OE


A “quantum” is “the smallest amount that can exist independently” and is a perfect fit for blank (i). “Plethora” means a large amount of something, which is the opposite of what the clue suggests, and “parameter” is a boundary. For blank (ii), a “mote” is a speck or small amount; the word is specifically associated with dust. “Trove” means a collection of valuable things and “covey” means a small group of things. In blank (iii), since the definition is “based only on size and state of matter rather than on structure,” it is “loose,” rather than strict or “precise.” Nowhere in the sentence is it suggested that this definition is “deleterious,” meaning causing harm
