Answer:
9. sorrow
10. almighty
Step-by-step explanation:
9. Desponence is a term that is quite nuanced and a bit hard to precisely define. It is a noun that denotes emotion or a state of loss of hope, courage or will.
It can be thought of as a state of depression with predominant feelings of sorrow, hopelessness and emptiness.
From the given answers, fury and serenity are not connected to the word whatsoever, while exuberance has completely opposite meaning (an antonym) to the word despondence.
10. In defining the word "omnipotent" we should go back to its origins. It is comprised of Latin prefix omni-, which can be translated as all, whole, total, everything, and the Latin word potent, which means strong, powerful, mighty, of great potency.
Now, knowing this, we can rather easily conclude that the best fitting answer to this would be almighty (capable of everything).
