Input: Madonna (entertainer)
Madonna embarked on the Confessions Tour in May 2006, which had a global audience of 1.2 million and grossed over $193.7 million, becoming the highest-grossing tour to that date for a female artist. Madonna used religious symbols, such as the crucifix and Crown of Thorns, in the performance of "Live to Tell". It caused the Russian Orthodox Church and the Federation of Jewish Communities of Russia to urge all their members to boycott her concert. At the same time, the International Federation of the Phonographic Industry (IFPI) announced officially that Madonna had sold over 200 million copies for her albums alone worldwide.

It was confirmed by IFPI that Madonna officially sold how many albums worldwide?

Input: Article: The Caribbean initially provided England's most important and lucrative colonies, but not before several attempts at colonisation failed. An attempt to establish a colony in Guiana in 1604 lasted only two years, and failed in its main objective to find gold deposits. Colonies in St Lucia (1605) and Grenada (1609) also rapidly folded, but settlements were successfully established in St. Kitts (1624), Barbados (1627) and Nevis (1628). The colonies soon adopted the system of sugar plantations successfully used by the Portuguese in Brazil, which depended on slave labour, and—at first—Dutch ships, to sell the slaves and buy the sugar. To ensure that the increasingly healthy profits of this trade remained in English hands, Parliament decreed in 1651 that only English ships would be able to ply their trade in English colonies. This led to hostilities with the United Dutch Provinces—a series of Anglo-Dutch Wars—which would eventually strengthen England's position in the Americas at the expense of the Dutch. In 1655, England annexed the island of Jamaica from the Spanish, and in 1666 succeeded in colonising the Bahamas.

Now answer this question: When did England first establish a colony in Guiana?

Output: 1604


Article: In 2005, the number of public employees per thousand inhabitants in the Portuguese government (70.8) was above the European Union average (62.4 per thousand inhabitants). By EU and USA standards, Portugal's justice system was internationally known as being slow and inefficient, and by 2011 it was the second slowest in Western Europe (after Italy); conversely, Portugal has one of the highest rates of judges and prosecutors—over 30 per 100,000 people. The entire Portuguese public service has been known for its mismanagement, useless redundancies, waste, excess of bureaucracy and a general lack of productivity in certain sectors, particularly in justice.

Question: What was the average number of public employees per every thousand inhabitants for the European Union in 2005?
Ans: 62.4


Here is a question about this article: The Houston area is a leading center for building oilfield equipment.

Houston is the beginning or end point of numerous oil, gas, and products pipelines:
What is the answer to this question: What has the Houston ship channel served to promote into success?

Although older German loanwords were colloquial, recent borrowings from other languages are associated with high culture.
