History

Which outcome arises in early navigational astrolabes from accumulating parallax error?

A)Inaccurate timekeeping during voyages
B)Distorted star altitude measurements
C)Unreliable celestial object identification
D)Excessive instrument weight and drift

💡 Explanation

Distorted measurements occur with increased parallax because larger viewing angles cause errors when aligning stars via the alidade, therefore altitude readings are affected, rather than merely timekeeping or identification issues, given systematic misalignment during sightings.
