History

Which outcome occurs when an astrolabe's alidade rotates excessively during observation?

A)Parallax error reduces angular accuracy
B)Corrosion accelerates on brass components
C)Index slippage alters degree measurements
D)Gear meshing suffers increased wear

💡 Explanation

Parallax error causes reduced angular accuracy because incorrect alignment with the target increases with rotation; the observer's line of sight deviates from correct celestial position, therefore angular measurements are inaccurate; rather than mechanical failures.
