Over here the poet is making his heart similar to an apple tree that is bent with lots of fruit. My heart is so heavy like a tree whose branches are bent by thick fruits. So here the poet is sad.

Things that happen in a story can help you find out the theme, like if a character does something and lies about it, and then other characters find out and that first character gets consequences, then the theme of the story is to not lie.
The correct answer is B. an allusion
Foreshadowing is when you use symbols to tell what's going to happen in the future, a hyperbole is over-exaggerating, while symbolism is using symbols to represent other concepts. Allusion is used for referring to famous works.
C, progressive verbs have an -ing at the end (entering), because they represent an action that is currently being done or will be occurring at some point in time.
