Problem: Mesozoic:

Compared to the vigorous convergent plate mountain-building of the late Paleozoic, Mesozoic tectonic deformation was comparatively mild. The sole major Mesozoic orogeny occurred in what is now the Arctic, creating the Innuitian orogeny, the Brooks Range, the Verkhoyansk and Cherskiy Ranges in Siberia, and the Khingan Mountains in Manchuria. This orogeny was related to the opening of the Arctic Ocean and subduction of the North China and Siberian cratons under the Pacific Ocean. Nevertheless, the era featured the dramatic rifting of the supercontinent Pangaea. Pangaea gradually split into a northern continent, Laurasia, and a southern continent, Gondwana. This created the passive continental margin that characterizes most of the Atlantic coastline (such as along the U.S. East Coast) today.

At what time was tectonic formation especially active?

Problem: Genocide:

The judges continue in paragraph 12, "The determination of when the targeted part is substantial enough to meet this requirement may involve a number of considerations. The numeric size of the targeted part of the group is the necessary and important starting point, though not in all cases the ending point of the inquiry. The number of individuals targeted should be evaluated not only in absolute terms, but also in relation to the overall size of the entire group. In addition to the numeric size of the targeted portion, its prominence within the group can be a useful consideration. If a specific part of the group is emblematic of the overall group, or is essential to its survival, that may support a finding that the part qualifies as substantial within the meaning of Article 4 [of the Tribunal's Statute]."

What is the key aspect of the targeted part of the group at the absolute term?

A: unanswerable


Problem: Premier League:

At the inception of the Premier League in 1992–93, just eleven players named in the starting line-ups for the first round of matches hailed from outside of the United Kingdom or Ireland. By 2000–01, the number of foreign players participating in the Premier League was 36 per cent of the total. In the 2004–05 season the figure had increased to 45 per cent. On 26 December 1999, Chelsea became the first Premier League side to field an entirely foreign starting line-up, and on 14 February 2005 Arsenal were the first to name a completely foreign 16-man squad for a match. By 2009, under 40% of the players in the Premier League were English.

How many players were from the UK or Ireland when the Premier League was created?

A: unanswerable


Problem: Napoleon:

Seeking national reconciliation between revolutionaries and Catholics, the Concordat of 1801 was signed on 15 July 1801 between Napoleon and Pope Pius VII. It solidified the Roman Catholic Church as the majority church of France and brought back most of its civil status. The hostility of devout Catholics against the state had now largely been resolved. It did not restore the vast church lands and endowments that had been seized during the revolution and sold off. As a part of the Concordat, he presented another set of laws called the Organic Articles.

The Concordat of 1801 strengthened the position of which church as the majority church of France?

the Roman Catholic Church
