As technology​ advances, A. all opportunity costs increase. B. the PPF shifts outward. C. the PPF shifts inward because unemployment occurs. D. a country moves toward the midpoint along its PPF and can produce more of both goods. E. all opportunity costs decrease.

Answer 1

"Option B" is the correct answer to this question.

Explanation:

Technological progress involves the development of print head arrays and numerous carrying structures to covering a wider area of the tissue in one pass of the substratum. In this technology, an external shift of PPF implies, that even an economy can create all products more effectively, that's why other options were wrong, that can be described as follows:

• Option A, and Option E, is wrong because all opportunities can't increase or decrease the overall cost.
• In option C, In is wrong, because the PPF shift can't be inward.
• In option D, It is incorrect, because It can't move to the midpoint.
