Question: Do fewer than 1000 people inhabit the town where Howells was born in 1962? Passage:Howells was born in 1962 in his grandmother's house in Bapchild, Kent in the South of England. He was raised in nearby Sittingbourne, and attended Minterne County Junior School and Borden Grammar School. In the 1970s, he participated in youth theatre companies including Kent County Youth Theatre and Sittingbourne Youth Theatre. From 1981-84 he attended Bretton Hall College in West Yorkshire, graduating with a bachelor's degree in Drama and English. After working as a jobbing actor and director in provincial productions of plays and pantomimes, in 1990 Howells joined the Citizens Theatre Company in Glasgow, Scotland as an assistant director to Giles Havergal (one of the company's three pioneering directors, alongside Philip Prowse and the late Robert David MacDonald). While working at the Citizens Theatre, Howells met Stewart Laing, and Laing cast Howells alongside the drag performers Leigh Bowery and Ivan Cartwright in a production of Copi's scatological play The Homosexual or the Difficulty of Sexpressing Oneself (1971) -- Laing's first directorial production (co-directed with Gerrard McArthur). The play toured to Glasgow, London and Manchester in 1993-94. Howells recalled that Time Out described it as a hymn to tastelessness. I blacked up and was an Asian transsexual with a Carry on up the Khyber accent.’ Bowery was a profound influence on Howells and the two were close friends until Bowery's premature death in late 1994.

Question: What countries signed the treaty that acknowledges Ireland's "traditional policy of military neutrality"? Passage:Ireland has been neutral in international relations since the 1930s. The nature of Irish neutrality has varied over time, and has been contested since the 1970s. Historically, the state was a "non-belligerent" in the Second World War (see Irish neutrality during World War II) and has never joined NATO, although during the Cold War it was anti-communist and aloof from the Non-Aligned Movement. The compatibility of neutrality with Ireland's membership of the European Union has been a point of debate in EU treaty referendum campaigns since the 1990s. The Seville Declarations on the Treaty of Nice acknowledge Ireland's "traditional policy of military neutrality", reflecting the narrow formulation of successive Irish governments. Others define Irish neutrality more broadly, as having "a strong normative focus, with a commitment to development, United Nations peacekeeping, human rights and disarmament".
