Read the excerpt from "Ship's Chronometer from HMS Beagle." Our object is one of those lower-cost chronometers, made in 1800 by Thomas Earnshaw. It is made of brass and is around the size of a large pocket watch, with a normal clock dial showing roman numerals and a smaller dial at the bottom for the second hand. The clock is suspended inside a swivelling brass ring fitted to the inside of a wooden box – this is the key to keeping the chronometer level even in an unsteady ship. Which details from the excerpt help readers visualize the chronometer? Select 3 options.
