Answer:
the certainty of old age and death
Explanation:
Good luck on your final exam. I would say its to do with aging and death as autumn refers to dead leaves and the leading up to winter, death of vegeation. Dying fire, burns but it the fire will soon come to an end and a sunset, it is beautiful but it only lasts for a while before transcending into complete darkness, as in night.
Hope this makes sense??
