Part 2. Example
Sentence: Namibia conducts a census every ten years. After independence the first Population and Housing Census was carried out in 1991, further rounds followed in 2001 and 2011. The data collection method is to count every person resident in Namibia on the census reference night, wherever they happen to be. This is called the de facto method. For enumeration purposes the country is demarcated into 4,042 enumeration areas. These areas do not overlap with constituency boundaries to get reliable data for election purposes as well.
Question: How often does Namibia conduct a census?
Answer: every ten years
Explanation: Census is generally conducted every ten years in most countries like Namibia.
Part 3. Exercise
Sentence: The mayor of Paris is elected indirectly by Paris voters; the voters of each arrondissement elect the Conseil de Paris (Council of Paris), composed of 163 members. Each arrondissement has a number of members depending upon its population, from 10 members for each of the least-populated arrondissements (1st through 9th) to 36 members for the most populated (the 15th). The elected council members select the mayor. Sometimes the candidate who receives the most votes city-wide is not selected if the other candidate has won the support of the majority of council members. Mayor Bertrand Delanoe (2001-2014) was elected by only a minority of city voters, but a majority of council members. Once elected, the council plays a largely passive role in the city government; it meets only once a month. The current council is divided between a coalition of the left of 91 members, including the socialists, communists, greens, and extreme left; and 71 members for the centre right, plus a few members from smaller parties.
Question: How often does the council meet?
Answer:
once a month
