Problem: 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 did Eisenhower reduce as he increased nuclear weapons stockpiles?

Answer: conventional forces

Problem: Traditionally, Switzerland avoids alliances that might entail military, political, or direct economic action and has been neutral since the end of its expansion in 1515. Its policy of neutrality was internationally recognised at the Congress of Vienna in 1815. Only in 2002 did Switzerland become a full member of the United Nations and it was the first state to join it by referendum. Switzerland maintains diplomatic relations with almost all countries and historically has served as an intermediary between other states. Switzerland is not a member of the European Union; the Swiss people have consistently rejected membership since the early 1990s. However, Switzerland does participate in the Schengen Area.
What have the Swiss people continually rejected membership in since the 1990's?
---
Answer: European Union

Problem: After 539 Ravenna was reconquered by the Romans in the form of the Eastern Roman Empire (Byzantine Empire) and became the seat of the Exarchate of Ravenna. The greatest development of Christian mosaics unfolded in the second half of the 6th century. Outstanding examples of Byzantine mosaic art are the later phase mosaics in the Basilica of San Vitale and Basilica of Sant'Apollinare Nuovo. The mosaic depicting Emperor Saint Justinian I and Empress Theodora in the Basilica of San Vitale were executed shortly after the Byzantine conquest. The mosaics of the Basilica of Sant'Apollinare in Classe were made around 549. The anti-Arian theme is obvious in the apse mosaic of San Michele in Affricisco, executed in 545547 (largely destroyed; the remains in Berlin).
When did the biggest achievement in Christian mosaics take place?

Answer:
the second half of the 6th century
