Problem: Russian language:

Judging by the historical records, by approximately 1000 AD the predominant ethnic group over much of modern European Russia, Ukraine and Belarus was the Eastern branch of the Slavs, speaking a closely related group of dialects. The political unification of this region into Kievan Rus' in about 880, from which modern Russia, Ukraine and Belarus trace their origins, established Old East Slavic as a literary and commercial language. It was soon followed by the adoption of Christianity in 988 and the introduction of the South Slavic Old Church Slavonic as the liturgical and official language. Borrowings and calques from Byzantine Greek began to enter the Old East Slavic and spoken dialects at this time, which in their turn modified the Old Church Slavonic as well.

When did Kievan Rus' adopt Christianity?
---
A: 988

Problem: Dwight D. Eisenhower:

The U.N. speech was well received but the Soviets never acted upon it, due to an overarching concern for the greater stockpiles of nuclear weapons in the U.S. arsenal. Indeed, Eisenhower embarked upon a greater reliance on the use of nuclear weapons, while reducing conventional forces, and with them the overall defense budget, a policy formulated as a result of Project Solarium and expressed in NSC 162/2. This approach became known as the "New Look", and was initiated with defense cuts in late 1953.

What was the policy of increasing nuclear weapons while decreasing conventional forces called?
---
A: New Look

Problem: Comprehensive school:

Germany has a comprehensive school known as the Gesamtschule. While some German schools such as the Gymnasium and the Realschule have rather strict entrance requirements, the Gesamtschule does not have such requirements. They offer college preparatory classes for the students who are doing well, general education classes for average students, and remedial courses for those who aren't doing that well. In most cases students attending a Gesamtschule may graduate with the Hauptschulabschluss, the Realschulabschluss or the Abitur depending on how well they did in school.

What type of school isn't the Gesamtschule?
---
A: unanswerable

Problem: Geography of the United States:

The Atlantic coast of the United States is low, with minor exceptions. The Appalachian Highland owes its oblique northeast-southwest trend to crustal deformations which in very early geological time gave a beginning to what later came to be the Appalachian mountain system. This system had its climax of deformation so long ago (probably in Permian time) that it has since then been very generally reduced to moderate or low relief. It owes its present-day altitude either to renewed elevations along the earlier lines or to the survival of the most resistant rocks as residual mountains. The oblique trend of this coast would be even more pronounced but for a comparatively modern crustal movement, causing a depression in the northeast resulting in an encroachment of the sea upon the land. Additionally, the southeastern section has undergone an elevation resulting in the advance of the land upon the sea.

During what geological. That the Appalachian Mountains reach their lowest point
