Factors of production: labor and enterprise shortages hinder infrastructure development

Steps:

• Recall four factors of production: land (natural resources), labor (human effort), capital (tools/infrastructure), enterprise (organization/innovation).
• Link poor infrastructure to insufficient capital and enterprise for building/maintaining it.
• Connect lack of civil engineers to labor shortage, as engineers provide skilled human input.
• Conclude that increasing labor (more engineers) and enterprise (better project organization) directly addresses both issues to unlock economic potential.

Why C is correct:

• Labor supplies skilled workers like civil engineers for infrastructure projects, while enterprise coordinates resources and innovation, aligning with the factors' definitions in economic theory.

Why the others are wrong:

• A: Capital aids infrastructure but ignores labor shortage; land is unrelated to the issues.
• B: Enterprise and capital help organization and tools but overlook the explicit lack of engineers (labor).
• D: Enterprise aids coordination but land scarcity isn't mentioned; labor shortage is unaddressed.

Final answer: C
