Final answer:
The blind man in Edward Field's poem may welcome the monster because he cannot judge by appearance and senses other qualities, or because he empathizes with the monster's rejection by society.
Step-by-step explanation:
In the poem by Edward Field, the blind man's reason for welcoming the monster can be analyzed using the RAC method. Considering the evidence from lines 13-17, one can deduce that c) the blind man welcomes the monster due to his inability to judge the monster based on his physical appearance. Being blind, the man is not influenced by the grotesque features that repel others and can therefore sense the creature's other qualities, such as a desire for companionship or a benevolent nature.
Furthermore, embracing the monster might also reflect d) the blind man's empathy with the monster's plight of being rejected by society. The blind man, likely no stranger to marginalization himself, understands the pain of isolation and the monster's yearning for acceptance. Thus, the blind man's kindness may stem from a deep understanding of the monster's social ostracization and his own personal experiences.
