Problem: General Electric:

GE has a history of some of its activities giving rise to large-scale air and water pollution. Based on year 2000 data, researchers at the Political Economy Research Institute listed the corporation as the fourth-largest corporate producer of air pollution in the United States, with more than 4.4 million pounds per year (2,000 tons) of toxic chemicals released into the air. GE has also been implicated in the creation of toxic waste. According to EPA documents, only the United States Government, Honeywell, and Chevron Corporation are responsible for producing more Superfund toxic waste sites.

Problem: Hindu philosophy:

Ramanuja (c. 1037–1137) was the foremost proponent of the philosophy of Viśiṣṭādvaita or qualified non-dualism. Viśiṣṭādvaita advocated the concept of a Supreme Being with essential qualities or attributes. Viśiṣṭādvaitins argued against the Advaitin conception of Brahman as an impersonal empty oneness. They saw Brahman as an eternal oneness, but also as the source of all creation, which was omnipresent and actively involved in existence. To them the sense of subject-object perception was illusory and a sign of ignorance. However, the individual's sense of self was not a complete illusion since it was derived from the universal beingness that is Brahman. Ramanuja saw Vishnu as a personification of Brahman.

Problem: Eritrea:

In the vacuum that followed the 1889 death of Emperor Yohannes II, Gen. Oreste Baratieri occupied the highlands along the Eritrean coast and Italy proclaimed the establishment of the new colony of Italian Eritrea, a colony of the Kingdom of Italy. In the Treaty of Wuchale (It. Uccialli) signed the same year, King Menelik of Shewa, a southern Ethiopian kingdom, recognized the Italian occupation of his rivals' lands of Bogos, Hamasien, Akkele Guzay, and Serae in exchange for guarantees of financial assistance and continuing access to European arms and ammunition. His subsequent victory over his rival kings and enthronement as Emperor Menelek II (r. 1889–1913) made the treaty formally binding upon the entire territory.

In what modern-day country is Wuchale?

A: unanswerable


Problem: Russian language:

The language was first introduced in North America when Russian explorers voyaged into Alaska and claimed it for Russia during the 1700s. Although most colonists left after the United States bought the land in 1867, a handful stayed and preserved the Russian language in this region to this day, although only a few elderly speakers of this unique dialect are left. Sizable Russian-speaking communities also exist in North America, especially in large urban centers of the U.S. and Canada, such as New York City, Philadelphia, Boston, Los Angeles, Nashville, San Francisco, Seattle, Spokane, Toronto, Baltimore, Miami, Chicago, Denver and Cleveland. In a number of locations they issue their own newspapers, and live in ethnic enclaves (especially the generation of immigrants who started arriving in the early 1960s). Only about 25% of them are ethnic Russians, however. Before the dissolution of the Soviet Union, the overwhelming majority of Russophones in Brighton Beach, Brooklyn in New York City were Russian-speaking Jews. Afterward, the influx from the countries of the former Soviet Union changed the statistics somewhat, with ethnic Russians and Ukrainians immigrating along with some more Russian Jews and Central Asians. According to the United States Census, in 2007 Russian was the primary language spoken in the homes of over 850,000 individuals living in the United States.

What portion of Russian-speaking Americans are ethnic Russians?

A:
about 25%
