Final answer:
The third action taken by the speaker in Nissim Ezekiel's "Background, Casually" is not specified in the reference material provided. The original poem should be consulted to identify the correct answer.
Step-by-step explanation:
In "Background, Casually" by Nissim Ezekiel, the third thing the speaker does to prepare for the worst back in India, in addition to changing jobs and seeing himself as a fool, is not directly mentioned in the provided reference material. However, the four options provided suggest specific actions, and the reference material does not seem to match any of these. Therefore, it's essential to refer to the original text of "Background, Casually" to accurately determine the third thing the speaker does. If the text is not available for review, it might be best to refrain from guessing and advise the student to consult the poem directly to ensure an accurate answer.
