Question: Although asthma is a chronic obstructive condition, it is not considered as a part of chronic obstructive pulmonary disease as this term refers specifically to combinations of disease that are irreversible such as bronchiectasis, chronic bronchitis, and emphysema. Unlike these diseases, the airway obstruction in asthma is usually reversible; however, if left untreated, the chronic inflammation from asthma can lead the lungs to become irreversibly obstructed due to airway remodeling. In contrast to emphysema, asthma affects the bronchi, not the alveoli.
Is there an answer to this question: What kind of condition is asthma?

Answer: a chronic obstructive condition


Question: The City Council (Gemeinderat) constitutes the executive government of the City of Bern and operates as a collegiate authority. It is composed of five councilors (German: Gemeinderat/-rätin), each presiding over a directorate (Direktion) comprising several departments and bureaus. The president of the executive department acts as mayor (Stadtpräsident). In the mandate period 2013–2016 (Legislatur) the City Council is presided by Stadtpräsident Alexander Tschäppät. Departmental tasks, coordination measures and implementation of laws decreed by the City Parliament are carried by the City Council. The regular election of the City Council by any inhabitant valid to vote is held every four years. Any resident of Bern allowed to vote can be elected as a member of the City Council. The delegates are selected by means of a system of Majorz. The mayor is elected as such as well by public election while the heads of the other directorates are assigned by the collegiate. The executive body holds its meetings in the Erlacherhof, built by architect Albrecht Stürler after 1747.
Is there an answer to this question: How does the government of Bern operate?

Question: The administration of London is formed of two tiers—a city-wide, strategic tier and a local tier. City-wide administration is coordinated by the Greater London Authority (GLA), while local administration is carried out by 33 smaller authorities. The GLA consists of two elected components; the Mayor of London, who has executive powers, and the London Assembly, which scrutinises the mayor's decisions and can accept or reject the mayor's budget proposals each year. The headquarters of the GLA is City Hall, Southwark; the mayor is Boris Johnson. The mayor's statutory planning strategy is published as the London Plan, which was most recently revised in 2011. The local authorities are the councils of the 32 London boroughs and the City of London Corporation. They are responsible for most local services, such as local planning, schools, social services, local roads and refuse collection. Certain functions, such as waste management, are provided through joint arrangements. In 2009–2010 the combined revenue expenditure by London councils and the GLA amounted to just over £22 billion (£14.7 billion for the boroughs and £7.4 billion for the GLA).
Is there an answer to this question: What group of elected officials provides checks and balances on the Mayor's executive authority?

Answer:
the London Assembly
