QUES: Genetic studies of mitochondrial DNA (mtDNA) of Amerindians and some Siberian and Central Asian peoples also revealed that the gene pool of the Turkic-speaking peoples of Siberia such as Altaians, Khakas, Shors and Soyots, living between the Altai and Lake Baikal along the Sayan mountains, are genetically closest to Amerindians.[citation needed] This view is shared by other researchers who argue that "the ancestors of the American Indians were the first to separate from the great Asian population in the Middle Paleolithic. 2012 research found evidence for a recent common ancestry between Native Americans and indigenous Altaians based on mitochondrial DNA and Y-Chromosome analysis. The paternal lineages of Altaians mostly belong to the subclades of haplogroup P-M45 (xR1a 38-93%; xQ1a 4-32%).

What group were the ancestors of the American Indians separated from?
What is the answer?
ANS: Asian population
QUES: The first Roman republican wars were wars of both expansion and defence, aimed at protecting Rome itself from neighbouring cities and nations and establishing its territory in the region. Initially, Rome's immediate neighbours were either Latin towns and villages, or else tribal Sabines from the Apennine hills beyond. One by one Rome defeated both the persistent Sabines and the local cities, both those under Etruscan control and those that had cast off their Etruscan rulers. Rome defeated Latin cities in the Battle of Lake Regillus in 496 BC, the Battle of Mons Algidus in 458 BC, the Battle of Corbione in 446 BC, the Battle of Aricia, and especially the Battle of the Cremera in 477 BC wherein it fought against the most important Etruscan city of Veii.

In what year did Rome claim victory against the city of Veii?
What is the answer?
ANS: 477 BC
QUES: While Japan had a large number of submarines, they did not make a significant impact on the war. In 1942, the Japanese fleet subs performed well, knocking out or damaging many Allied warships. However, Imperial Japanese Navy (and pre-war U.S.) doctrine stipulated that only fleet battles, not guerre de course (commerce raiding) could win naval campaigns. So, while the US had an unusually long supply line between its west coast and frontline areas, leaving it vulnerable to submarine attack, Japan used its submarines primarily for long-range reconnaissance and only occasionally attacked U.S. supply lines. The Japanese submarine offensive against Australia in 1942 and 1943 also achieved little.

When was the Japanese submarine offensive against Australia?
What is the answer?
ANS:
1942 and 1943
