In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Question: Question: How high is the gamma radiation from nuclear fuel? Passage:The nuclear fuel elements were made of refractory ceramic based on beryllium oxide, with enriched uranium dioxide as fuel and small amount of zirconium dioxide for structural stability. The fuel elements were hollow hexagonal tubes about long with distance between the outer parallel planes, with inside diameter of . They were manufactured by high-pressure extruding of the green compact, then sintering almost to its theoretical density. The core consisted of 465,000 individual elements stacked to form 27,000 airflow channels; the design with small unattached elements reduced problems related with thermal stresses. The elements were designed for average operation temperature of ; the autoignition temperature of the reactor base plates was only 150 °C higher. The neutron flux was calculated to be 9×10 neutrons/(cm·s) in the aft and 7×10 neutrons/(cm·s) in the nose. The gamma radiation level was fairly high due to the lack of shielding; radiation hardening for the guidance electronics had to be designed.
 Links: a. Beryllium oxide b. Radiation hardening c. Nuclear fuel d. Radiation hardening

Answer: c


Question: 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".
 Links: a. Republic of Ireland b. Seville Declarations on the Treaty of Nice c. Neutral country d. Seville Declarations on the Treaty of Nice

Answer: b


Question: Question: Who won the 1947 tournament that the IFA XI were runners up in? Passage:Between 1946 and 1950, Walsh made 11 appearances and scored seven goals for the IFA XI. These include two Victory internationals played in early 1946. On 2 February, at Windsor Park he made his debut for the IFA XI in a 3–2 defeat to Scotland, scoring both of his teams goals. Then, on 4 May, he helped the IFA XI defeat Wales 1–0 at Ninian Park. On 27 November 1946, he played for the IFA XI a 0–0 draw with Scotland. Together with Johnny Carey, Con Martin, Bill Gorman, Tommy Eglington, Alex Stevenson and Peter Farrell, he was one of seven players born in the Irish Free State to play for the IFA XI that day. The draw helped the team finish as runners-up in the 1947 British Home Championship. Walsh also helped the IFA XI gain some further respectable results, including a 2–0 win against Scotland on 4 October 1947 and a 2–2 draw with England at Goodison Park on 5 November 1947. It was at Goodison that Walsh scored his third goal for the IFA XI, in a game he was later to describe as the highlight of his footballing career.
 Links: a. Scotland national football team b. England national football team c. Bill Gorman d. 1946–47 British Home Championship
