Problem: In 2005, Estonia joined the European Union's Nordic Battle Group. It has also shown continued interest in joining the Nordic Council. Whereas in 1992 Russia accounted for 92% of Estonia's international trade, today there is extensive economic interdependence between Estonia and its Nordic neighbours: three quarters of foreign investment in Estonia originates in the Nordic countries (principally Finland and Sweden), to which Estonia sends 42% of its exports (as compared to 6.5% going to Russia, 8.8% to Latvia, and 4.7% to Lithuania). On the other hand, the Estonian political system, its flat rate of income tax, and its non-welfare-state model distinguish it from the Nordic countries and their Nordic model, and indeed from many other European countries.
When did Estonia join the European Union's Nordic Battle Group?
The answer is the following: 2005

Problem: When the Emancipation Proclamation was announced, Tennessee was mostly held by Union forces. Thus, Tennessee was not among the states enumerated in the Proclamation, and the Proclamation did not free any slaves there. Nonetheless, enslaved African Americans escaped to Union lines to gain freedom without waiting for official action. Old and young, men, women and children camped near Union troops. Thousands of former slaves ended up fighting on the Union side, nearly 200,000 in total across the South.
Which edict freed slaves across most of the Confederacy, but technically not Tennessee?
The answer is the following: Emancipation Proclamation

Problem: The long-standing claim that the present uniform was first worn as mourning for the death of George III is unfounded. "Eton dress" has undergone significant changes since its standardisation in the 19th century. Originally (along with a top-hat and walking-cane), Etonian dress was reserved for formal occasions, but boys wear it today for classes, which are referred to as "divisions", or "divs". As stated above, King's Scholars wear a black gown over the top of their tailcoats, and occasionally a surplice in Chapel. Members of the teaching staff (known as Beaks) are required to wear a form of school dress when teaching.
What are classes at Eaton known as today?
The answer is the following: "divisions", or "divs"

Problem: Title IV of the 1978 Spanish constitution invests the Consentimiento Real (Royal Assent) and promulgation (publication) of laws with the monarch of Spain, while Title III, The Cortes Generales, Chapter 2, Drafting of Bills, outlines the method by which bills are passed. According to Article 91, within fifteen days of passage of a bill by the Cortes Generales, the sovereign shall give his or her assent and publish the new law. Article 92 invests the monarch with the right to call for a referendum, on the advice of the president of the government (commonly referred to in English as the prime minister) and the authorisation of the cortes.
Which article in the Spanish constitution gives the monarch the right to ask for a referendum?
The answer is the following:
