Problem: Some states distinguish between two levels: felonies and misdemeanors (minor crimes). Generally, most felony convictions result in lengthy prison sentences as well as subsequent probation, large fines, and orders to pay restitution directly to victims; while misdemeanors may lead to a year or less in jail and a substantial fine. To simplify the prosecution of traffic violations and other relatively minor crimes, some states have added a third level, infractions. These may result in fines and sometimes the loss of one's driver's license, but no jail time.
What are felonies?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The two became friends, and for many years lived in close proximity in Paris, Chopin at 38 Rue de la Chaussée-d'Antin, and Liszt at the Hôtel de France on the Rue Lafitte, a few blocks away. They performed together on seven occasions between 1833 and 1841. The first, on 2 April 1833, was at a benefit concert organized by Hector Berlioz for his bankrupt Shakespearean actress wife Harriet Smithson, during which they played George Onslow's Sonata in F minor for piano duet. Later joint appearances included a benefit concert for the Benevolent Association of Polish Ladies in Paris. Their last appearance together in public was for a charity concert conducted for the Beethoven Memorial in Bonn, held at the Salle Pleyel and the Paris Conservatory on 25 and 26 April 1841.
Who did the first concert of Chopin and Liszt benefit?
A: Harriet Smithson

Question: Vocalization markers indicating specific vowel sounds were introduced into the Arabic language by the end of the 9th century. The first Quranic manuscripts lacked these marks, therefore several recitations remain acceptable. The variation in readings of the text permitted by the nature of the defective vocalization led to an increase in the number of readings during the 10th century. The 10th-century Muslim scholar from Baghdad, Ibn Mujāhid, is famous for establishing seven acceptable textual readings of the Quran. He studied various readings and their trustworthiness and chose seven 8th-century readers from the cities of Mecca, Medina, Kufa, Basra and Damascus. Ibn Mujahid did not explain why he chose seven readers, rather than six or ten, but this may be related to a prophetic tradition (Muhammad's saying) reporting that the Quran had been revealed in seven "ahruf" (meaning seven letters or modes). Today, the most popular readings are those transmitted by Ḥafṣ (d.796) and Warsh (d. 812) which are according to two of Ibn Mujahid's reciters, Aasim ibn Abi al-Najud (Kufa, d. 745) and Nafi‘ al-Madani (Medina, d. 785), respectively. The influential standard Quran of Cairo (1924) uses an elaborate system of modified vowel-signs and a set of additional symbols for minute details and is based on ʻAsim's recitation, the 8th-century recitation of Kufa. This edition has become the standard for modern printings of the Quran.
Is there an answer to this question: Which recitation is the original basis of the Quran of Cairo?

Answer: ʻAsim's


Question: The influence of Old Norse certainly helped move English from a synthetic language along the continuum to a more analytic word order, and Old Norse most likely made a greater impact on the English language than any other language. The eagerness of Vikings in the Danelaw to communicate with their southern Anglo-Saxon neighbors produced a friction that led to the erosion of the complicated inflectional word-endings. Simeon Potter notes: “No less far-reaching was the influence of Scandinavian upon the inflexional endings of English in hastening that wearing away and leveling of grammatical forms which gradually spread from north to south. It was, after all, a salutary influence. The gain was greater than the loss. There was a gain in directness, in clarity, and in strength.”
Is there an answer to this question: Why did the Vikings stop using complicated word-endings?

Answer:
unanswerable
