History

Which limit reduces accuracy using 18th-century marine box sextants?

A)Ship's deck instability dominates error
B)Atmospheric refraction induces larger errors
C)Chronometer precision greatly limits accuracy
D)Telescope magnification hampers targeting precise stars

💡 Explanation

Ship deck pitching/rolling causes sextant reading errors because INERTIAL ERROR introduces observational imprecision; therefore, a steady platform gives better readings rather than other issues given optimal observers and equipment.
