Problem: Please answer a question about the following article about Child labour:
In European history when child labour was common, as well as in contemporary child labour of modern world, certain cultural beliefs have rationalised child labour and thereby encouraged it. Some view that work is good for the character-building and skill development of children. In many cultures, particular where the informal economy and small household businesses thrive, the cultural tradition is that children follow in their parents' footsteps; child labour then is a means to learn and practice that trade from a very early age. Similarly, in many cultures the education of girls is less valued or girls are simply not expected to need formal schooling, and these girls pushed into child labour such as providing domestic services.
Are boys or girls more likely in some cultures to be thrown into child labour?
A: girls

Problem: Please answer a question about the following article about Mandolin:
Jethro Burns, best known as half of the comedy duo Homer and Jethro, was also the first important jazz mandolinist. Tiny Moore popularized the mandolin in Western swing music. He initially played an 8-string Gibson but switched after 1952 to a 5-string solidbody electric instrument built by Paul Bigsby. Modern players David Grisman, Sam Bush, and Mike Marshall, among others, have worked since the early 1970s to demonstrate the mandolin's versatility for all styles of music. Chris Thile of California is a well-known player, and has accomplished many feats of traditional bluegrass, classical, contemporary pop and rock; the band Nickel Creek featured his playing in its blend of traditional and pop styles, and he now plays in his band Punch Brothers. Most commonly associated with bluegrass, mandolin has been used a lot in country music over the years. Some well-known players include Marty Stuart, Vince Gill, and Ricky Skaggs.
What type of music did Jethro Burns play? 
A: jazz mandolinist
Problem: Please answer a question about the following article about Modern history:
At the time of the Berlin Conference, Africa contained one-fifth of the world’s population living in one-quarter of the world’s land area. However, from Europe's perspective, they were dividing an unknown continent. European countries established a few coastal colonies in Africa by the mid-nineteenth century, which included Cape Colony (Great Britain), Angola (Portugal), and Algeria (France), but until the late nineteenth century Europe largely traded with free African states without feeling the need for territorial possession. Until the 1880s most of Africa remained unchartered, with western maps from the period generally showing blank spaces for the continent’s interior.
What percent of the worlds population did Africa posses at the Berlin Conference?
A:
one-fifth
