Final answer:
In "Telephone Conversation," the speaker's attitude shifts from being upset to playfully taunting the landlady.
Step-by-step explanation:
In the poem "Telephone Conversation" by Wole Soyinka, the most accurate description of the shift in the speaker's attitude toward the landlady is from fuming to mischievous. Initially, the speaker is indignantly taken aback by the landlady's blunt racist remarks when asking about his skin color. As the conversation progresses, the speaker's attitude shifts to a mischievous tone as he starts to play with the landlady's ignorance and racism, turning the tables on her by providing literal and sardonic responses to her questions about his skin color.
