Despite the fact that River City increased the average class size by m

Question

Despite the fact that River City increased the average class size by more than 15% in all grades two years ago, this year’s average SAT scores for the junior class were the highest ever. This shows that class size is not a good determinant of student performance. Consequently, other school districts should follow River City’s lead and save money by increasing the size of their classes. Each of the following statements, if true, is a valid objection to this argument  EXCEPT : ​

A) The advantages of smaller classes are more pronounced in elementary school than in high school. ​
B) The number of classroom discipline problems reported by teachers is directly proportional to the number of students in the classroom. ​
C) Japanese schools have a lower teacher-to-student ratio than American schools do and have generally better results on international standardized tests. ​
D) Three years ago, the eighth graders in River City Middle School had very high scores on their standardized tests. ​
E) The effects on students of learning in larger classes take at least three or four years to manifest themselves completely.

D basically provides an alternative explanation for the highest SAT scores result. Eight graders three years ago are juniors this year. Therefore if they had high scores on standardizes tests three years ago then it is possible that they have the highest SAT score because they are smart.
E says that the effect of increasing class size need AT LEAST 3 years to manifest while River City just increased the average class size 2 years ago. Thus the highest SAT scores cannot be a result of the increase in class size.

Despite the fact that River City increased the average class size by more than 15% in all grades two years ago, this year’s average SAT scores for the junior class were the highest ever. This shows that class size is not a good determinant of student performance. Consequently, other school districts should follow River City’s lead and save money by increasing the size of their classes. Each of the following statements, if true, is a valid objection to this argument EXCEPT: ​

A) The advantages of smaller classes are more pronounced in elementary school than in high school.
 ​ This shows that smaller class is better than large class and hence other school should not follow River city. 
B) The number of classroom discipline problems reported by teachers is directly proportional to the number of students in the classroom.
  ​Other school should no increase class size as more students lead to more problems. 
C) Japanese schools have a lower teacher-to-student ratio than American schools do and have generally better results on international standardized tests.
  Assume that Japan has more students than America, in terms of class, and has equal number of teachers then the condition here will be true. But more students are leading to better results. So, its not an objection but supports the argument. 
D) Three years ago, the eighth graders in River City Middle School had very high scores on their standardized tests. ​
 Three years ago, the number of students was less and hence other schools should not increase class size. 
E) The effects on students of learning in larger classes take at least three or four years to manifest themselves completely. 
 Again larger classes are not good.
