The correct option for the tone of the poet in the excerpt from Ibiwari Ikiriko's "Oily Tears" is A. optimistic. Step-by-Step Explanation:

1. Understanding Tone: The tone of a poem refers to the attitude or emotional quality that the poet conveys through their choice of words and imagery. It can reflect feelings such as joy, sadness, anger, hope, or despair.
2. Analyzing the Excerpt:
3. The lines "These oily tears / Dripping down the tears on your depressed face" suggest a deep sense of sorrow and pain. The imagery of "oily tears" evokes a strong emotional response, indicating that the subject is experiencing significant distress.
4. However, the phrase "Will one day be staunched, / I swear!" introduces a shift in tone. The use of "will" indicates a future possibility, suggesting hope and a belief that the current suffering will eventually come to an end. The word "swear" adds a personal commitment to this belief, reinforcing the sense of optimism.
5. Why Option A is Correct:
6. The poet expresses a belief that the tears (representing sorrow) will eventually stop, which is a hopeful outlook. This forward-looking perspective is characteristic of an optimistic tone. The poet is not merely lamenting the pain but is also affirming that healing and relief are possible.

Evaluating Other Options:

• B. Supplicatory: This tone would imply that the poet is pleading or begging for something. While there is an element of yearning for relief in the poem, the primary focus is on the assurance of future healing rather than a plea for help. Therefore, this option does not capture the essence of the poet's message.
• C. Sympathetic: A sympathetic tone would indicate that the poet is expressing compassion or understanding towards someone else's suffering. While the poet does show awareness of the pain, the emphasis is on hope for the future rather than merely sympathizing with the current state of distress. Thus, this option is weaker than the optimistic interpretation.
• D. Piteous: A piteous tone conveys a sense of deep sorrow or pity, often evoking feelings of compassion from the reader. While the poem does express sorrow, the concluding lines shift the focus towards hope and healing, making this option less fitting than the optimistic tone.

Summary of Key Points:

• The tone of the poem is optimistic because it expresses hope for future healing.
• The imagery of tears indicates sorrow, but the promise of relief shifts the tone positively.
• Other options like supplicatory, sympathetic, and piteous do not capture the hopeful outlook conveyed by the poet.
• Understanding tone involves analyzing word choice and emotional shifts within the text.
