Which plot description is the best example of a tragedy

The best tragedy plot description in my personal opinion is Romeo and Juliet by Shakespeare. Romeo and Juliet is a play about two young star crossed lovers who were divided by their family's ongoing feud, the Capulet's and Montague's.

The lovers desired their family's to cease the spill of civil blood and the involvement of others in their feud. However, Juliet pretended to be dead after a plan established by her and the Friar Laurence to get her back with Romeo who was exiled from Verona for killing Tybalt. Romeo is not delivered the letter intended for him to read informing him about the plan. He therefore hears the news of Juliet's death and drinks posion not baring the sight of Juliet's cold body. Juliet arouses at an instance but is too late and takes her life with a dagger. The prologue is written below. 

PROLOGUE
Two households, both alike in dignity,
In fair Verona, where we lay our scene,
From ancient grudge break to new mutiny,
Where civil blood makes civil hands unclean.
From forth the fatal loins of these two foes
A pair of star-cross'd lovers take their life;
Whose misadventured piteous overthrows
Do with their death bury their parents' strife.
The fearful passage of their death-mark'd love,
And the continuance of their parents' rage,
Which, but their children's end, nought could remove,
Is now the two hours' traffic of our stage;
The which if you with patient ears attend,
What here shall miss, our toil shall strive to mend
