Final answer:
Unoka is a foil character to Okonkwo in Chinua Achebe's novel 'Things Fall Apart' because he contrasts with Okonkwo in terms of wealth, strength, ambition, and temperament.
Step-by-step explanation:
In Chinua Achebe's novel 'Things Fall Apart', Unoka serves as a foil character to Okonkwo. A foil character is a character who contrasts with another character, highlighting their differences and enhancing the reader's understanding of both characters.
Unoka is poor and weak, while Okonkwo is wealthy and strong. Unoka's lack of ambition and his preference for music and idleness sharply contrast with Okonkwo's hardworking and ambitious nature.
Additionally, Unoka's easygoing personality and peaceful approach to life clash with Okonkwo's hot-tempered and violent demeanor. Through their differences, Achebe helps to illustrate the complexity of Okonkwo's character and explore the themes of success, masculinity, and tradition in the novel.
