The Ho Chi Minh Trail was a network of jungle paths used to supply the Viet Cong. Through which countries did it primarily run?

• A. Vietnam and Cambodia
• B. Laos and Cambodia
• C. Thailand and Vietnam
• D. China and Laos

Answer: (B)

The key idea here is understanding how North Vietnam kept its war effort going by moving supplies and troops through nearby countries to avoid heavy bombing in Vietnam itself. The Ho Chi Minh Trail was a covert network that snaked from North Vietnam down into South Vietnam, using routes across neighboring countries to stay out of reach of major Allied air campaigns. The heart of these supply lines ran through Laos and Cambodia, with numerous branches threading through the eastern parts of Laos and into Cambodia before crossing into South Vietnam. This geography provided safer corridors, terrain camouflage, and sanctuary areas that made sustained movement of weapons, fuel, and food possible despite intense bombardment in Vietnam proper. While some activity did touch other areas or border regions, the primary legs of the trail were in Laos and Cambodia, making that pairing the best answer.
