Answer

Brief Explanations:

  1. An alloy is a mixture of metals or a metal and non - metal. So at least one element must be a metal.
  2. The English equivalent for youxia, ritters, chevaliers, and samurai is knight, which is a historical and cultural concept.
  3. Hematite has a red - brown streak despite its black appearance. This is a characteristic property in mineralogy.
  4. In "Childhood's End", Arthur Clarke calls the self - appointed rulers of Earth the Overlords.
  5. One order of magnitude is a factor of 10. A decrease of two orders of magnitude means dividing by 100, which is equivalent to multiplying by 0.01.

Answer:

  1. A metal
  2. Knight
  3. Red - brown
  4. The Overlords
  5. 0.01
