← HistoryWhich navigational consequence arises when manipulating the instrument error in a sextant at sea?
A)Reduced accuracy of declination readings✓
B)Precise determination of Greenwich Mean Time
C)Compensating error minimizes solar parallax
D)Correcting instrument error mirrors horizon refraction
💡 Explanation
Altering adjustments affects declination readings because it changes the angle of the instrument in use; precise celestial observations are the Sextant's essential navigational mechanism. Therefore instrument error impacts declination negatively, rather than offering benefits like timekeeping or eliminating parallax.
