Which group of words best conveys the overall theme of the passage?

The question asks for the group of words that best conveys the overall theme of the passage. In this context, option C, which includes "although, accidentally, lowly, doubtful," does not align well with a positive theme associated with accomplishment, ambition, or recognition. In fact, these words suggest a more negative or uncertain perspective.

On the other hand, the other options present stronger themes of achievement and success. For instance, the groups that include words like "achievement," "success," "goal," and "ambition" represent aspirations and positive outcomes, whereas "fame" and "glory" imply recognition resulting from effort and hard work.

The correct answer would likely focus on a theme that reflects upward mobility, personal growth, and the fulfillment that comes from reaching one's goals, rather than the negative connotations suggested by the words in option C. This context points towards the idea that the overall theme encapsulates the journey towards success and the rewards that come with it, which are more accurately represented in the other options.
