Question

chron = \time\, geo = \earth\, graph = \write\, meter = \measure\. which word most likely means \a timepiece fitted with a recording device that marks down exact intervals of time\? geometric, geographic, chronometer, chronograph

Explanation:

The prefix "chron -" means "time". "Graph" means "write". A chronograph is a time - piece with a recording device that marks down exact intervals of time. "Geometric" relates to geometry, "geographic" to the earth, and "chronometer" is just a time - measuring device without the writing/recording aspect.

Answer:

chronograph
