Problem: Ashkenazi Jews:

In 2013, however, a study of Ashkenazi mitochondrial DNA by a team led by Martin B. Richards of the University of Huddersfield in England reached different conclusions, again corroborating the pre-2006 origin hypothesis. Testing was performed on the full 16,600 DNA units composing mitochondrial DNA (the 2006 Behar study had only tested 1,000 units) in all their subjects, and the study found that the four main female Ashkenazi founders had descent lines that were established in Europe 10,000 to 20,000 years in the past while most of the remaining minor founders also have a deep European ancestry. The study states that the great majority of Ashkenazi maternal lineages were not brought from the Near East (i.e., they were non-Israelite), nor were they recruited in the Caucasus (i.e., they were non-Khazar), but instead they were assimilated within Europe, primarily of Italian and Old French origins. Richards summarized the findings on the female line as such: "[N]one [of the mtDNA] came from the North Caucasus, located along the border between Europe and Asia between the Black and Caspian seas. All of our presently available studies including my own, should thoroughly debunk one of the most questionable, but still tenacious, hypotheses: that most Ashkenazi Jews can trace their roots to the mysterious Khazar Kingdom that flourished during the ninth century in the region between the Byzantine Empire and the Persian Empire." The 2013 study estimated that 80 percent of Ashkenazi maternal ancestry comes from women indigenous to Europe, and only 8 percent from the Near East, while the origin of the remainder is undetermined. According to the study these findings "point to a significant role for the conversion of women in the formation of Ashkenazi communities."

A 2013 study estimates that what percentage of Ashkenazi maternal ancestry comes from women of undetermined origins?

Problem: Miami's heavy-rail rapid transit system, Metrorail, is an elevated system comprising two lines and 23 stations on a 24.4-mile (39.3 km)-long line. Metrorail connects the urban western suburbs of Hialeah, Medley, and inner-city Miami with suburban The Roads, Coconut Grove, Coral Gables, South Miami and urban Kendall via the central business districts of Miami International Airport, the Civic Center, and Downtown. A free, elevated people mover, Metromover, operates 21 stations on three different lines in greater Downtown Miami, with a station at roughly every two blocks of Downtown and Brickell. Several expansion projects are being funded by a transit development sales tax surcharge throughout Miami-Dade County.
How much doesn't it cost to use Metromover?

The European, American, and Japanese comics traditions have followed different paths. Europeans have seen their tradition as beginning with the Swiss Rodolphe Topffer from as early as 1827 and Americans have seen the origin of theirs in Richard F. Outcault's 1890s newspaper strip The Yellow Kid, though many Americans have come to recognize Topffer's precedence. Japan had a long prehistory of satirical cartoons and comics leading up to the World War II era. The ukiyo-e artist Hokusai popularized the Japanese term for comics and cartooning, manga, in the early 19th century. In the post-war era modern Japanese comics began to flourish when Osamu Tezuka produced a prolific body of work. Towards the close of the 20th century, these three traditions converged in a trend towards book-length comics: the comics album in Europe, the tankobon[a] in Japan, and the graphic novel in the English-speaking countries.
Who is considered to be the first comic creator in America?
A: Richard F. Outcault

Context and question: The climate of Antarctica does not allow extensive vegetation to form. A combination of freezing temperatures, poor soil quality, lack of moisture, and lack of sunlight inhibit plant growth. As a result, the diversity of plant life is very low and limited in distribution. The flora of the continent largely consists of bryophytes. There are about 100 species of mosses and 25 species of liverworts, but only three species of flowering plants, all of which are found in the Antarctic Peninsula: Deschampsia antarctica (Antarctic hair grass), Colobanthus quitensis (Antarctic pearlwort) and the non-native Poa annua (annual bluegrass). Growth is restricted to a few weeks in the summer.
What is diverse and widely distributed?
Answer: unanswerable

Question: In 2007, the official Xinhua News Agency reported that the resolution of the BeiDou system was as high as 0.5 metres. With the existing user terminals it appears that the calibrated accuracy is 20m (100m, uncalibrated).
Is there an answer to this question: Who reported the resolution of the BeiDou system in 2007?

Answer: the official Xinhua News Agency

QUES: A number of the city's downtown employers are relatively new, as there has been a marked trend of companies moving from satellite suburbs around Metropolitan Detroit into the downtown core.[citation needed] Compuware completed its world headquarters in downtown in 2003. OnStar, Blue Cross Blue Shield, and HP Enterprise Services are located at the Renaissance Center. PricewaterhouseCoopers Plaza offices are adjacent to Ford Field, and Ernst & Young completed its office building at One Kennedy Square in 2006. Perhaps most prominently, in 2010, Quicken Loans, one of the largest mortgage lenders, relocated its world headquarters and 4,000 employees to downtown Detroit, consolidating its suburban offices. In July 2012, the U.S. Patent and Trademark Office opened its Elijah J. McCoy Satellite Office in the Rivertown/Warehouse District as its first location outside Washington, D.C.'s metropolitan area.

What is the name Of the U.S. Patent office in Detroit?
What is the answer?

Elijah J. McCoy Satellite Office
