Problem: Dutch Republic:

In fact, there was an eighth province, the County of Drenthe, but this area was so poor it was exempt from paying federal taxes and as a consequence was denied representation in the States General. Each province was governed by the Provincial States, the main executive official (though not the official head of state) was a raadspensionaris. In times of war, the stadtholder, who commanded the army, would have more power than the raadspensionaris.

What was each raadspensionaris governed by?

Problem: In a tumbling pass, dismount or vault, landing is the final phase, following take off and flight This is a critical skill in terms of execution in competition scores, general performance, and injury occurrence. Without the necessary magnitude of energy dissipation during impact, the risk of sustaining injuries during somersaulting increases. These injuries commonly occur at the lower extremities such as: cartilage lesions, ligament tears, and bone bruises/fractures. To avoid such injuries, and to receive a high performance score, proper technique must be used by the gymnast. "The subsequent ground contact or impact landing phase must be achieved using a safe, aesthetic and well-executed double foot landing." A successful landing in gymnastics is classified as soft, meaning the knee and hip joints are at greater than 63 degrees of flexion.
In what kind of landing are the knee and hip joints at less than 63 degrees of flexion?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Sanskrit grammatical tradition, Vyakarana, one of the six Vedangas, began in the late Vedic period and culminated in the Astadhyayi of Panini, which consists of 3990 sutras (ca. fifth century BCE). About a century after Panini (around 400 BCE), Katyayana composed Vartikas on the Panini sutras. Patanjali, who lived three centuries after Panini, wrote the Mahabhasya, the "Great Commentary" on the Astadhyayi and Vartikas. Because of these three ancient Vyakaranins (grammarians), this grammar is called Trimuni Vyakarana. To understand the meaning of the sutras, Jayaditya and Vamana wrote a commentary, the Kasika, in 600 CE. Paninian grammar is based on 14 Shiva sutras (aphorisms), where the whole matrika (alphabet) is abbreviated. This abbreviation is called the Pratyahara.
What is the Sanskrit grammatical tradition?
A: Vyakarana

Question: However, William Woodthorpe Tarn, between World War I and World War II and the heyday of the League of Nations, focused on the issues of racial and cultural confrontation and the nature of colonial rule. Michael Rostovtzeff, who fled the Russian Revolution, concentrated predominantly on the rise of the capitalist bourgeoisie in areas of Greek rule. Arnaldo Momigliano, an Italian Jew who wrote before and after the Second World War, studied the problem of mutual understanding between races in the conquered areas. Moses Hadas portrayed an optimistic picture of synthesis of culture from the perspective of the 1950s, while Frank William Walbank in the 1960s and 1970s had a materialistic approach to the Hellenistic period, focusing mainly on class relations. Recently, however, papyrologist C. Preaux has concentrated predominantly on the economic system, interactions between kings and cities and provides a generally pessimistic view on the period. Peter Green, on the other hand, writes from the point of view of late 20th century liberalism, his focus being on individualism, the breakdown of convention, experiments and a postmodern disillusionment with all institutions and political processes.
Is there an answer to this question: Who studied the problem mutual understanding between races in conquered areas?

Answer: Arnaldo Momigliano

Problem: Cardinal (Catholicism):

In early times, the privilege of papal election was not reserved to the cardinals, and for centuries the person elected was customarily a Roman priest and never a bishop from elsewhere. To preserve apostolic succession the rite of consecrating him a bishop had to be performed by someone who was already a bishop. The rule remains that, if the person elected Pope is not yet a bishop, he is consecrated by the Dean of the College of Cardinals, the Cardinal Bishop of Ostia.

Why did the ceromony of consecrating a bishop have to be preformed by someone who was already a bishop?
---
A:
To preserve apostolic succession
