Input: Read this: An alloy is a mixture of either pure or fairly pure chemical elements, which forms an impure substance (admixture) that retains the characteristics of a metal. An alloy is distinct from an impure metal, such as wrought iron, in that, with an alloy, the added impurities are usually desirable and will typically have some useful benefit. Alloys are made by mixing two or more elements; at least one of which being a metal. This is usually called the primary metal or the base metal, and the name of this metal may also be the name of the alloy. The other constituents may or may not be metals but, when mixed with the molten base, they will be soluble, dissolving into the mixture.
Question: What desirable characteristic doesn't alloy and an impure metal have?

QUES: A new approach to avoiding overhead wires is taken by the "second generation" tram/streetcar system in Bordeaux, France (entry into service of the first line in December 2003; original system discontinued in 1958) with its APS (alimentation par sol – ground current feed). This involves a third rail which is flush with the surface like the tops of the running rails. The circuit is divided into segments with each segment energized in turn by sensors from the car as it passes over it, the remainder of the third rail remaining "dead". Since each energized segment is completely covered by the lengthy articulated cars, and goes dead before being "uncovered" by the passage of the vehicle, there is no danger to pedestrians. This system has also been adopted in some sections of the new tram systems in Reims, France (opened 2011) and Angers, France (also opened 2011). Proposals are in place for a number of other new services including Dubai, UAE; Barcelona, Spain; Florence, Italy; Marseille, France; Gold Coast, Australia; Washington, D.C., U.S.A.; Brasília, Brazil and Tours, France.

The dock connector also allowed the iPod to connect to accessories, which often supplement the iPod's music, video, and photo playback. Apple sells a few accessories, such as the now-discontinued iPod Hi-Fi, but most are manufactured by third parties such as Belkin and Griffin. Some peripherals use their own interface, while others use the iPod's own screen. Because the dock connector is a proprietary interface, the implementation of the interface requires paying royalties to Apple.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What are two companies that make iPod accessories?
Ah, so.. Belkin and Griffin


Question: Greece has universal health care. In a 2000 World Health Organization report, its health care system ranked 14th in overall performance of 191 countries surveyed. In a 2013 Save the Children report, Greece was ranked the 19th best country (out of 176 countries surveyed) for the state of mothers and newborn babies. In 2010, there were 138 hospitals with 31,000 beds in the country, but on 1 July 2011, the Ministry for Health and Social Solidarity announced its plans to decrease the number to 77 hospitals with 36,035 beds, as a necessary reform to reduce expenses and further enhance healthcare standards.[disputed – discuss] Greece's healthcare expenditures as a percentage of GDP were 9.6% in 2007 according to a 2011 OECD report, just above the OECD average of 9.5%. The country has the largest number of doctors-to-population ratio of any OECD country.
Try to answer this question if possible: What kind of health care exists in Greece?

Input: Read this: On 1 July 1967, BBC Two became the first television channel in Europe to broadcast regularly in colour, using the West German PAL system that is still in use today although being gradually superseded by digital systems. (BBC One and ITV began 625-line colour broadcasts simultaneously on 15 November 1969). Unlike other terrestrial channels, BBC Two does not have soap opera or standard news programming, but a range of programmes intended to be eclectic and diverse (although if a programme has high audience ratings it is often eventually repositioned to BBC One). The different remit of BBC2 allowed its first controller, Sir David Attenborough to commission the first heavyweight documentaries and documentary series such as Civilisation, The Ascent of Man and Horizon.
Question: What did BBC One and ITV begin on 15 November 1967?
