Example Input: In the Solar System, a planet is said to be inferior or interior with respect to another planet if its orbit lies inside the other planet's orbit around the Sun. In this situation, the latter planet is said to be superior to the former. In the reference frame of the Earth, in which the terms were originally used, the inferior planets are Mercury and Venus, while the superior planets are Mars, Jupiter, Saturn, Uranus and Neptune. Dwarf planets like Ceres or Pluto and most asteroids are' superior' in the sense that they almost all orbit outside the orbit of Earth.
Example Output: what's the difference between inferior and superior planets

Example Input: Consequences of the Black Death included a series of religious, social, and economic upheavals, which had profound effects on the course of European history. The Black Death was one of the most devastating pandemics in human history, peaking in Europe between 1347 and 1350 with 30% to 65% of the population killed. It reduced world population from an estimated 450 million to between 350 and 375 million. It took 80 and in some areas more than 150 years for Europe's population to recover.
Example Output: the impact of the black death on medieval society

Example Input: The Nigerian Civil War, commonly known as the Biafran War (6 July 1967 -- 15 January 1970), was a war fought between the government of Nigeria and the secessionist state of Biafra. Biafra represented nationalist aspirations of the Igbo people, whose leadership felt they could no longer coexist with the Northern-dominated federal government. The conflict resulted from political, economic, ethnic, cultural and religious tensions which preceded Britain's formal decolonisation of Nigeria from 1960 to 1963. Immediate causes of the war in 1966 included a military coup, a counter-coup and persecution of Igbo living in Northern Nigeria. Control over oil production in the Niger Delta played a vital strategic role.
Example Output:
