Answer:
c: to give his personal experience
Explanation:
"Specimen Days" presents a type of biography of the poet Whitman, focusing on the life of the poem during the American civil war and how he dealt with this period and with the later period.
This book seeks to mix historical events in the country with Whitman's life and personal experiences during those events. For this reason, when the book states that the poet was leaving an opera when he heard the news of the war, the book seeks to present a personal experience of his life.

In regard to goods or services a country cannot provide on its own, it may also simply be that it cannot provide those goods or services with the same degree of efficiency or quality as can another country. This is the idea of comparative advantage, where each country focuses on producing those things in which it has an advantage over others and then trade with others for the other goods or services it desires. On the global scale, this does increase productivity and prosperity overall.
