Task: Question Generation
Input (English): The popularity of this particular representation of The Immaculate Conception spread across the rest of Europe, and has since remained the best known artistic depiction of the concept: in a heavenly realm, moments after her creation, the spirit of Mary (in the form of a young woman) looks up in awe at (or bows her head to) God. The moon is under her feet and a halo of twelve stars surround her head, possibly a reference to "a woman clothed with the sun" from Revelation 12:1-2. Additional imagery may include clouds, a golden light, and cherubs. In some paintings the cherubim are holding lilies and roses, flowers often associated with Mary.
Output (English): What does Mary stand upon in this symbol?
