The Vocabulary was rich and interesting. Is what I think it is.
The death of a loved one is a disaster that nature cannot heal.
Answer: A
Explanation
Nature will not heal that wound that is left after losing a loved one.
Even though nature creates fascinating patterns, it will not close the wound left.
However, time will be the determinant of the healing process.
This is because the effect of losing someone is eternal, and it is time that will heal the wounds.
Ultimately, nature will only create shorter healing, but once the one forgets about life, the injuries will be still fresh.
Therefore nature does not repair everything.
