QUES: If a tuberculosis infection does become active, it most commonly involves the lungs (in about 90% of cases). Symptoms may include chest pain and a prolonged cough producing sputum. About 25% of people may not have any symptoms (i.e. they remain "asymptomatic"). Occasionally, people may cough up blood in small amounts, and in very rare cases, the infection may erode into the pulmonary artery or a Rasmussen's aneurysm, resulting in massive bleeding. Tuberculosis may become a chronic illness and cause extensive scarring in the upper lobes of the lungs. The upper lung lobes are more frequently affected by tuberculosis than the lower ones. The reason for this difference is not clear. It may be due either to better air flow, or to poor lymph drainage within the upper lungs.
What percentage of cases erode into the pulmonary artery?

QUES: The Red Rose of Lancaster is the county flower found on the county's heraldic badge and flag. The rose was a symbol of the House of Lancaster, immortalised in the verse "In the battle for England's head/York was white, Lancaster red" (referring to the 15th-century Wars of the Roses). The traditional Lancashire flag, a red rose on a white field, was not officially registered. When an attempt was made to register it with the Flag Institute it was found that it was officially registered by Montrose in Scotland, several hundred years earlier with the Lyon Office. Lancashire's official flag is registered as a red rose on a gold field.

QUES: Airports may also contain premium and VIP services. The premium and VIP services may include express check-in and dedicated check-in counters. These services are usually reserved for First and Business class passengers, premium frequent flyers, and members of the airline's clubs. Premium services may sometimes be open to passengers who are members of a different airline's frequent flyer program. This can sometimes be part of a reciprocal deal, as when multiple airlines are part of the same alliance, or as a ploy to attract premium customers away from rival airlines.
