Final answer:
The best word to describe the speaker's tone in the poem “At the Tourist Centre in Boston” is 'mocking', as it suggests a critical and scornful attitude towards the artificial tourist experience being presented.
Step-by-step explanation:
The tone of the speaker in the lines from the poem “At the Tourist Centre in Boston” suggests an element of skepticism and questioning the reality of the scenes presented to them. The speaker's use of the words “manufactured hallucination,” “cynical fiction,” and “lure” imply a tone that is critical and possibly mocking the artificiality of the tourist experience. This tone aligns with the definition of mocking, which is to make fun of someone or something in a scornful way. Therefore, option D, mocking, best describes the speaker’s tone. While the words “curious” and “inquiring” could be considered, they lack the critical, satirical edge that is implied by the speaker's word choice. “Irate” suggests anger which may not be directly indicated by the selected lines. The tone of voice in a poem contributes significantly to the underlying meaning and the reader's perception of the speaker's attitude towards the subject matter.
