Explain the primary difference between absolute poverty and relative poverty.

(a) Describe the relationship between the Lorenz curve and the line of perfect equality.
(b) If the area between the line of perfect equality and the Lorenz curve is represented by \( A \), and the area beneath the Lorenz curve is represented by \( B \), state the formula for the Gini coefficient and explain what a coefficient of \( 0 \) would represent.
