Sought innovative ways to express themselves
Created strange and troubling works
Modernists were disturbed by the world -- therefore, they did not express hopefulness. The did not portray the hopefulness of mankind after the war, especially because the war was so devastating, they did not feel much hope.
