A crystal structure is the repetitive patterns in a mineral form. Cleavage is the ability of a mineral to break into flat surfaces. A fracture is a term used for an irregular way a mineral breaks apart.
Study of the mineral and the crystal structure.
- The underlying internal architecture of a crystalline substance, or its crystal structure, is expressed in a mineral's outward morphology. The three-dimensional regular (or ordered) arrangement of chemical units (atoms, ions, and anionic groups in inorganic materials; molecules in organic substances) that make up a crystal structure is reproduced in different ways via translational and symmetry operations and are referred to as motifs.
- The term "cleavage" describes the way some minerals fracture along specific structural lines of weakness. Mica is a wonderful example since it breaks along flat planes that are very closely spaced apart and produces thin "sheets."
- A mineral can fracture when it splits in an irregular pattern without any smooth, plane surfaces.

Answer:
"The New Colossus"
The lines from the passage which support the idea that the author is illustrating how "The New Colossus" is different from other statues from ancient history are:
Line 1: "Not like the brazen giant of Greek fame."
Lines 6 and 7: "Mother of Exiles" ... glows world-wide welcome."
Line 10: "Give me your tired ..."
Explanation:
These lines were written by Emma Lazarus in his poem titled "The New Colossus" (1883). It was a poem commissioned in order to raise funds for the pedestal of the Statue of Liberty. Lazarus noted that the Statue of Liberty was the "Mother of Exiles," thereby portraying The New Colossus as a welcoming symbol to all immigrants from all over the world.
