Professor Aurora Sinistra assigned her fifth-year students in 1995 a long and complex essay on Jupiter's moons. Ron Weasley erroneously wrote on his that Callisto was Jupiter's biggest moon and that wasn't Io the one with the volcanoes, while Harry Potter wrote that Europa is full of mice, instead of ice. Both essays were corrected by Hermione Granger before being delivered.^[1]
