Step-by-step explanation:
The word that completes the analogy "Sorrow is to joy as ____ is to ease" is "hardship".
Sorrow is the opposite of joy, just as hardship is the opposite of ease. When we experience sorrow, we feel sadness, pain, and difficulty. Similarly, when we experience hardship, we face challenges, obstacles, and difficulties that make things harder and less comfortable. Ease, on the other hand, refers to a state of comfort, relaxation, and freedom from difficulty.
