Problem: Dell:

In 1986, Michael Dell brought in Lee Walker, a 51-year-old venture capitalist, as president and chief operating officer, to serve as Michael's mentor and implement Michael's ideas for growing the company. Walker was also instrumental in recruiting members to the board of directors when the company went public in 1988. Walker retired in 1990 due to health, and Michael Dell hired Morton Meyerson, former CEO and president of Electronic Data Systems to transform the company from a fast-growing medium-sized firm into a billion-dollar enterprise.

Problem: Slavs:

The first half of the 20th century in Russia and the Soviet Union was marked by a succession of wars, famines and other disasters, each accompanied by large-scale population losses. Stephen J.

When did Stephen J. Lee make his estimate about the Russian population?

A: unanswerable


Problem: Slavs:

On the other hand, I2a1b1 (P41.2) is typical of the South Slavic populations, being highest in Bosnia-Herzegovina (>50%). Haplogroup I2a2 is also commonly found in north-eastern Italians. There is also a high concentration of I2a2a in the Moldavian region of Romania, Moldova and western Ukraine. According to original studies, Hg I2a2 was believed to have arisen in the west Balkans sometime after the LGM, subsequently spreading from the Balkans through Central Russian Plain. Recently, Ken Nordtvedt has split I2a2 into two clades – N (northern) and S (southern), in relation where they arose compared to Danube river. He proposes that N is slightly older than S. He recalculated the age of I2a2 to be ~ 2550 years and proposed that the current distribution is explained by a Slavic expansion from the area north-east of the Carpathians.

I2a1b1 is typical of what populations?
---
A: South Slavic populations


Problem: Kievan Rus%27:

Kievan Rus' also played an important genealogical role in European politics. Yaroslav the Wise, whose stepmother belonged to the Macedonian dynasty, the greatest one to rule Byzantium, married the only legitimate daughter of the king who Christianized Sweden. His daughters became queens of Hungary, France and Norway, his sons married the daughters of a Polish king and a Byzantine emperor (not to mention a niece of the Pope), while his granddaughters were a German Empress and (according to one theory) the queen of Scotland. A grandson married the only daughter of the last Anglo-Saxon king of England. Thus the Rurikids were a well-connected royal family of the time.

Who did Yaroslav's sons marry?
---
A:
daughters of a Polish king and a Byzantine emperor
