Question: Astronomy: The first textual mention of astronomical concepts comes from the Vedas, religious literature of India. According to Sarma (2008): "One finds in the Rigveda intelligent speculations about the genesis of the universe from nonexistence, the configuration of the universe, the spherical self-supporting earth, and the year of 360 days divided into 12 equal parts of 30 days each with a periodical intercalary month.". The first 12 chapters of the Siddhanta Shiromani, written by Bhāskara in the 12th century, cover topics such as: mean longitudes of the planets; true longitudes of the planets; the three problems of diurnal rotation; syzygies; lunar eclipses; solar eclipses; latitudes of the planets; risings and settings; the moon's crescent; conjunctions of the planets with each other; conjunctions of the planets with the fixed stars; and the patas of the sun and moon. The 13 chapters of the second part cover the nature of the sphere, as well as significant astronomical and trigonometric calculations based on it.
Is there an answer to this question: Which text was the first to have concepts of astronomy in it?

Question: Arsenal's longest-running and deepest rivalry is with their nearest major neighbours, Tottenham Hotspur; matches between the two are referred to as North London derbies.

In addition, Arsenal and Manchester United developed a strong on-pitch rivalry in the late 1980s, which intensified in recent years when both clubs were competing for the Premier League title – so much so that a 2003 online poll by the Football Fans Census listed Manchester United as Arsenal's biggest rivals, followed by Tottenham and Chelsea. A 2008 poll listed the Tottenham rivalry as more important.
Is there an answer to this question: What football club is Arsenal's greatest rival?

Question: In exchange for Rupert Murdoch's support, Blair agreed not to join the European Exchange Rate Mechanism – which John Major had withdrawn the country from in September 1992 after barely two years. Cabinet Minister Peter Mandelson was "outed" by Matthew Parris (a former Sun columnist) on BBC TV's Newsnight in November 1998. Misjudging public response, The Sun's editor David Yelland demanded to know in a front page editorial whether Britain was governed by a "gay mafia" of a "closed world of men with a mutual self-interest". Three days later the paper apologised in another editorial which said The Sun would never again reveal a person's sexuality unless it could be defended on the grounds of "overwhelming public interest".
Is there an answer to this question: What did The Sun say its policy about revealing an individual's sexuality would be moving forward?

Answer:
The Sun would never again reveal a person's sexuality unless it could be defended on the grounds of "overwhelming public interest"
