Task: Question Generation
Input (English): Passage: The archangel Gabriel appears before Mary to announce that she will bear the Son of God.  He is shown standing in a three-quarter view wearing a small jeweled diadem and dressed in vestments. He has a richly embroidered red-and-gold brocade cope, edged with a pattern of gray seraphim and wheels, over a white alb and amice. He holds his staff of office in one hand, and raises the other towards the Virgin. He bends his knees, honoring and acknowledging her as Mother of Christ and Queen of Heaven, and his feet are bare and positioned slightly behind hers.The Virgin is in a frontal view; directly behind her the red-curtained bed acts as a framing device, similar to the traditional canopy-of-honor or baldachin. Unlike Memling's predecessors whose Virgins are garbed in heavily jeweled and costly robes, the plain white shift she wears beneath a blue mantle is minimally jeweled at the hem and at the open neckline. A purple underdress peeks out at her neck and wrists, indicating her royal status. Mary seems neither surprised nor fearful at the announcement; according to Blum the scene is rendered with a great sense of naturalism and successfully depicts "the transformation of Mary from girl to God-bearer.".
Output (English): What two titles are given to the person wearing a blue mantle that is minimally jeweled at the hem?
