Problem: After annexing the County of Portugal into one of the several counties that made up the Kingdom of Asturias, King Alfonso III of Asturias knighted Vimara Peres, in 868 AD, as the First Count of Portus Cale (Portugal). The region became known as Portucale, Portugale, and simultaneously Portugalia the County of Portugal. Later the Kingdom of Asturias was divided into a number of Christian Kingdoms in Northern Spain due to dynastic divisions of inheritance among the kings offspring. With the forced abdication of Alfonso III "the Great" of Asturias by his sons in 910, the Kingdom of Asturias split into three separate kingdoms of Leon, Galicia and Asturias. The three kingdoms were eventually reunited in 924 (Leon and Galicia in 914, Asturias later) under the crown of Leon.
In which year was Vimara Peres knighted?
The answer is the following: 868 AD

Problem: In 1965, Paul VI decided on the creation of a joint working group with the World Council of Churches to map all possible avenues of dialogue and cooperation. In the following three years, eight sessions were held which resulted in many joint proposals. It was proposed to work closely together in areas of social justice and development and Third World Issues such as hunger and poverty. On the religious side, it was agreed to share together in the Week of Prayer for Christian Unity, to be held every year. The joint working group was to prepare texts which were to be used by all Christians. On 19 July 1968, the meeting of the World Council of Churches took place in Uppsala, Sweden, which Pope Paul called a sign of the times. He sent his blessing in an ecumenical manner: "May the Lord bless everything you do for the case of Christian Unity." The World Council of Churches decided on including Catholic theologians in its committees, provided they have the backing of the Vatican.
In what year did the World Council of Churches meet in Uppsala, Sweden?
The answer is the following: 1968

Problem: The atolls have shown resilience to gradual sea-level rise, with atolls and reef islands being able to grow under current climate conditions by generating sufficient sand and coral debris that accumulates and gets dumped on the islands during cyclones. Gradual sea-level rise also allows for coral polyp activity to increase the reefs. However, if the increase in sea level occurs at faster rate as compared to coral growth, or if polyp activity is damaged by ocean acidification, then the resilience of the atolls and reef islands is less certain. The 2011 report of Pacific Climate Change Science Program of Australia concludes, in relation to Tuvalu, states the conclusions that over the course of the 21st century:
Where does sand and coral debris end up because of the action of cyclones?
The answer is the following: on the islands

Problem: The second main principle, sola fide (by faith alone), states that faith in Christ is sufficient alone for eternal salvation. Though argued from scripture, and hence logically consequent to sola scriptura, this is the guiding principle of the work of Luther and the later reformers. Because sola scriptura placed the Bible as the only source of teaching, sola fide epitomises the main thrust of the teaching the reformers wanted to get back to, namely the direct, close, personal connection between Christ and the believer, hence the reformers' contention that their work was Christocentric.
What did reformers considered their beliefs to be, in terms of focus?
The answer is the following:
Christocentric
