The juvenile literacy rate, number of adolescents per 100 who are literate, in Keating has risen forty percent over the previous three years ago. In Nickleby, the juvenile literacy rate has risen only twelve percent over the same time period. This data supports the conclusion that adolescents growing up in Keating are more likely to become literate than are adolescents growing up in Nickleby.
The argument above is flawed because it fails to take into account
A. how the juvenile population density of both Keating and Nickleby has changed over the past three years
B. what the juvenile literacy rates of Keating and Nickleby were three years ago
C. the change in the ratio of literate to illiterate juveniles three years ago and now in Keating and Nickleby
D. a comparison between the rate of juvenile population growth in Keating over the past three years and the corresponding rate in Nickleby
E. a comparison between expenditures on juvenile education made over the past three years in Keating and the same made in Nickleby

JLR is the number of adolescents who are literate per 100 literate population. Compared to three years ago, the JLR for keating has risen by 40% and for Nickleby has risen by 12%.
The data concludes, keating to be more literate than Nickleby.
A. how the juvenile population density of both Keating and Nickleby has changed over the past three years.
The population density is the number of persons living per square metre. So, we are not concerned with the population being clustered or scattered. This is irrelevant. Hence, wrong.
B. what the juvenile literacy rates of Keating and Nickleby were three years ago. This option clearly defines the base rates of the two regions in comparison. If the base rates are known then, the % increase can attribute to a definite figure. As the rates are per 100, we can use it for calculating the increase. Hence, correct answer.
C. the change in the ratio of literate to illiterate juveniles three years ago and now in Keating and Nickleby.
If we know the literate % , we can take the inverse to arrive at illiterate juveniles. So, it works vice versa. Hence, wrong.
D. a comparison between the rate of juvenile population growth in Keating over the past three years and the corresponding rate in Nickleby.
The year on year rate fluctuations is not needed to arrive at the conclusion. Hence, wrong.
E. a comparison between expenditures on juvenile education made over the past three years in Keating and the same made in Nickleby.
This is an irrelevant and completely out of scope answer. Hence, Wrong.
Option B
