Mathematics QUESTION #1266

For \(f(x,y)=xy-2x\) on the triangular region with vertices \((0,0)\), \((4,0)\), \((0,4)\), the absolute minimum value is:

\(-8\)✔️
\(0\)
\(-4\)
\(4\)

Correct Answer Logic:

On boundary edge from \((0,0)\) to \((4,0)\) (\(y=0\)): \(f=-2x\), minimum at \(x=4\): \(f=-8\). Interior critical point: \(f_x=y-2=0\Rightarrow y=2\); \(f_y=x=0\Rightarrow x=0\), giving \(f(0,2)=0\). Checking all boundaries, the absolute minimum is \(-8\) at \((4,0)\).

Economics QUESTION #1708

Question 1144

Among the interrelated structural, agronomic, and environmental stressors confronting Pakistan's food system, which is increasingly regarded by food security analysts as the single most existential threat?

Highly skewed feudal land ownership patterns limiting smallholder productivity
Low agricultural factor productivity — in yields per hectare and water use efficiency
Intensifying climate-induced water stress, erratic monsoons, and glacial melt disrupting irrigation✔️
None of these

Correct Answer Logic:

While land inequity and low productivity are longstanding constraints, climate change and water scarcity have emerged as the most acute and growing threat to Pakistan's food security. Pakistan is among the world's most water-stressed nations (per capita water availability has fallen below 1,000 m³ — the scarcity threshold). Glacial lake outburst floods (GLOFs), irregular monsoons, and rising temperatures threaten both crop yields and irrigation supplies in the Indus Basin.
