Here is a question about this article: 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.
What is the answer to this question: What government institution did Estonia continue to show desire in joining?
****
So... the Nordic Council


Here is a question about this article: Elevator doors protect riders from falling into the shaft. The most common configuration is to have two panels that meet in the middle, and slide open laterally. In a cascading telescopic configuration (potentially allowing wider entryways within limited space), the doors roll on independent tracks so that while open, they are tucked behind one another, and while closed, they form cascading layers on one side. This can be configured so that two sets of such cascading doors operate like the center opening doors described above, allowing for a very wide elevator cab. In less expensive installations the elevator can also use one large "slab" door: a single panel door the width of the doorway that opens to the left or right laterally. Some buildings have elevators with the single door on the shaft way, and double cascading doors on the cab.
What is the answer to this question: What design allows wider entryways within limited space?

So... a cascading telescopic configuration


Here is a question about this article: In 1999, the representatives of Lutheran World Federation and Catholic Church signed the Joint Declaration on the Doctrine of Justification, apparently resolving the conflict over the nature of justification which was at the root of the Protestant Reformation, although Confessional Lutherans reject this statement. This is understandable, since there is no compelling authority within them. On 18 July 2006, delegates to the World Methodist Conference voted unanimously to adopt the Joint Declaration.
What is the answer to this question: What two groups originally signed the Joint Declaration?

So...
Lutheran World Federation and Catholic Church
