Grave diggersi?? between Marx and Engels

In The Communist Manifesto, Marx and Engels, in one passage, write about the conflict between the bourgeoisie and the proletariat (pgs. 478-9):

i??But not only has the bourgeoisie forged the weapons that bring death to itself; it has also called into existence the men who are to wield those weaponsi??the modern working classi??the proletarians. In proportion as the bourgeoisie, i.e., capital, is developed, in the same proportion is the proletariat, the modern working class, developedi??a class of laborers, who live only so long as they find work, and who find work only so long as their labour increases capital. These labourers, who must sell themselves piece-meal, are a commodity, like every other article of commerce, and are consequently exposed to all the vicissitudes of competition, to all the fluctuations of the market.i??

And in another passage (p. 483), Marx and Engels concludes with the following sentence:

i??What the bourgeoisie, therefore, produces, above all, is its own grave-diggers. Its fall and the victory of the proletariat are equally inevitable.i??

In this brief essay, explain the meaning of the first passagei??as you understand iti??and how it relates to the second. To do so, you will need to read the whole assignment of The Communist Manifesto. In interpreting this passage, you will want to include an explanation of who the bourgeoisie and the proletariat are, what Marx and Engels mean when they write the bourgeoisie i??forged the weapons to bring death to itself,i?? what the relation is between those i??weaponsi?? and the proletariat, and why Marx and Engels conclude by arguing the bourgeoisie produce their own i??grave diggers.i??
