Choose the most reasonable socio-economic causal chain, starting from demographic pressure and ending in outcomes. (i) Poverty (ii) Population (iii) Death (iv) Unemployment (v) Disease

Introduction / Context:
Logical chain questions in social studies ask for a plausible cause→effect progression. While real systems are complex, we select the most defensible linear path.

Given Data / Assumptions:

• Population growth increases job competition.
• Unemployment contributes to poverty.
• Poverty correlates with disease due to poor living conditions.
• Severe disease burdens elevate mortality risk.

Concept / Approach:
Prioritize causal plausibility: upstream demographic pressure, followed by economic effect, then health outcomes, then ultimate mortality.

Step-by-Step Solution:
1) (ii) Population pressure rises.2) (iv) Unemployment increases due to job scarcity.3) (i) Poverty results from joblessness.4) (v) Disease prevalence rises with deprivation.5) (iii) Death occurs as the terminal adverse outcome.

Verification / Alternative check:
Reversing any pair breaks causality (e.g., death cannot precede poverty/disease in a forward chain).

Why Other Options Are Wrong:
Sequences starting with death or disease as causes invert the chain; mixing poverty before unemployment confuses cause and effect.

Common Pitfalls:
Forgetting that real systems have feedback loops; here, we choose the simplest forward path as required by the item type.

Final Answer:
(ii), (iv), (i), (v), (iii)
