So it was that on the twenty-ninth day of February, at the beginning of the thaw, this singular person fell out of infinity into
Iping village. In this first sentence from the passage, the author uses the words fell out of infinity A) to demonstrate how dangerous the snow was as it began to thaw.
B) to show that the stranger stumbled as he arrived in the village.
C) to show that the stranger just appeared in the village seemingly without a purpose.
D) to explain that the stranger arrived that day without his luggage or any other possessions.
I would choose either c or d, but c seems more logical to me, given the author is stating the visitor's purpose through figurative language, I would assume they would have a more metaphorical purpose to their cause.
