Input: Read this: Despite the dominance of the above formula, there are documented attempts of the financial industry, occurring before the crisis, to address the formula limitations, specifically the lack of dependence dynamics and the poor representation of extreme events. The volume "Credit Correlation: Life After Copulas", published in 2007 by World Scientific, summarizes a 2006 conference held by Merrill Lynch in London where several practitioners attempted to propose models rectifying some of the copula limitations. See also the article by Donnelly and Embrechts and the book by Brigo, Pallavicini and Torresetti, that reports relevant warnings and research on CDOs appeared in 2006.
Question: What year did the book by Brigo, Pallavicini and Torresetti report warnings and research on CDOs?

Output: 2006

Input: Read this: Greek demonstrates several linguistic features that are shared with other Balkan languages, such as Albanian, Bulgarian and Eastern Romance languages (see Balkan sprachbund), and has absorbed many foreign words, primarily of Western European and Turkish origin. Because of the movements of Philhellenism and the Diafotismos in the 19th century, which emphasized the modern Greeks' ancient heritage, these foreign influences were excluded from official use via the creation of Katharevousa, a somewhat artificial form of Greek purged of all foreign influence and words, as the official language of the Greek state. In 1976, however, the Hellenic Parliament voted to make the spoken Dimotiki the official language, making Katharevousa obsolete.
Question: What other dialects share a thread with the French language?

Output: unanswerable

Input: Read this: A reference simulation software implementation, written in the C language and later known as ISO 11172-5, was developed (in 19911996) by the members of the ISO MPEG Audio committee in order to produce bit compliant MPEG Audio files (Layer 1, Layer 2, Layer 3). It was approved as a committee draft of ISO/IEC technical report in March 1994 and printed as document CD 11172-5 in April 1994. It was approved as a draft technical report (DTR/DIS) in November 1994, finalized in 1996 and published as international standard ISO/IEC TR 11172-5:1998 in 1998. The reference software in C language was later published as a freely available ISO standard. Working in non-real time on a number of operating systems, it was able to demonstrate the first real time hardware decoding (DSP based) of compressed audio. Some other real time implementation of MPEG Audio encoders were available for the purpose of digital broadcasting (radio DAB, television DVB) towards consumer receivers and set top boxes.
Question: Which language was the reference simulation software written in?

Output:
C
