Article: Evidence from the early technical literature concerning electrical recording suggests that it wasn't until the 1942–1949 period that there were serious efforts to standardize recording characteristics within an industry. Heretofore, electrical recording technology from company to company was considered a proprietary art all the way back to the 1925 Western Electric licensed method used by Columbia and Victor. For example, what Brunswick-Balke-Collender (Brunswick Corporation) did was different from the practices of Victor.

Question: How far back did records show the art of sound recordings?
Ans: 1925


Here is a question about this article: The Greek national basketball team has a decades-long tradition of excellence in the sport, being considered among the world's top basketball powers. As of 2012, it ranked 4th in the world and 2nd in Europe. They have won the European Championship twice in 1987 and 2005, and have reached the final four in two of the last four FIBA World Championships, taking the second place in the world in 2006 FIBA World Championship, after a spectacular 101–95 win against Team USA in the tournament's semifinal.

So... 4th


The problem: Answer a question about this article:
Other stories result from a natural rivalry between two or more characters. Outside of performance, these are referred to as feuds. A feud can exist between any number of participants and can last for a few days up to multiple decades. The feud between Ric Flair and Ricky Steamboat lasted from the late 1970s into the early 1990s and allegedly spanned over two thousand matches (although most of those matches were mere dark matches). The career-spanning history between characters Mike Awesome and Masato Tanaka is another example of a long-running feud, as is the case of Stone Cold Steve Austin vs. Mr. McMahon, one of the most lucrative feuds in the World Wrestling Federation (WWF) during 1998 and 1999.
How long might a feud last?
****
The answer: a few days up to multiple decades


Problem: Please answer a question about the following article about Mandolin:
Mandolin awareness in the United States blossomed in the 1880s, as the instrument became part of a fad that continued into the mid-1920s. According to Clarence L. Partee, the first mandolin made in the United States was made in 1883 or 1884 by Joseph Bohmann, who was an established maker of violins in Chicago. Partee characterized the early instrument as being larger than the European instruments he was used to, with a "peculiar shape" and "crude construction," and said that the quality improved, until American instruments were "superior" to imported instruments. At the time, Partee was using an imported French-made mandolin.
When was the first madolin made in the US?
A: 1883 or 1884


Question: Read this and answer the question

In 2015, fragments of a very early Quran, dating back to 1370 years ago, were discovered in the library of the University of Birmingham, England. According to the tests carried out by Oxford University Radiocarbon Accelerator Unit, "with a probability of more than 95%, the parchment was from between 568 and 645". The manuscript is written in Hijazi script, an early form of written Arabic. This is possibly the earliest extant exemplar of the Quran, but as the tests allow a range of possible dates, it cannot be said with certainty which of the existing versions is the oldest. Saudi scholar Saud al-Sarhan has expressed doubt over the age of the fragments as they contain dots and chapter separators that are believed to have originated later.

What feature of the Birmingham Quran fragments' text make some doubt that it is older than other known versions of the Quran?
Answer: dots and chapter separators


A broad operational definition is sometimes used to encompass the complexity of these diverse phenomena, where a gene is defined as a union of genomic sequences encoding a coherent set of potentially overlapping functional products. This definition categorizes genes by their functional products (proteins or RNA) rather than their specific DNA loci, with regulatory elements classified as gene-associated regions.
What does the typical definition of a gene categorize genes by?
their specific DNA loci
