LR Question 24 Explanation

QUESTION TEXT: Ditrama is a federation made up of three autonomous regions…

QUESTION TYPE: Must be True

FACTS:

Korva’s revenue share decreased even though its population increased.

ANALYSIS: It must be true that Korva’s share of the population decreased. At least one other region must have grown faster than Korva.

The number of inhabitants isn’t relevant since the revenues are based entirely on the percentage of total inhabitants in each reason. We have to compare the number to the number in each other region to see if the share should increase or decrease.

___________

1. The number is irrelevant. The only important factor is the rate of change in each region.
2. Previous years are irrelevant. We only care about the percentage of population in each region during the year in question.
3. This would make Korva lose revenue. It could be true. But it doesn’t have to be true. If one region grew by a very, very large amount then the revenue shares of the other two regions could both shrink.
4. It could be that one region grew by an incredibly large amount, Korva grew by a medium amount and the third region shrunk. Korva’s revenue will shrink but it did not have the smallest amount of growth.
5. CORRECT. Yes. We need at least one region to have had higher growth and increase its percentage share of the population enough to take away some from Korva.
