Problem: The success of its football team made Notre Dame a household name. The success of Note Dame reflected rising status of Irish Americans and Catholics in the 1920s. Catholics rallied up around the team and listen to the games on the radio, especially when it knocked off the schools that symbolized the Protestant establishment in America Harvard, Yale, Princeton, and Army. Yet this role as high-profile flagship institution of Catholicism made it an easy target of anti-Catholicism. The most remarkable episode of violence was the clash between Notre Dame students and the Ku Klux Klan in 1924. Nativism and anti-Catholicism, especially when directed towards immigrants, were cornerstones of the KKK's rhetoric, and Notre Dame was seen as a symbol of the threat posed by the Catholic Church. The Klan decided to have a week-long Klavern in South Bend. Clashes with the student body started on March 17, when students, aware of the anti-Catholic animosity, blocked the Klansmen from descending from their trains in the South Bend station and ripped the KKK clothes and regalia. On May 19 thousands of students massed downtown protesting the Klavern, and only the arrival of college president Fr. Matthew Walsh prevented any further clashes. The next day, football coach Knute Rockne spoke at a campus rally and implored the students to obey the college president and refrain from further violence. A few days later the Klavern broke up, but the hostility shown by the students was an omen and a contribution to the downfall of the KKK in Indiana.
Notre Dame students had a showdown in 1924 with which anti-catholic group?
The answer is the following: the Ku Klux Klan

Problem: Evidence suggests that blast furnaces, that convert raw iron ore into pig iron, which can be remelted in a cupola furnace to produce cast iron by means of a cold blast and hot blast, were operational in China by the late Spring and Autumn period (722481 BC). The bloomery was nonexistent in ancient China; however, the Han-era Chinese produced wrought iron by injecting excess oxygen into a furnace and causing decarburization. Cast iron and pig iron could be converted into wrought iron and steel using a fining process.
What can iron ore be converted into in a blast furnace?
The answer is the following: pig iron

Problem: What industries children work in depends on if they grew up in a rural area or an urban area. Children who were born in urban areas often found themselves working for street vendors, washing cars, helping in construction sites, weaving clothing, and sometimes even working as exotic dancers. While children who grew up in rural areas would work on farms doing physical labour, working with animals, and selling crops. Of all the child workers, the most serious cases involved street children and trafficked children due to the physical and emotional abuse they endured by their employers. To address the issue of child labour, the United Nations Conventions on the Rights of the Child Act was implemented in 1959. Yet due to poverty, lack of education and ignorance, the legal actions were not/are not wholly enforced or accepted in Africa.
What was the most serious aftereffects of child labour?
The answer is the following: physical and emotional abuse

Problem: Tuvalu consists of three reef islands and six true atolls. Its small, scattered group of atolls have poor soil and a total land area of only about 26 square kilometres (10 square miles) making it the fourth smallest country in the world. The islets that form the atolls are very low lying. Nanumanga, Niutao, Niulakita are reef islands and the six true atolls are Funafuti, Nanumea, Nui, Nukufetau, Nukulaelae and Vaitupu. Tuvalu's Exclusive Economic Zone (EEZ) covers an oceanic area of approximately 900,000 km2.
How does Tuvalu rank in country size as compared to other nations?
The answer is the following:
fourth smallest
