Question

what reason best explains why the union won?
better military generals
greater manpower and industrial resources
fighting a defensive war

Explanation:

Analyze military leadership

The Confederacy initially possessed highly capable and experienced military commanders, such as Robert E. Lee, meaning superior generals was not the primary Union advantage.

Evaluate defensive strategy

The Confederacy, not the Union, primarily fought a defensive war on its own territory, making this option historically inaccurate for the Union.

Assess material and human resources

The Union possessed a vastly larger population, an extensive railroad network, and the overwhelming majority of the nation's industrial manufacturing capacity, which ultimately allowed it to sustain a prolonged total war.

Answer:

• Better military generals
• Greater manpower and industrial resources (Correct answer)
• Fighting a defensive war
