The MoD states that its principal objectives are to defend the United Kingdom of Great Britain and Northern Ireland and its interests and to strengthen international peace and stability. With the collapse of the Soviet Union and the end of the Cold War, the MoD does not foresee any short-term conventional military threat; rather, it has identified weapons of mass destruction, international terrorism, and failed and failing states as the overriding threats to Britain's interests. The MoD also manages day-to-day running of the armed forces, contingency planning and defence procurement.
The UK consists of what two areas?
Great Britain and Northern Ireland


Input: Saint Helena
During this period, the island enjoyed increased revenues through the sale of flax, with prices peaking in 1951. However, the industry declined because of transportation costs and competition from synthetic fibres. The decision by the British Post Office to use synthetic fibres for its mailbags was a further blow, contributing to the closure of the island's flax mills in 1965.

What did the Island sell for increased revenue during this period?
Output: flax


Input: Article: In his role as god of prophecy and truth, Apollo had the epithets Manticus (/ˈmæntᵻkəs/ MAN-ti-kəs; Μαντικός, Mantikos, literally "prophetic"), Leschenorius (/ˌlɛskᵻˈnɔəriəs/ LES-ki-NOHR-ee-əs; Λεσχηνόριος, Leskhēnorios, from λεσχήνωρ, "converser"), and Loxias (/ˈlɒksiəs/ LOK-see-əs; Λοξίας, Loxias, from λέγειν, "to say"). The epithet "Loxias" has historically been associated with λοξός, "ambiguous". In this respect, the Romans called him Coelispex (/ˈsɛlᵻspɛks/ SEL-i-speks; from Latin coelum, "sky", and specere, "to look at"). The epithet Iatromantis (/aɪˌætrəˈmæntɪs/ eye-AT-rə-MAN-tis; Ἰατρομάντις, Iātromantis, from ἰατρός, "physician", and μάντις, "prophet") refers to both his role as a god of healing and of prophecy. As god of music and arts, Apollo had the epithet Musagetes (/mjuːˈsædʒᵻtiːz/ mew-SAJ-i-teez; Doric Μουσαγέτας, Mousāgetās) or Musegetes (/mjuːˈsɛdʒᵻtiːz/ mew-SEJ-i-teez; Μουσηγέτης, Mousēgetēs, from Μούσα, "Muse", and ἡγέτης, "leader").

Input: Annelid
It is thought that annelids were originally animals with two separate sexes, which released ova and sperm into the water via their nephridia. The fertilized eggs develop into trochophore larvae, which live as plankton. Later they sink to the sea-floor and metamorphose into miniature adults: the part of the trochophore between the apical tuft and the prototroch becomes the prostomium (head); a small area round the trochophore's anus becomes the pygidium (tail-piece); a narrow band immediately in front of that becomes the growth zone that produces new segments; and the rest of the trochophore becomes the peristomium (the segment that contains the mouth).

What do annelid eggs become?
Output:
trochophore larvae
