← HistoryWhich consequence resulted when early 18th-century sextants experienced thermal expansion within their brass arc?
A)Decreased observer measurement parallax
B)Increased systematic altitude measurement errors✓
C)Minimized horizon line refraction errors
D)Improved celestial body targeting precision
💡 Explanation
Increased systematic altitude measurement errors resulted, because thermal expansion altered angle measurements on the sextant's arc (Thermal Expansion), impacting navigation precision; therefore, compensation methods were critical, rather than improving precision directly.
