Which risk increases when a 18th-century navigator sights the sun using a sextant with a warped index mirror?

💡 Explanation

When the index mirror is warped, reflection introduces systematic error because angles will be consistently skewed, regardless of the user skill. Therefore, systematic error occurs rather than random errors, visibility changes, or parallax effects, which have other causes.
