Therefore, using GNI per capita alone disregards these important dimensions.

c) Lowering of the water table

[Solution Description] Groundwater overuse in agriculture can lead to several issues, but one significant consequence is the lowering of the water table.

Key Concept: Limitations of Averages

c) Assertion is true, but Reason is false.
[Solution Description] The assertion correctly points out one of the limitations of using average income as it can mask inequalities; if a few people earn significantly more than others, it may appear that everyone is well-off when they are not. However, the reason provided is misleading. While it is true that average income considers total income divided by population, this does not ensure an accurate picture of wealth distribution since it overlooks how income is spread among individuals.
