Instructions: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Input: Passage: The neck guard, flared outward to protect the shoulders, is covered with a decorative plate consisting of three horizontal designs. At the top, over the base of the skull, a large torus of ivy leaves is bordered by cords; the ivy is gilded, though the cords are not. In the middle, a smooth and concave transitional zone corresponds to the hollow of the neck. At the bottom, an acanthus rinceau, or scroll, is interspersed with birds and butterflies. Portions of the bottom ornamentation are gilded, giving the helmet, with all its silver, gold, and iron components, a polychrome appearance. The ear guards encroach slightly on the bottom design, suggesting that it was not created specifically for the helmet.The face mask is made of iron, and covered with a sheet of silver. The central hinge from which it hangs is made of three parts: an iron tube welded to the interior head piece with an exterior silver tube, a notched silver tube fixed to the face mask that envelops the first part, and a pin which passes through both and has a silver knob at each end. The mask is shaped in the form of a human face. Holes are drilled between the lips and as nostrils; the eyes each have a narrow slit, with three holes in a trefoil design, two round holes outside and a heart-shaped hole in the middle, underneath each eye to allow for a greater range of vision. These apparently were not enough, for a small and rudimentary notch was carved into each of the heart-shaped holes to increase the wearer's vision. The mask is approximately 2 millimetres thick, of which the silver, which is folded around both the edges and each hole to hold it to the iron, accounts for between .25 and .5 millimetres.Distinctive features cover the face mask. The nose is long and fleshy with a prominent bump, and extends high between the eyes. The cheekbones are low yet prominent, and the small mouth, which droops toward the sinister side, shows a thick lower lip. Other features—the eyes and eyebrows, and the chin—are more conventional. The distinctive features suggest that the maker of the Emesa helmet attempted to translate some of the individual characteristics of the wearer's face into the helmet.
Output:
What is the name of the helmet given a polychrome appearance by portions of the gilded bottom ornamentation as well as all its silver, gold, and iron components?
