Input: Read this: The first British patent for the use of asphalt/bitumen was 'Cassell's patent asphalte or bitumen' in 1834. Then on 25 November 1837, Richard Tappin Claridge patented the use of Seyssel asphalt (patent #7849), for use in asphalte pavement, having seen it employed in France and Belgium when visiting with Frederick Walter Simms, who worked with him on the introduction of asphalt to Britain. Dr T. Lamb Phipson writes that his father, Samuel Ryland Phipson, a friend of Claridge, was also "instrumental in introducing the asphalte pavement (in 1836)". Indeed, mastic pavements had been previously employed at Vauxhall by a competitor of Claridge, but without success.
Question: In what year was Cassell's patent France or Belgium issued?

QUES: Historically home to the Kumeyaay people, San Diego was the first site visited by Europeans on what is now the West Coast of the United States. Upon landing in San Diego Bay in 1542, Juan Rodríguez Cabrillo claimed the entire area for Spain, forming the basis for the settlement of Alta California 200 years later. The Presidio and Mission San Diego de Alcalá, founded in 1769, formed the first European settlement in what is now California. In 1821, San Diego became part of the newly-independent Mexico, which reformed as the First Mexican Republic two years later. In 1850, it became part of the United States following the Mexican–American War and the admission of California to the union.

In what year didn't San Diego become part of the United States?
What is the answer?

QUES: There is no scale factor band 21 (sfb21) for frequencies above approx 16 kHz, forcing the encoder to choose between less accurate representation in band 21 or less efficient storage in all bands below band 21, the latter resulting in wasted bitrate in VBR encoding.
What is the maximum frequency that scale factor band 21 can go up to?

ANS: 16 kHz


On 18 January 2014, the interim government instituted a new constitution following a referendum in which 98.1% of voters were supportive. Participation was low with only 38.6% of registered voters participating although this was higher than the 33% who voted in a referendum during Morsi's tenure. On 26 March 2014 Abdel Fattah el-Sisi the head of the Egyptian Armed Forces, who at this time was in control of the country, resigned from the military, announcing he would stand as a candidate in the 2014 presidential election. The poll, held between 26 and 28 May 2014, resulted in a landslide victory for el-Sisi. Sisi was sworn into office as President of Egypt on 8 June 2014. The Muslim Brotherhood and some liberal and secular activist groups boycotted the vote. Even though the military-backed authorities extended voting to a third day, the 46% turnout was lower than the 52% turnout in the 2012 election.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the support by voters for referendum?
Ah, so.. 98.1%


Question: The National Incident Based Reporting System (NIBRS) crime statistics system aims to address limitations inherent in UCR data. The system is used by law enforcement agencies in the United States for collecting and reporting data on crimes. Local, state, and federal agencies generate NIBRS data from their records management systems. Data is collected on every incident and arrest in the Group A offense category. The Group A offenses are 46 specific crimes grouped in 22 offense categories. Specific facts about these offenses are gathered and reported in the NIBRS system. In addition to the Group A offenses, eleven Group B offenses are reported with only the arrest information. The NIBRS system is in greater detail than the summary-based UCR system. As of 2004, 5,271 law enforcement agencies submitted NIBRS data. That amount represents 20% of the United States population and 16% of the crime statistics data collected by the FBI.
Try to answer this question if possible: Does the NIBRS system or UCR system have more detailed data?
Answer: NIBRS


Input: Read this: An in-depth study of MP3 audio quality, sound artist and composer Ryan Maguire's project "The Ghost in the MP3" isolates the sounds lost during MP3 compression. In 2015, he released the track "moDernisT" (an anagram of "Tom's Diner"), composed exclusively from the sounds deleted during MP3 compression of the song "Tom's Diner", the track originally used in the formulation of the MP3 standard. A detailed account of the techniques used to isolate the sounds deleted during MP3 compression, along with the conceptual motivation for the project, was published in the 2014 Proceedings of the International Computer Music Conference.
Question: What did the study aim to isolate?

Output:
sounds lost during MP3 compression
