Problem: Protestantism:

In European countries which were most profoundly influenced by the Reformation, Protestantism still remains the most practiced religion. These include the Nordic countries and the United Kingdom. In other historical Protestant strongholds such as Germany, the Netherlands, Switzerland, Latvia, Estonia and Hungary, it remains one of the most popular religions. Although Czech Republic was the site of one of the most significant pre-reformation movements, there are only few Protestant adherents; mainly due to historical reasons like persecution of Protestants by the Catholic Habsburgs, restrictions during the Communist rule, and also the ongoing secularization. Over the last several decades, religious practice has been declining as secularization has increased. According to a 2012 study about Religiosity in the European Union in 2012 by Eurobarometer, Protestants made up 12% of the EU population. According to Pew Research Center, Protestants constituted nearly one fifth (or 17.8%) of the continent's Christian population in 2010. Clarke and Beyer estimate that Protestants constituted 15% of all Europeans in 2009, while Noll claims that less than 12% of them lived in Europe in 2010.

The Pew Research Center estimated Protestants to be what percentage of Europe's Christian population in 2010?

A: 17.8%

Problem: John, King of England:

The character of John's relationship with his second wife, Isabella of Angouleme, is unclear. John married Isabella whilst she was relatively young her exact date of birth is uncertain, and estimates place her between at most 15 and more probably towards nine years old at the time of her marriage.[nb 15] Even by the standards of the time, Isabella was married whilst very young. John did not provide a great deal of money for his wife's household and did not pass on much of the revenue from her lands, to the extent that historian Nicholas Vincent has described him as being "downright mean" towards Isabella. Vincent concluded that the marriage was not a particularly "amicable" one. Other aspects of their marriage suggest a closer, more positive relationship. Chroniclers recorded that John had a "mad infatuation" with Isabella, and certainly John had conjugal relationships with Isabella between at least 1207 and 1215; they had five children. In contrast to Vincent, historian William Chester Jordan concludes that the pair were a "companionable couple" who had a successful marriage by the standards of the day.

How many children did John and Isabella have?
---
A: five children

Problem: Cardinal (Catholicism):

Cardinals have in canon law a "privilege of forum" (i.e., exemption from being judged by ecclesiastical tribunals of ordinary rank): only the pope is competent to judge them in matters subject to ecclesiastical jurisdiction (cases that refer to matters that are spiritual or linked with the spiritual, or with regard to infringement of ecclesiastical laws and whatever contains an element of sin, where culpability must be determined and the appropriate ecclesiastical penalty imposed). The pope either decides the case himself or delegates the decision to a tribunal, usually one of the tribunals or congregations of the Roman Curia. Without such delegation, no ecclesiastical court, even the Roman Rota, is competent to judge a canon law case against a cardinal. Cardinals are, however, subject to the civil and criminal law like everybody else.

Who is the only person who can judge a Cardinal in regards to laws of the church?
---
A: the pope

Problem: Alexander Graham Bell:

Bell's father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf, profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first U.S. patent for the telephone in 1876.[N 4] Bell considered his most famous invention an intrusion on his real work as a scientist and refused to have a telephone in his study.[N 5]

What did Bell never put in his study?
---
A:
telephone
