Questions Refer to the Passage Below

Questions refer to the passage below.
The basis of irreligious criticism is this: man makes religion; religion does not make man. Religion is indeed man's self-consciousness and self-awareness so long as he has not found himself or has lost himself again. But man is not an abstract being, squatting outside the world. Man is the human world, the state, society. This state, this society, produce religion which is an inverted world consciousness, because they are an inverted world. Religion is the general theory of this world, its encyclopedic compendium, its logic in popular form. . . . The struggle against religion is, therefore, indirectly, a struggle against that world whose spiritual aroma is religion.
Religious suffering is at the same time an expression of real suffering and a protest against real suffering. Religion is the sigh of the oppressed creature, the sentiment of a heartless world, and the soul of soulless conditions. It is the opium of the people.
The abolition of religion as the illusory happiness of men, is a demand for their real happiness.
Karl Marx, critique of religion, 1843
