← HistoryWhich positional error increased for mariners without accurate chronometers because of accumulated inaccuracies?
A)Increased stellar parallax observation error
B)Worsening lunar distance estimation errors✓
C)Greater magnetic compass calibration drift
D)Increasing dead reckoning azimuth deviations
💡 Explanation
The error is lunar distance, increasing because inaccurate timekeeping causes errors calculating Greenwich Mean Time, which is essential for the lunar distance method; therefore, estimation errors increase rather than other errors from stellar or dead reckoning methods.
