← HistoryWhich consequence results when an 18th-century quadrat fails in a mariner's quadrant during celestial navigation?
A)Inaccurate latitude determination occurs✓
B)Ship's magnetic compass loses alignment
C)Rudder responsiveness drastically decreases
D)Chronometer's timekeeping is significantly impaired
💡 Explanation
Inaccurate latitude determination happens due to parallax error increase when the quadrat warps; the reading uses *angular measurement*, because the quadrat’s angles become unreliable. Therefore, latitude becomes wrong, rather than compass issues or rudder failing.
