Final answer:
Eben Flood's portrayal as a lonely, alienated man and the emphasis on his life's disappointments in 'Mr. Flood's Party' are reflective of modernist characteristics in literature.
Step-by-step explanation:
Details from "Mr. Flood's Party" by Edwin Arlington Robinson that reflect characteristics of modernism include the portrayal of Eben Flood as a lonely man alienated from his surroundings and the focus on the disappointments in his life through lines like "A valiant armor of scarred hopes outworn." These aspects of the poem reflect the modernist themes of isolation, disillusionment, and the breakdown of traditional values. In contrast, Robinson's treatment of Flood as a hero and the character's focus on overcoming obstacles are not typically modernist traits, which often underscore the failure to find meaning or triumph over adversity.
