Read the following passage carefully and choose the option that provides the most accurate and comprehensive summary of the central argument presented by the author. Ensure the chosen option captures the core logical progression without omitting essential nuances or introducing external information.

The classical economic theory of comparative advantage suggests that nations should specialize in producing goods where they hold a lower opportunity cost, thereby maximizing global efficiency through trade. However, this model often overlooks the strategic necessity of industrial complexity and the path dependency of economic development. Nations that specialize exclusively in low-skill primary commodities based on current comparative advantages may find themselves trapped in a low-growth equilibrium, as these sectors offer diminishing returns and fewer opportunities for technological spillover. Conversely, developing high-value manufacturing sectors, even if they initially appear to defy the principle of comparative advantage, can catalyze a sophisticated ecosystem of innovation and human capital. Ultimately, a nation's long-term prosperity is determined not by its ability to exploit static cost advantages, but by its capacity to transition toward high-complexity activities that foster structural transformation.

Options:

(A) While comparative advantage promotes immediate global efficiency, exclusive reliance on it for low-skill goods can hinder long-term growth by preventing the development of complex, innovation-driven industrial sectors.

(B) Classical economic models are fundamentally obsolete because they prioritize short-term trade efficiency over the environmental and social costs associated with primary commodity extraction in developing nations.

(C) Nations should ignore the principle of comparative advantage and focus entirely on high-value manufacturing to ensure they do not become trapped in low-growth equilibrium cycles caused by primary commodities.

(D) The prosperity of a nation is primarily a result of its ability to maintain low opportunity costs in primary sectors, which then provides the necessary capital to invest in future technological innovation and human capital.

Correct Answer: (A)

Detailed Breakdown:

Option A is correct: It captures the tension between the short-term efficiency of comparative advantage and the long-term strategic need for industrial complexity and structural transformation mentioned in the text.

Option B introduces external information: The passage discusses economic growth and industrial complexity, but it does not mention environmental or social costs as the reason for the model's limitations.

Option C is extreme: The passage suggests that the model overlooks strategic necessity and that nations should transition, but it does not go so far as to say nations should entirely ignore the principle in all contexts.

Option D is a distortion: The passage argues the opposite, stating that exclusive specialization in primary sectors can trap nations in low-growth rather than providing a path to innovation.

Test Prep Tip: Identify the relationship between the two main ideas in the passage. Here, the relationship is a contrast between static efficiency and dynamic growth. The correct summary must reflect this contrast rather than just focusing on one side.
