Oil Self-Sufficiency: Production vs. Consumption

Steps:

• Define self-sufficiency as a country's oil production equaling or exceeding its consumption.
• From the diagram, compare production bars to consumption bars for each country.
• Identify imbalances: excess production indicates surplus; deficit indicates reliance on imports.
• Select the statement matching Russia's deficit, where consumption surpasses production.

Why C is correct:

• Self-sufficiency requires production ≥ consumption; Russia's diagram shows production below consumption, confirming import dependence.

Why the others are wrong:

• A: Britain's production is positive but below consumption, so self-sufficiency is partial, not zero.
• B: Japan's production is far below consumption, lacking self-sufficiency.
• D: The US faces a deficit, but imports or efficiency measures address shortages beyond rationing.

Final answer: C
