An important theme, or message, in romeo and juliet is the struggle against fate, or forces that determine how a person's life will turn out. explain how act i's prologue establishes the fate of the main characters and introduces the struggles they will face.

Romeo and Juliet begins with a Chorus, which establishes the plot and tone of the play. This device was hardly new to Shakespeare, and in fact mirrors the structure of Arthur Brooke's The Tragical History of Romeus and Juliet, from which Shakespeare adapted Romeo and Juliet.

Additionally, the Chorus poses the question of whether or not Romeo and Juliet is a tragedy. During Shakespeare's time, it was typical for a tragedy to begin with a Chorus. In Romeo and Juliet, the opening sonnet presents dire enough circumstances to support that convention. However, tragedy in its strictest form presupposes certain formal conceits. Most important is the idea that an individual (or individuals) is (or are) defeated by forces beyond his or her control; tragedies most often celebrate human willpower in the face of bad luck or divine antagonism. And yet, the forces at play in Romeo and Juliet are hardly beyond human control. Instead, the Montagues and Capulets have allowed their feud to fester. This is evident from the first scene, when even the patriarchs of both families enter the public street fight, ready to kill. The Chorus introduces Shakespeare's unique approach to tragedy by introducing certain established tropes of that genre but by refusing to lay the blame at the universe’s feet.

In addition, the Chorus also introduces certain sources of dramatic tension that re-appear throughout the rest of the play. For example, the diametric opposition between order and disorder is central to to Romeo and Juliet. In the Prologue, the Chorus speaks in sonnet form, which was usually reserved for a lover addressing his beloved. The sonnet is a very structured form of poetry, which indicates a level of order

In the beginning, Act I tells us how Romeo and Juliet was forbidden to fall in love because of their families.

(you didn't attach a copy of the poem, but i'm answering as best as i can)

since a simile compares two unlike things using like or as, it kind of gives an item the ability to do something it can't.

example: "the player was like a tiger on the field"

in this sentence, the simile conveys the idea that the player was fast and strong, like a tiger.
