The best answer is: The speaker in the former knows exactly what her goal is, while the speaker in the latter believes that she has already achieved it.

Explanation:

• In Emily Dickinson’s “Because I could not stop for Death,” the speaker clearly understands her goal or destination: death and the afterlife. She is aware of the journey she is on, even though it is inevitable and beyond her control.
• In contrast, in “Some Keep the Sabbath Going to Church,” the speaker expresses a sense of having already achieved her spiritual goal by keeping the Sabbath in her own way-at home, with nature-rather than going to church. She feels fulfilled and at peace, implying her spiritual goal is already realized.

The other options don’t fit as well:

• The speaker in the former does not express doubt about reaching her goal; death is certain.
• The speaker in the former is indeed interested in the goal (death/afterlife).
• The speaker in the former views the goal as real and definite, not intangible.
• The speaker in the latter does not consider her goal too distant; she feels she has it now.

Thus, the key difference is the former speaker’s clear awareness of the goal ahead, while the latter speaker feels she has already attained her spiritual aim.
