If teenagers read for too long, myopia is almost inevitable. Students at Jinghua Middle School study hard. Although everyone knows how to protect their eyes, most students spend more than 10 hours a day reading. As a result, continuous reading time is too long. The remaining students read 8 hours a day. The teacher in charge of the class praises the students who read more than 10 hours a day. If the above statement is true, which of the following conclusions can best be reached? ['None of the students at A. Jinghua Middle School has normal vision and everyone wears myopia.', 'Students who do not read more than 10 hours a day study hard.', 'The percentage of myopia in Jinghua Middle School students is greater than in other schools.', 'Most of the students praised by the class teacher are myopia.']
