There is no single definition of an "aircraft carrier", and modern navies use several variants of the type. These variants are sometimes categorized as sub-types of aircraft carriers, and sometimes as distinct types of naval aviation-capable ships. Aircraft carriers may be classified according to the type of aircraft they carry and their operational assignments. Admiral Sir Mark Stanhope, former head of the Royal Navy, has said that "To put it simply, countries that aspire to strategic international influence have aircraft carriers".
Who said, "countries that aspire to strategic local influence have aircraft carriers"?
A: unanswerable

Thermal conductivity gauges rely on the fact that the ability of a gas to conduct heat decreases with pressure. In this type of gauge, a wire filament is heated by running current through it. A thermocouple or Resistance Temperature Detector (RTD) can then be used to measure the temperature of the filament. This temperature is dependent on the rate at which the filament loses heat to the surrounding gas, and therefore on the thermal conductivity. A common variant is the Pirani gauge which uses a single platinum filament as both the heated element and RTD. These gauges are accurate from 10 torr to 103 torr, but they are sensitive to the chemical composition of the gases being measured.
A Pirani gauge is accurate within what ranges?
A: 10 torr to 103 torr

Since the start of the 199495 season, the FA Cup has been sponsored. However, to protect the identity of the competition, the sponsored name has always included 'The FA Cup' in addition to the sponsor's name, unlike sponsorship deals for the League Cup where the word 'cup' is preceded by only the sponsor's name. Sponsorship deals run for four years, though as in the case of E.ON one-year extensions may be agreed. Emirates airline is the sponsor from 2015 to 2018, renaming the competition as 'The Emirates FA Cup', unlike previous editions, which included 'The FA Cup in association with E.ON' and 'The FA Cup with Budweiser'.
What is the competition called now?
A:
The Emirates FA Cup
