Question: Passage: The term alloy is used to describe a mixture of atoms in which the primary constituent is a metal. The primary metal is called the base, the matrix, or the solvent. The secondary constituents are often called solutes. If there is a mixture of only two types of atoms, not counting impurities, such as a copper-nickel alloy, then it is called a binary alloy. If there are three types of atoms forming the mixture, such as iron, nickel and chromium, then it is called a ternary alloy. An alloy with four constituents is a quaternary alloy, while a five-part alloy is termed a quinary alloy. Because the percentage of each constituent can be varied, with any mixture the entire range of possible variations is called a system. In this respect, all of the various forms of an alloy containing only two constituents, like iron and carbon, is called a binary system, while all of the alloy combinations possible with a ternary alloy, such as alloys of iron, carbon and chromium, is called a ternary system. Question: A five-part alloy is known as?

Answer: ternary alloy


Question: Passage: Since the early 1950s on conventional carriers it has been the practice to recover aircraft at an angle to port of the axial line of the ship. The primary function of this angled deck is to allow aircraft that miss the arresting wires, referred to as a bolter, to become airborne again without the risk of hitting aircraft parked forward. The angled deck allows the installation of one or two "waist" catapults in addition to the two bow cats. An angled deck also improves launch and recovery cycle flexibility with the option of simultaneous launching and recovery of aircraft. Question: How many "waist" catapults can be installed with an angled deck?

Answer: one or two


Question: Passage: Southampton's largest retail centre, and 35th largest in the UK, is the WestQuay Shopping Centre, which opened in September 2000 and hosts major high street stores including John Lewis and Marks and Spencer. The centre was Phase Two of the West Quay development of the former Pirelli undersea cables factory; the first phase of this was the West Quay Retail Park, while the third phase (Watermark Westquay) was put on hold due to the recession. Work is has resumed in 2015, with plans for this third stage including shops, housing, an hotel and a public piazza alongside the Town Walls on Western Esplanade. Southampton has also been granted a licence for a large casino. A further part of the redevelopment of the West Quay site resulted in a new store, opened on 12 February 2009, for Swedish home products retailer IKEA. Marlands is a smaller shopping centre, built in the 1990s and located close to the northern side of WestQuay. Southampton currently has two disused shopping centres: the 1970s Eaststreet mall, and the 1980s Bargate centre. Neither of these were ever commercially successful; the former has been earmarked for redevelopment as a Morrison's supermarket, while the future of the latter is uncertain. There is also the East Street area which has been designated for speciality shopping, with the aim of promoting smaller retailers, alongside the chain store Debenhams. In 2007, Southampton was ranked 13th for shopping in the UK. Question: What was the name of the third phase of West Quay development that got put on hold because of the recession?

Answer:
Watermark Westquay
