Which effect limited astrolabe accuracy calculating sunrise time during the medieval era?

💡 Explanation

Manufacturing limitations impacted accuracy since astrolabes required precise component alignment, making accurate solar position calculation difficult. Therefore component alignment is the answer, rather than expansion, parallax, or refraction, which all require different mechanisms and are not the primary limiting factor for precision given the era.
