Problem: Please answer a question about the following article about Mammal:
Molecular studies based on DNA analysis have suggested new relationships among mammal families over the last few years. Most of these findings have been independently validated by retrotransposon presence/absence data. Classification systems based on molecular studies reveal three major groups or lineages of placental mammals- Afrotheria, Xenarthra, and Boreoeutheria- which diverged from early common ancestors in the Cretaceous. The relationships between these three lineages is contentious, and all three possible different hypotheses have been proposed with respect to which group is basal with respect to other placentals. These hypotheses are Atlantogenata (basal Boreoeutheria), Epitheria (basal Xenarthra), and Exafroplacentalia (basal Afrotheria). Boreoeutheria in turn contains two major lineages- Euarchontoglires and Laurasiatheria.
Through Molecular studies, what was used to suggest new relationships among mammal families?
A: DNA analysis
Problem: Please answer a question about the following article about Philadelphia:
Irish, Italians, Polish, Germans, English, and Greeks are the largest ethnic European groups in the city. Philadelphia has the second-largest Irish and Italian populations in the United States, after New York City. South Philadelphia remains one of the largest Italian neighborhoods in the country and is home to the Italian Market. The Pennsport neighborhood and Gray's Ferry section of South Philadelphia, home to many Mummer clubs, are well known as Irish neighborhoods. The Kensington section, Port Richmond, and Fishtown have historically been heavily Irish and Polish. Port Richmond is well known in particular as the center of the Polish immigrant and Polish-American community in Philadelphia, and it remains a common destination for Polish immigrants. Northeast Philadelphia, although known for its Irish and Irish-American population, is also home to a large Jewish and Russian population. Mount Airy in Northwest Philadelphia also contains a large Jewish community, while nearby Chestnut Hill is historically known as an Anglo-Saxon Protestant stronghold.

Problem: Please answer a question about the following article about Russian Soviet Federative Socialist Republic:
On December 24, Yeltsin informed the Secretary-General of the United Nations that by agreement of the member states of the CIS Russian Federation would assume the membership of the Soviet Union in all UN organs (including permanent membership in the UN Security Council). Thus, Russia is considered to be an original member of the UN (since October 24, 1945) along with Ukraine (Ukrainian SSR) and Belarus (Byelorussian SSR). On December 25—just hours after Gorbachev resigned as president of the Soviet Union—the Russian SFSR was renamed the Russian Federation (Russia), reflecting that it was now a sovereign state with Yeltsin assuming the Presidency. The change was originally published on January 6, 1992 (Rossiyskaya Gazeta). According to law, during 1992, it was allowed to use the old name of the RSFSR for official business (forms, seals and stamps). The Russian Federation's Constitution (Fundamental Law) of 1978, though with the 1991–1992 Amendements, remained in effect until the 1993 Russian constitutional crisis.
What was the new name given to the Russian SFSR after the resignation of Gorbachev?
A: the Russian Federation
