Which error increases when an astrolabe's altitude scale markings are unevenly spaced due to manufacturing variations?

💡 Explanation

When altitude scale markings are uneven, inaccurate angular measurements occur because the altitude readings are direct inputs for latitude calculations, leading to errors in geographic positioning. Therefore latitude determination becomes inaccurate, rather than affecting parallax, timekeeping, or deformation, which depend on different aspects of the instrument.
