The problem: Answer a question about this article:
The physics of quantum mechanics was thereby reduced to the mathematics of Hilbert spaces and linear operators acting on them. For example, the uncertainty principle, according to which the determination of the position of a particle prevents the determination of its momentum and vice versa, is translated into the non-commutativity of the two corresponding operators. This new mathematical formulation included as special cases the formulations of both Heisenberg and Schrödinger. When Heisenberg was informed von Neumann had clarified the difference between an unbounded operator that was a Self-adjoint operator and one that was merely symmetric, Heisenberg replied "Eh? What is the difference?"
What are the physics of quantum mechanics?
****
The answer: mathematics of Hilbert spaces and linear operators acting on them

In the Somali diaspora, multiple Islamic fundraising events are held every year in cities like Birmingham, London, Toronto and Minneapolis, where Somali scholars and professionals give lectures and answer questions from the audience. The purpose of these events is usually to raise money for new schools or universities in Somalia, to help Somalis that have suffered as a consequence of floods and/or droughts, or to gather funds for the creation of new mosques like the Abuubakar-As-Saddique Mosque, which is currently undergoing construction in the Twin cities.
Along with universities, the construction of what educational buildings are sometimes the focus of Islamic fundraising?

Caesar was assassinated on March 15, 44 BC. The assassination was led by Gaius Cassius and Marcus Brutus. Most of the conspirators were senators, who had a variety of economic, political, or personal motivations for carrying out the assassination. Many were afraid that Caesar would soon resurrect the monarchy and declare himself king. Others feared loss of property or prestige as Caesar carried out his land reforms in favor of the landless classes. Virtually all the conspirators fled the city after Caesar's death in fear of retaliation. The civil war that followed destroyed what was left of the Republic.
On what date was Caesar killed?
****
The answer: March 15, 44 BC


The problem: Answer a question about this article:
A party's floor leader, in conjunction with other party leaders, plays an influential role in the formulation of party policy and programs. He is instrumental in guiding legislation favored by his party through the House, or in resisting those programs of the other party that are considered undesirable by his own party. He is instrumental in devising and implementing his party's strategy on the floor with respect to promoting or opposing legislation. He is kept constantly informed as to the status of legislative business and as to the sentiment of his party respecting particular legislation under consideration. Such information is derived in part from the floor leader's contacts with his party's members serving on House committees, and with the members of the party's whip organization.
In what role are the floor leader's instrumental for legislation?
****
The answer:
guiding legislation favored by his party through the House, or in resisting those programs of the other party that are considered undesirable by his own party
