The problem: Answer a question about this article:
The Mongol prince Godan, a grandson of Genghis Khan, raided as far as Lhasa. During his attack in 1240, Prince Godan summoned Sakya Pandita (11821251), leader of the Sakya school of Tibetan Buddhism, to his court in what is now Gansu in Western China. With Sakya Pandita's submission to Godan in 1247, Tibet was officially incorporated into the Mongol Empire during the regency of Toregene Khatun (12411246). Michael C. van Walt van Praag writes that Godan granted Sakya Pandita temporal authority over a still politically fragmented Tibet, stating that "this investiture had little real impact" but it was significant in that it established the unique "Priest-Patron" relationship between the Mongols and the Sakya lamas.
Who was the regent of the Mongol Empire?
****
The answer: Toregene Khatun

Like all the Romance languages, Catalan verbal inflection is more complex than the nominal. Suffixation is omnipresent, whereas morphological alternations play a secondary role. Vowel alternances are active, as well as infixation and suppletion. However, these are not as productive as in Spanish, and are mostly restricted to irregular verbs.
What plays a secondary part in Catalan?
****
The answer: morphological alternations

The problem: Answer a question about this article:
Asphalt/bitumen can sometimes be confused with "coal tar", which is a visually similar black, thermoplastic material produced by the destructive distillation of coal. During the early and mid-20th century when town gas was produced, coal tar was a readily available byproduct and extensively used as the binder for road aggregates. The addition of tar to macadam roads led to the word tarmac, which is now used in common parlance to refer to road-making materials. However, since the 1970s, when natural gas succeeded town gas, asphalt/bitumen has completely overtaken the use of coal tar in these applications. Other examples of this confusion include the La Brea Tar Pits and the Canadian oil sands, both of which actually contain natural bitumen rather than tar. Pitch is another term sometimes used at times to refer to asphalt/bitumen, as in Pitch Lake.
For what was coal tar used in road paving?
****
The answer: binder

In the Ottoman Empire, these ideological reforms did not take place and these views did not integrate into common thought until much later. As well, there was no spread of this doctrine within the New World and the advanced civilizations of the Aztec, Maya, Inca, Mohican, Delaware, Huron and especially the Iroquois. The Iroquois philosophy in particular gave much to Christian thought of the time and in many cases actually inspired some of the institutions adopted in the United States: for example, Benjamin Franklin was a great admirer of some of the methods of the Iroquois Confederacy, and much of early American literature emphasized the political philosophy of the natives.
Who was a great admirer of some of the methods of the Iroquois Confederacy?
****
The answer:
Benjamin Franklin
