Which navigational error increases during a 1760s voyage with sextants in conditions of variable cloud cover?

💡 Explanation

Variable cloud cover restricts celestial observations; therefore, sextant's angle precision degrades via obstruction, because intermittent viewing prevents accurate altitude sightings, rather than navigation being affected by timing or magnetic anomalies in the 1700s.
