Problem: Please answer a question about the following article about Ashkenazi Jews:
Efforts to identify the origins of Ashkenazi Jews through DNA analysis began in the 1990s. Currently, there are three types of genetic origin testing, autosomal DNA (atDNA), mitochondrial DNA (mtDNA), and Y-chromosomal DNA (Y-DNA). Autosomal DNA is a mixture from an individual's entire ancestry, Y-DNA shows a male's lineage only along his strict-paternal line, mtDNA shows any person's lineage only along the strict-maternal line. Genome-wide association studies have also been employed to yield findings relevant to genetic origins.
When did efforts begin to try and identify the origins of Ashkenazi Jews through DNA analysis?
A: the 1990s
Problem: Please answer a question about the following article about Hunter-gatherer:
In the 1950s, Lewis Binford suggested that early humans were obtaining meat via scavenging, not hunting. Early humans in the Lower Paleolithic lived in forests and woodlands, which allowed them to collect seafood, eggs, nuts, and fruits besides scavenging. Rather than killing large animals for meat, according to this view, they used carcasses of such animals that had either been killed by predators or that had died of natural causes. Archaeological and genetic data suggest that the source populations of Paleolithic hunter-gatherers survived in sparsely wooded areas and dispersed through areas of high primary productivity while avoiding dense forest cover.
What type of area did early humans avoid?
A: dense forest
Problem: Please answer a question about the following article about Montevideo:
In the early 20th century, many Europeans (particularly Spaniards and Italians but also thousands from Central Europe) immigrated to the city. In 1908, 30% of the city's population of 300,000 was foreign-born. In that decade the city expanded quickly: new neighbourhoods were created and many separate settlements were annexed to the city, among which were the Villa del Cerro, Pocitos, the Prado and Villa Colon. The Rodo Park and the Estadio Gran Parque Central were also established, which served as poles of urban development.
What century did many Europeans immigrate to the city of Montevideo?
A: early 20th century
