Outward Shift of the Production Possibility Curve Steps:

• An outward shift in the PPC occurs when a country's productive capacity increases due to more or better resources or technology.
• Better education improves worker skills and human capital, expanding maximum output: true.
• Higher investment adds to physical capital stock, allowing more production: true.
• Lower unemployment reduces idle labor, moving the economy from inside the PPC toward the frontier but not shifting the curve itself: false. Why D is correct:
• Not enough information; D is incomplete, but assuming it matches the true/true/false pattern, it aligns with PPC shift definition as changes in potential output, not utilization. Why the others are wrong:
• A: Wrongly labels better education as false, ignoring its role in enhancing productivity.
• B: Wrongly labels higher investment as false, overlooking capital's impact on capacity.
• C: Correctly identifies unemployment effect but listed as option; if D is equivalent, see above.

Final answer: C
