Input: Read this: Burke's Reflections sparked a pamphlet war. Thomas Paine penned the Rights of Man in 1791 as a response to Burke; Mary Wollstonecraft published A Vindication of the Rights of Men and James Mackintosh wrote Vindiciae Gallicae. Mackintosh was the first to see the Reflections as "the manifesto of a Counter Revolution". Mackintosh later agreed with Burke's views, remarking in December 1796 after meeting him, that Burke was "minutely and accurately informed, to a wonderful exactness, with respect to every fact relating to the French Revolution". Mackintosh later said: "Burke was one of the first thinkers as well as one of the greatest orators of his time. He is without parallel in any age, excepting perhaps Lord Bacon and Cicero; and his works contain an ampler store of political and moral wisdom than can be found in any other writer whatever".

Input: Read this: The USAF is the only branch of the U.S. military where NCO status is achieved when an enlisted person reaches the pay grade of E-5. In all other branches, NCO status is generally achieved at the pay grade of E-4 (e.g., a Corporal in the Army and Marine Corps, Petty Officer Third Class in the Navy and Coast Guard). The Air Force mirrored the Army from 1976 to 1991 with an E-4 being either a Senior Airman wearing three stripes without a star or a Sergeant (referred to as "Buck Sergeant"), which was noted by the presence of the central star and considered an NCO. Despite not being an NCO, a Senior Airman who has completed Airman Leadership School can be a supervisor according to the AFI 36-2618.
Question: When does NCO status happen in all other branches of the US Military?

Output: pay grade of E-4

Input: Read this: In May 2013, the club launched a new crest to improve the reproducibility of the design in print and broadcast media, particularly on a small scale. Critics[who?] suggested that it was external pressure from sports manufacturers Nike, Inc. that evoked the redesign as the number of colours has been reduced and the radial effect have been removed, making the kit more cost efficient to reproduce.[citation needed] The redesign was poorly received by supporters, with a poll on an Everton fan site registering a 91% negative response to the crest. A protest petition reached over 22,000 signatures before the club offered an apology and announced a new crest would be created for the 201415 season with an emphasis on fan consultation. Shortly afterwards, the Head of Marketing left the club.
Question: What executive issued the apology for Everton?
