Ex Input:
What was formed in 1850 to help with policing?, Context: In the American Old West, policing was often of very poor quality.[citation needed] The Army often provided some policing alongside poorly resourced sheriffs and temporarily organized posses.[citation needed] Public organizations were supplemented by private contractors, notably the Pinkerton National Detective Agency, which was hired by individuals, businessmen, local governments and the federal government. At its height, the Pinkerton Agency's numbers exceeded those of the United States Army.[citation needed]

Ex Output:
Pinkerton National Detective Agency


Ex Input:
Why was Bell so inspired to do research on hearing and speech?, Context: 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]

Ex Output:
Bell's father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf


Ex Input:
What are the most recent versifications of the prayer?, Context: Luther's 1538 hymnic version of the Lord's Prayer, "Vater unser im Himmelreich", corresponds exactly to Luther's explanation of the prayer in the Small Catechism, with one stanza for each of the seven prayer petitions, plus opening and closing stanzas. The hymn functioned both as a liturgical setting of the Lord's Prayer and as a means of examining candidates on specific catechism questions. The extant manuscript shows multiple revisions, demonstrating Luther's concern to clarify and strengthen the text and to provide an appropriately prayerful tune. Other 16th- and 20th-century versifications of the Lord's Prayer have adopted Luther's tune, although modern texts are considerably shorter.

Ex Output:

20th-century
