Problem: Cardinal (Catholicism):

When in choir dress, a Latin-rite cardinal wears scarlet garments the blood-like red symbolizes a cardinal's willingness to die for his faith. Excluding the rochet which is always white the scarlet garments include the cassock, mozzetta, and biretta (over the usual scarlet zucchetto). The biretta of a cardinal is distinctive not merely for its scarlet color, but also for the fact that it does not have a pompon or tassel on the top as do the birettas of other prelates. Until the 1460s, it was customary for cardinals to wear a violet or blue cape unless granted the privilege of wearing red when acting on papal business. His normal-wear cassock is black but has scarlet piping and a scarlet fascia (sash). Occasionally, a cardinal wears a scarlet ferraiolo which is a cape worn over the shoulders, tied at the neck in a bow by narrow strips of cloth in the front, without any 'trim' or piping on it. It is because of the scarlet color of cardinals' vesture that the bird of the same name has become known as such.[citation needed]

Problem: In 2014 the Notre Dame student body consisted of 12,179 students, with 8,448 undergraduates, 2,138 graduate and professional and 1,593 professional (Law, M.Div., Business, M.Ed.) students. Around 2124% of students are children of alumni, and although 37% of students come from the Midwestern United States, the student body represents all 50 states and 100 countries. As of March 2007[update] The Princeton Review ranked the school as the fifth highest 'dream school' for parents to send their children. As of March 2015[update] The Princeton Review ranked Notre Dame as the ninth highest. The school has been previously criticized for its lack of diversity, and The Princeton Review ranks the university highly among schools at which "Alternative Lifestyles [are] Not an Alternative." It has also been commended by some diversity oriented publications; Hispanic Magazine in 2004 ranked the university ninth on its list of the top25 colleges for Latinos, and The Journal of Blacks in Higher Education recognized the university in 2006 for raising enrollment of African-American students. With 6,000 participants, the university's intramural sports program was named in 2004 by Sports Illustrated as the best program in the country, while in 2007 The Princeton Review named it as the top school where "Everyone Plays Intramural Sports." The annual Bookstore Basketball tournament is the largest outdoor five-on-five tournament in the world with over 700 teams participating each year, while the Notre Dame Men's Boxing Club hosts the annual Bengal Bouts tournament that raises money for the Holy Cross Missions in Bangladesh.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
After the assassination of Uthman in 656, Ali, a member of the Quraysh tribe and the cousin and son-in-law of Muhammad, was elected as the caliph. He soon met with resistance from several factions, owing to his relative political inexperience. Ali moved his capital from Medina to Kufa. The resulting conflict, which lasted from 656 until 661, is known as the First Fitna ("civil war"). Muawiyah I, the governor of Syria, a relative of Uthman ibn al-Affan and Marwan I, wanted the culprits arrested. Marwan I manipulated everyone and created conflict. Aisha, the wife of Muhammad, and Talhah and Al-Zubayr, two of the companions of Muhammad, went to Basra to tell Ali to arrest the culprits who murdered Uthman. Marwan I and other people who wanted conflict manipulated everyone to fight. The two sides clashed at the Battle of the Camel in 656, where Ali won a decisive victory.
When was Uthman born?
A: unanswerable

Context and question: Like any plucked instrument, mandolin notes decay to silence rather than sound out continuously as with a bowed note on a violin, and mandolin notes decay faster than larger stringed instruments like the guitar. This encourages the use of tremolo (rapid picking of one or more pairs of strings) to create sustained notes or chords. The mandolin's paired strings facilitate this technique: the plectrum (pick) strikes each of a pair of strings alternately, providing a more full and continuous sound than a single string would.
What is a slectrum?
Answer: unanswerable

Question: Writing to a friend in May 1795, Burke surveyed the causes of discontent: "I think I can hardly overrate the malignity of the principles of Protestant ascendency, as they affect Ireland; or of Indianism [i.e. corporate tyranny, as practiced by the British East Indies Company], as they affect these countries, and as they affect Asia; or of Jacobinism, as they affect all Europe, and the state of human society itself. The last is the greatest evil". By March 1796, however Burke had changed his mind: "Our Government and our Laws are beset by two different Enemies, which are sapping its foundations, Indianism, and Jacobinism. In some Cases they act separately, in some they act in conjunction: But of this I am sure; that the first is the worst by far, and the hardest to deal with; and for this amongst other reasons, that it weakens discredits, and ruins that force, which ought to be employed with the greatest Credit and Energy against the other; and that it furnishes Jacobinism with its strongest arms against all formal Government".
Is there an answer to this question: Burke never changed his mind on which ideology, which he called "the greatest evil"?

Answer: unanswerable

Problem: Age of Enlightenment:

In England, the Royal Society of London also played a significant role in the public sphere and the spread of Enlightenment ideas. It was founded by a group of independent scientists and given a royal charter in 1662. The Society played a large role in spreading Robert Boyle's experimental philosophy around Europe, and acted as a clearinghouse for intellectual correspondence and exchange. Boyle was "a founder of the experimental world in which scientists now live and operate," and his method based knowledge on experimentation, which had to be witnessed to provide proper empirical legitimacy. This is where the Royal Society came into play: witnessing had to be a "collective act", and the Royal Society's assembly rooms were ideal locations for relatively public demonstrations. However, not just any witness was considered to be credible; "Oxford professors were accounted more reliable witnesses than Oxfordshire peasants." Two factors were taken into account: a witness's knowledge in the area; and a witness's "moral constitution". In other words, only civil society were considered for Boyle's public.
