Problem: Biodiversity:

Endemic species can be threatened with extinction through the process of genetic pollution, i.e. uncontrolled hybridization, introgression and genetic swamping. Genetic pollution leads to homogenization or replacement of local genomes as a result of either a numerical and/or fitness advantage of an introduced species. Hybridization and introgression are side-effects of introduction and invasion. These phenomena can be especially detrimental to rare species that come into contact with more abundant ones. The abundant species can interbreed with the rare species, swamping its gene pool. This problem is not always apparent from morphological (outward appearance) observations alone. Some degree of gene flow is normal adaptation, and not all gene and genotype constellations can be preserved. However, hybridization with or without introgression may, nevertheless, threaten a rare species' existence.

What are side-effects of introduction and pollution?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Beyoncé's first solo recording was a feature on Jay Z's "'03 Bonnie & Clyde" that was released in October 2002, peaking at number four on the U.S. Billboard Hot 100 chart. Her first solo album Dangerously in Love was released on June 24, 2003, after Michelle Williams and Kelly Rowland had released their solo efforts. The album sold 317,000 copies in its first week, debuted atop the Billboard 200, and has since sold 11 million copies worldwide. The album's lead single, "Crazy in Love", featuring Jay Z, became Beyoncé's first number-one single as a solo artist in the US. The single "Baby Boy" also reached number one, and singles, "Me, Myself and I" and "Naughty Girl", both reached the top-five. The album earned Beyoncé a then record-tying five awards at the 46th Annual Grammy Awards; Best Contemporary R&B Album, Best Female R&B Vocal Performance for "Dangerously in Love 2", Best R&B Song and Best Rap/Sung Collaboration for "Crazy in Love", and Best R&B Performance by a Duo or Group with Vocals for "The Closer I Get to You" with Luther Vandross.
Beyonce's first solo album in the U.S. with what artist in the lead single?
A: Jay Z


Context and question: The geographical regions in which Iranian languages were spoken were pushed back in several areas by newly neighbouring languages. Arabic spread into some parts of Western Iran (Khuzestan), and Turkic languages spread through much of Central Asia, displacing various Iranian languages such as Sogdian and Bactrian in parts of what is today Turkmenistan, Uzbekistan and Tajikistan. In Eastern Europe, mostly comprising the territory of modern-day Ukraine, southern European Russia, and parts of the Balkans, the core region of the native Scythians, Sarmatians, and Alans had been decisively been taken over as a result of absorption and assimilation (e.g. Slavicisation) by the various Proto-Slavic population of the region, by the 6th century AD. This resulted in the displacement and extinction of the once predominant Scythian languages of the region. Sogdian's close relative Yaghnobi barely survives in a small area of the Zarafshan valley east of Samarkand, and Saka as Ossetic in the Caucasus, which is the sole remnant of the once predominant Scythian languages in Eastern Europe proper and large parts of the North Caucasus. Various small Iranian languages in the Pamirs survive that are derived from Eastern Iranian.
What small area still speaks Sogdian?
Answer: unanswerable


Question: Italy is home to a vast array of native regional minority languages, most of which are Romance-based and have their own local variants. These regional languages are often referred to colloquially or in non-linguistic circles as Italian "dialects," or dialetti (standard Italian for "dialects"). However, the majority of the regional languages in Italy are in fact not actually "dialects" of standard Italian in the strict linguistic sense, as they are not derived from modern standard Italian but instead evolved locally from Vulgar Latin independent of standard Italian, with little to no influence from what is now known as "standard Italian." They are therefore better classified as individual languages rather than "dialects."
Is there an answer to this question: Which country is home to lots of native regional majority languages?

Answer: unanswerable


QUES: Though still predominantly green, post-2004 series incorporate other colors to better distinguish different denominations. As a result of a 2008 decision in an accessibility lawsuit filed by the American Council of the Blind, the Bureau of Engraving and Printing is planning to implement a raised tactile feature in the next redesign of each note, except the $1 and the version of the $100 bill already in process. It also plans larger, higher-contrast numerals, more color differences, and distribution of currency readers to assist the visually impaired during the transition period.

Who are transition periods meant to assist?
