Input: Read this: Unveiled in 1888, Royal Arsenal's first crest featured three cannon viewed from above, pointing northwards, similar to the coat of arms of the Metropolitan Borough of Woolwich (nowadays transferred to the coat of arms of the Royal Borough of Greenwich). These can sometimes be mistaken for chimneys, but the presence of a carved lion's head and a cascabel on each are clear indicators that they are cannon. This was dropped after the move to Highbury in 1913, only to be reinstated in 1922, when the club adopted a crest featuring a single cannon, pointing eastwards, with the club's nickname, The Gunners, inscribed alongside it; this crest only lasted until 1925, when the cannon was reversed to point westward and its barrel slimmed down.
Question: What has been the Arsenal crest since 1925?

Input: Read this: Although many species can reproduce asexually and use similar mechanisms to regenerate after severe injuries, sexual reproduction is the normal method in species whose reproduction has been studied. The minority of living polychaetes whose reproduction and lifecycles are known produce trochophore larvae, that live as plankton and then sink and metamorphose into miniature adults. Oligochaetes are full hermaphrodites and produce a ring-like cocoon around their bodies, in which the eggs and hatchlings are nourished until they are ready to emerge.
Question: What can asexual reproduction techniques prevent annelids from doing?

Input: Read this: When paying a state visit to Britain, foreign heads of state are usually entertained by the Queen at Buckingham Palace. They are allocated a large suite of rooms known as the Belgian Suite, situated at the foot of the Minister's Staircase, on the ground floor of the north-facing Garden Wing. The rooms of the suite are linked by narrow corridors, one of them is given extra height and perspective by saucer domes designed by Nash in the style of Soane. A second corridor in the suite has Gothic influenced cross over vaulting. The Belgian Rooms themselves were decorated in their present style and named after Prince Albert's uncle Leopold I, first King of the Belgians. In 1936, the suite briefly became the private apartments of the palace when they were occupied by King Edward VIII.
Question: Which floor is the Belgian Suite restricted?

Input: Read this: Carthage was Palermo's major trading partner under the Phoenicians and the city enjoyed a prolonged peace during this period. Palermo came into contact with the Ancient Greeks between the 6th and the 5th centuries BC which preceded the Sicilian Wars, a conflict fought between the Greeks of Syracuse and the Phoenicians of Carthage for control over the island of Sicily. During this war the Greeks named the settlement Panormos () from which the current name is derived, meaning "all port" due to the shape of its coast. It was from Palermo that Hamilcar I's fleet (which was defeated at the Battle of Himera) was launched. In 409 B.C. the city was looted by Hermocrates of Syracuse. The Sicilian Wars ended in 265 BC when Carthage and Syracuse stopped warring and united in order to stop the Romans from gaining full control of the island during the First Punic War. In 276 BC, during the Pyrrhic War, Panormos briefly became a Greek colony after being conquered by Pyrrhus of Epirus, but returned to Phoenician Carthage in 275. In 254 BC Panormos was besieged and conquered by the Romans in the first battle of Panormus (the name Latin name). Carthage attempted to reconquer Panormus in 251 BC but failed.
Question: Who's fleet was launched from Carthage in 408 BC?
