India: Agriculture contributes 16% to GVA but employs 43% of the workforce, indicating disguised unemployment. The services sector dominates GVA (54%) with only 32% of the workforce.
China: A higher share of GVA comes from the industrial sector (41%), with a balanced workforce distribution in services and industry sectors.
Key Observation: India lags in industrialization compared to China, with a higher dependency on agriculture despite lower GVA contribution.
Draw a rough sketch for the curve $y = 2 + |x + 1|$. Using integration, find the area of the region bounded by the curve $y = 2 + |x + 1|$, $x = -4$, $x = 3$, and $y = 0$.
