Step 1: Identify the core economic problems.
Economies globally grapple with three fundamental issues stemming from resource scarcity:
What to produce? – This involves determining which goods and services to create and in what quantities.
How to produce? – This concerns the selection of production methods (e.g., labor-intensive versus capital-intensive).
For whom to produce? – This addresses the distribution of produced goods and services across societal segments.
Step 2: Apply the concepts to the scenario.
The current decision involves prioritizing the production of either education and health services or military services. This directly relates to the allocation of limited resources between distinct categories of output.
Step 3: Discard irrelevant options.
- Option (A) How to produce? → Pertains to production methods, which is not the focus here.
- Option (C) Whom to produce? → Deals with distribution among individuals, which is not the primary issue in this context.
- Option (D) Where to produce? → This is not considered a fundamental economic problem.
Step 4: Determine the solution.
The economic problem being addressed is unequivocally What to produce?
Final Answer: \[\boxed{\text{What to produce?}}\]
