PROBLEM: Passage: After a new wave of UN sanctions, on 11 March 2013, North Korea claimed that it had invalidated the 1953 armistice. On 13 March 2013, North Korea confirmed it ended the 1953 Armistice and declared North Korea "is not restrained by the North-South declaration on non-aggression". On 30 March 2013, North Korea stated that it had entered a "state of war" with South Korea and declared that "The long-standing situation of the Korean peninsula being neither at peace nor at war is finally over". Speaking on 4 April 2013, the U.S. Secretary of Defense, Chuck Hagel, informed the press that Pyongyang had "formally informed" the Pentagon that it had "ratified" the potential usage of a nuclear weapon against South Korea, Japan and the United States of America, including Guam and Hawaii. Hagel also stated that the United States would deploy the Terminal High Altitude Area Defense anti-ballistic missile system to Guam, because of a credible and realistic nuclear threat from North Korea. Question: How does the United States view North Korea's threats?

SOLUTION: credible and realistic nuclear threat

PROBLEM: Passage: The primary objective of the European Central Bank, as laid down in Article 127(1) of the Treaty on the Functioning of the European Union, is to maintain price stability within the Eurozone. The Governing Council in October 1998 defined price stability as inflation of under 2%, "a year-on-year increase in the Harmonised Index of Consumer Prices (HICP) for the euro area of below 2%" and added that price stability "was to be maintained over the medium term". (Harmonised Index of Consumer Prices) Unlike for example the United States Federal Reserve Bank, the ECB has only one primary objective but this objective has never been defined in statutory law, and the HICP target can be termed ad-hoc. Question: What did the Harmonised Index of Consumer Prices state that price stability had to be maintained at?

SOLUTION: over the medium term

PROBLEM: Passage: Oskar Luts was the most prominent prose writer of the early Estonian literature, who is still widely read today, especially his lyrical school novel Kevade (Spring).
