Problem: Aircraft carrier:

In December 2009, then Indian Navy chief Admiral Nirmal Kumar Verma said at his maiden navy week press conference that concepts currently being examined by the Directorate of Naval Design for the second indigenous aircraft carrier (IAC-2), are for a conventionally powered carrier displacing over 50,000 tons and equipped with steam catapults (rather than the ski-jump on the Gorshkov/Vikramaditya and the IAC) to launch fourth-generation aircraft. Later on in August 2013 Vice Admiral RK Dhowan, while talking about the detailed study underway on the IAC-II project, said that nuclear propulsion was also being considered. The navy also evaluated the Electromagnetic Aircraft Launch System (EMALS), which is being used by the US Navy in their latest Gerald R. Ford-class aircraft carriers. General Atomics, the developer of the EMALS, was cleared by the US government to give a technical demonstration to Indian Navy officers, who were impressed by the new capabilities of the system. The EMALS enables launching varied aircraft including unmanned combat air vehicles (UCAV). The aim is to have a total of three aircraft carriers in service, with two fully operational carriers and the third in refit.

Problem: In April 2009, the United States Supreme Court agreed to hear a suit over reverse discrimination brought by 20 white and Hispanic firefighters against the city. The suit involved the 2003 promotion test for the New Haven Fire Department. After the tests were scored, no blacks scored high enough to qualify for consideration for promotion, so the city announced that no one would be promoted. On 29 June 2009, the United States Supreme Court ruled in favor of the firefighters, agreeing that they were improperly denied promotion because of their race. The case, Ricci v. DeStefano, became highly publicized and brought national attention to New Haven politics due to the involvement of then-Supreme Court nominee (and Yale Law School graduate) Sonia Sotomayor in a lower court decision.
Which Supreme Court Justice was a graduate of Yale Law School and was currently undergoing the nomination process at the time of the 2009 lawsuit filed by firefighters against the city of New Haven?

Answer: Sonia Sotomayor

In the past, people at Eton have occasionally been guilty of antisemitism. For a time, new admissions were called 'Jews' by their fellow Collegers. In 1945, the school introduced a nationality statute conditioning entry on the applicant's father being British by birth. The statute was removed after the intervention of Prime Minister Harold Macmillan in the 1960s after it came to the attention of Oxford's Wykeham Professor of Logic, A. J. Ayer, himself Jewish and an Old Etonian, who "suspected a whiff of anti-semitism".
