Fact 1: Elementary school teachers are struggling to provide individualized attention to their students: the proportion of students in a class that the teachers can recall the grades of is decreasing.
Fact 2. Elementary school teachers recall the grades of the lowest ranked and highest ranked students in their classes far better than they recall the grades of the students who fall in the middle ranks.
Fact 2 would be most likely to contribute to an explanation of fact 1 if which of the following were also true?
A. The average elementary school teacher currently recalls fewer than half the grades of middle ranked students.
B. The average duration of elementary school classes is decreasing.
C. The average number of students in a class is increasing.
D. The average number of classes taken by an elementary school teacher is increasing.
E. The average number of hours that elementary school teachers spend in grading is decreasing.

Fact 1: Elementary school teachers are finding hard to provide individual attention to their students. The reasons can be manifold - lack of interest among teachers, excessive work load, health issues, personal problems at home etc.
The author cites an example to validate the fact - the proportion of students that teachers can recall is decreasing.
Which means the teachers earlier had been recalling more grades , and eventually providing individual attention to their students. But, something has changed recently, which must the reason behind the transition.
Fact 2: Those who support the teachers say that , the teachers are effective in recalling the highest and lowest marks of the class, but not the middle lot of students. This clearly illustrates that the teacher is recalling a few sections of the students, but not the entire class. We can also infer that, the top and bottom section occupy a lesser proportion compared to the middle section.
If fact 2 is most likely contributing to fact 1, which of the options must be true.
A. The average elementary school teacher currently recalls fewer than half the grades of middle ranked students.
If this has happened, then we can clearly say that the teacher is most recalling. If we assume the top and bottom students to be 20%, which the teacher is recalling. And lesser than half can be less than 80%/2 = less than 40%. So, the recall proportion can be anywhere between 60% and 21%. So, we cannot conclusively say anything that this option acts as link between fact 2 abs fact 1.
B. The average duration of elementary school classes is decreasing.
The duration of the classes is irrelevant to the context. Is the duration decreasing now, or has been the same? If that’s the case, then the decline in recall cannot be explained. Hence, Wrong.
C. The average number of students in a class is increasing.If the average number of students in the class is increasing, which means the net number of students adding each year has been increasing. This has lead to more students within the classroom, making the recall rates to decline each year. Hence, correct.
D. The average number of classes taken by an elementary school teacher is increasing.
The issue is not with respect to the school in general, but to a class and that too the decline in recall rates for the teacher. Hence, wrong.
E. The average number of hours that elementary school teachers spend in grading is decreasing.
This option puts the blame on the workload given, so that the teacher is less timed for the regular classes , hence not able to recall. This is irrelevant and entirely out of context. Hence wrong.
Option C
