← HistoryWhich limitation arises when an astrolabe measures sunrise timing in a high-humidity environment?
A)Ecliptic ring deformation increases
B)Shadow pin misallignment error increases
C)Limb scale reading parallax increases✓
D)Alidade corrosion directly accelerates
💡 Explanation
Parallax error increases because condensation blurs the limb scale markings, degrading reading accuracy; therefore slight deviations appear larger. This outcome affects precise angle estimations rather than directly deforming rings or accelerating corrosion.
