Input: Uranium
In 1972, the French physicist Francis Perrin discovered fifteen ancient and no longer active natural nuclear fission reactors in three separate ore deposits at the Oklo mine in Gabon, West Africa, collectively known as the Oklo Fossil Reactors. The ore deposit is 1.7 billion years old; then, uranium-235 constituted about 3% of the total uranium on Earth. This is high enough to permit a sustained nuclear fission chain reaction to occur, provided other supporting conditions exist. The capacity of the surrounding sediment to contain the nuclear waste products has been cited by the U.S. federal government as supporting evidence for the feasibility to store spent nuclear fuel at the Yucca Mountain nuclear waste repository.

When the Oklo mine ore deposits came into being, what percentage of uranium on Earth consisted of uranium-235?
Output: 3%

Input: American Idol
The declining trend however continued into season eight, as total viewers numbers fell by 510% for early episodes compared to season seven, and by 9% for the finale. In season nine, Idol's six-year extended streak of perfection in the ratings was broken, when NBC's coverage of the 2010 Winter Olympics on February 17 beat Idol in the same time slot with 30.1 million viewers over Idol's 18.4 million. Nevertheless, American Idol overall finished its ninth season as the most watched TV series for the sixth year running, breaking the previous record of five consecutive seasons achieved by CBS' All in the Family and NBC's The Cosby Show.

Which television network originally aired All in the Family?
Output: CBS

Input: Eritrea
During the Middle Ages, the Eritrea region was known as Medri Bahri ("sea-land"). The name Eritrea is derived from the ancient Greek name for Red Sea ( Erythra Thalassa, based on the adjective erythros "red"). It was first formally adopted in 1890, with the formation of Italian Eritrea (Colonia Eritrea). The territory became the Eritrea Governorate within Italian East Africa in 1936. Eritrea was annexed by Ethiopia in 1953 (nominally within a federation until 1962) and an Eritrean Liberation Front formed in 1960. Eritrea gained independence following the 1993 referendum, and the name of the new state was defined as State of Eritrea in the 1997 constitution.[citation needed]

When did Eritrea gain independence?
Output: following the 1993 referendum

Input: Mexico City
A special case is that of El Colegio Nacional, created during the district's governmental period of Miguel Aleman Valdes to have, in Mexico, an institution similar to the College of France. The select and privileged group of Mexican scientists and artists belonging to this institutionmembership is for lifeinclude, among many, Mario Lavista, Ruy Perez Tamayo, Jose Emilio Pacheco, Marcos Moshinsky (d.2009), Guillermo Soberon Acevedo. Members are obligated to publicly disclose their works through conferences and public events such as concerts and recitals.

What is El Colegio Nacional modeled after?
Output:
College of France
