GMATNinja can you please help resolve the doubt...I do feel the Answer is A.

Information: - In our society, the teacher-student ratio was 1:50 back in 1978. Today the ratio is 1:100.
Premise- The total student population has increased significantly over the past 30 years.
What can be the most appropriate conclusion?


Option A says
A. Increase in the number of students caused this situation.

And Option D says- Both increase in the number of students and proportionately less increase in the number of teachers caused this situation.

If number of teachers also increase in the same proportion, then the ratio will still be 1:50. The argument will be incomplete. If we say students increased a lot more than the number of teachers, only then we can arrive at a proper conclusion.

So Option D is a better Conclusion

Why i chose D over B ( & A)?

Let's say in 1978 there were 50 students, therefore according to the ratio there would be 1 teacher.
Now in 2008, the ratio is 1:100 so let's assume that there are 200 students therefore there would be 2 teachers ( 2:200)

A. Increase in the number of students caused this situation- sure it did but this doesn't say anything about the teachers

I was between B and D eventually chose D, but here's why i did not pick B:

B. Proportionately less increase in the number of teachers was responsible for the situation.

Same reasoning as why A is not the answer, B only talks about teachers.

D. Both increase in the number of students and proportionately less increase in the number of teachers caused this situation.

This addresses both the increase in students and proportionately less increase in the number of teachers ( 1: 50 @ 1978 --> 1: 100 2008 ( 2:200))

D looks good, but what if the number of teaches remains steady or increases just a bit much less in comparison to student increase , could that still provides us with the same ratio of 1:100.

In our society, the teacher-student ratio was 1:50 back in 1978. Today the ratio is 1:100. The total student population has increased significantly over the past 30 years.

Which conclusion can you draw from the above statement?

A. Increase in the number of students caused this situation.
B. Proportionately less increase in the number of teachers was responsible for the situation.
C. Not many new educational institutions came up during the period.
D. Both increase in the number of students and proportionately less increase in the number of teachers caused this situation.
E. Poor teaching method was responsible for this situation.

I think definitely all of the above, but also, not enough exposure to other educational departments. There are a lot of different options for professions and careers that a lot of people don't think about because it is not so lucrative. I know that this may sound a bit weird but, how many people out there want to work in restoration technology? Metallurgy? I don't think I ever met someone who said he works in restorative arts for example. I know maybe these professions are not so in demand anymore and I guess everybody's going more deeply into tech and business.
