Input: Great power
The term "great power" was first used to represent the most important powers in Europe during the post-Napoleonic era. The "Great Powers" constituted the "Concert of Europe" and claimed the right to joint enforcement of the postwar treaties. The formalization of the division between small powers and great powers came about with the signing of the Treaty of Chaumont in 1814. Since then, the international balance of power has shifted numerous times, most dramatically during World War I and World War II. While some nations are widely considered to be great powers, there is no definitive list of them. In literature, alternative terms for great power are often world power or major power, but these terms can also be interchangeable with superpower.

Which treaty made the distinction of small powers and great powers a formal affair?
Output: Treaty of Chaumont

Input: Neptune
Neptune's dark spots are thought to occur in the troposphere at lower altitudes than the brighter cloud features, so they appear as holes in the upper cloud decks. As they are stable features that can persist for several months, they are thought to be vortex structures. Often associated with dark spots are brighter, persistent methane clouds that form around the tropopause layer. The persistence of companion clouds shows that some former dark spots may continue to exist as cyclones even though they are no longer visible as a dark feature. Dark spots may dissipate when they migrate too close to the equator or possibly through some other unknown mechanism.

What on Neptune are associated with dark spots that are brighter?
Output: methane clouds

Input: Near East
"Near East" remained popular in diplomatic, trade and journalistic circles, but a variation soon developed among the scholars and the men of the cloth and their associates: "the Nearer East," reverting to the classical and then more scholarly distinction of "nearer" and "farther." They undoubtedly saw a need to separate the Biblical lands from the terrain of the Ottoman Empire. The Christians saw the country as the land of the Old and New Testaments, where Christianity had developed. The scholars in the field of studies that eventually became Biblical archaeology attempted to define it on the basis of archaeology.

There was a need to separate what from the terrain of the Ottoman Empire?
Output:
the Biblical lands
