Problem: Atlantic City, New Jersey:

During this time, Atlantic City was under the mayoral reign of Edward L. Bader, known for his contributions to the construction, athletics and aviation of Atlantic City. Despite the opposition of many others, he purchased land that became the city's municipal airport and high school football stadium, both of which were later named Bader Field in his honor. He led the initiative, in 1923, to construct the Atlantic City High School at Albany and Atlantic Avenues. Bader, in November 1923, initiated a public referendum, during the general election, at which time residents approved the construction of a Convention Center. The city passed an ordinance approving a bond issue for $1.5 million to be used for the purchase of land for Convention Hall, now known as the Boardwalk Hall, finalized September 30, 1924. Bader was also a driving force behind the creation of the Miss America competition.

What three contributions to Atlantic City was Edward L. Bader known for?
---
A: construction, athletics and aviation


Problem: Child labour:

Biggeri and Mehrotra have studied the macroeconomic factors that encourage child labour. They focus their study on five Asian nations including India, Pakistan, Indonesia, Thailand and Philippines. They suggest that child labour is a serious problem in all five, but it is not a new problem. Macroeconomic causes encouraged widespread child labour across the world, over most of human history. They suggest that the causes for child labour include both the demand and the supply side. While poverty and unavailability of good schools explain the child labour supply side, they suggest that the growth of low-paying informal economy rather than higher paying formal economy is amongst the causes of the demand side. Other scholars too suggest that inflexible labour market, sise of informal economy, inability of industries to scale up and lack of modern manufacturing technologies are major macroeconomic factors affecting demand and acceptability of child labour.

Supply and what else causes child labour to still exist today?
---
A: demand


Problem: Egypt:

On 18 January 2014, the interim government instituted a new constitution following a referendum in which 98.1% of voters were supportive. Participation was low with only 38.6% of registered voters participating although this was higher than the 33% who voted in a referendum during Morsi's tenure. On 26 March 2014 Abdel Fattah el-Sisi the head of the Egyptian Armed Forces, who at this time was in control of the country, resigned from the military, announcing he would stand as a candidate in the 2014 presidential election. The poll, held between 26 and 28 May 2014, resulted in a landslide victory for el-Sisi. Sisi was sworn into office as President of Egypt on 8 June 2014. The Muslim Brotherhood and some liberal and secular activist groups boycotted the vote. Even though the military-backed authorities extended voting to a third day, the 46% turnout was lower than the 52% turnout in the 2012 election.

Who was elected President in 2014?
---
A: Abdel Fattah el-Sisi


Problem: Group (mathematics):

Finite symmetry groups such as the Mathieu groups are used in coding theory, which is in turn applied in error correction of transmitted data, and in CD players. Another application is differential Galois theory, which characterizes functions having antiderivatives of a prescribed form, giving group-theoretic criteria for when solutions of certain differential equations are well-behaved.u[›] Geometric properties that remain stable under group actions are investigated in (geometric) invariant theory.

What is used for error correction of transferred data?
---
A:
coding theory
