I'd like to clarify the choices presented:
-an end to great suffering
-a time of great pain and sorrow
-the helplessness of humans
-the promise of a new beginning
the answer to the question is 'the promise of new beginning'. Viewed in the light of other images that Steinbeck uses, Rose of Sharon's pregnancy likely symbolizes a new beginning.
Answer:
Decorations
Food
Entertainment
Your parents/ friends can help you with the food and maybe the entertainment
and you can do the decorations on your own
Deaths add emotional value to a story. Deaths can be important to a storyline because it effects many things. It effects the other character's emotions, and it's one less character to fulfill things and help with problems.
Also, once a reader has started to feel things from a story, it's harder for them to put the book down. It makes the reader feel a deeper connection to the characters and plot. It adds interest.
