Input: Question: How many nations belong to the organization that Ireland has never joined? Passage 1: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".
 Passage 2:Granger realises that she will need to ask for small portions at the first meal to preserve her appetite, despite asking she is presented with turkey slices and sixteen types of vegetables. She finishes this and is presented with a whole Christmas pudding to eat which she initially thinks is for the three to share. Now starting to feel full up she goes to the second where David is using recipes from a Delia Smith book. He presents her with a large plate of pasta, then a whole fish and finally the turkey. After initially declining David's offer of more Brussels sprouts she reluctantly accepts as it's a competition between him and Hugo as to who eats more sprouts, David or the guest (representing Hugo), she gives Hugo his first win against his father in any competition. Now completely full up she crawls to Alice's house and in vain tries to get Alice and her family to offer her just a cup of tea by telling a fictionalised version of the events she's been through. Mrs Tinker serves her balls of stuffing as a starter and then a main course. After the third meal the vicar gets a cab home (which is just opposite Alice's). Newitt then arrives offering her the fourth lunch and she reluctantly goes with him where he serves a large selection of food including tripe, all of which is offered to her as Newitt has a stomach upset. The vicar is finally given a lift home in the bucket of his tractor.
