Problem: Northwestern has several housing options, including both traditional residence halls and residential colleges which gather together students who have a particular intellectual interest in common. Among the residential colleges are the Residential College of Cultural and Community Studies (CCS), Ayers College of Commerce and Industry, Jones Residential College (Arts), and Slivka Residential College (Science and Engineering). Dorms include 1835 Hinman, Bobb-McCulloch, Foster-Walker complex (commonly referred to as Plex), and several more. In Winter 2013, 39% of undergraduates were affiliated with a fraternity or sorority. Northwestern recognizes 21 fraternities and 18 sororities.
What percentage of undergraduates were affiliated with a fraternity or sorority in Winter 2013?
The answer is the following: 39%


In September 2013, West was widely rebuked by human rights groups for performing in Kazakhstan at the wedding of authoritarian President Nursultan Nazarbayev's grandson. He traveled to Kazakhstan, which has one of the poorest human rights records in the world, as a personal guest of Nazarbayev. Other notable Western performers, including Sting, have previously cancelled performances in the country over human rights concerns. West was reportedly paid US$3 million for his performance. West had previously participated in cultural boycotts, joining Shakira and Rage Against The Machine in refusing to perform in Arizona after the 2010 implementation of stop and search laws directed against potential illegal aliens.
Kanye, Shakira, and Rage Against the Machine refused to perform in what state due to a new law against illegal aliens?
Arizona


Input: Charleston, South Carolina
Violent incidents occurred throughout the Piedmont of the state as white insurgents struggled to maintain white supremacy in the face of social changes after the war and granting of citizenship to freedmen by federal constitutional amendments. After former Confederates were allowed to vote again, election campaigns from 1872 on were marked by violent intimidation of blacks and Republicans by white Democratic paramilitary groups, known as the Red Shirts. Violent incidents took place in Charleston on King Street in September 6 and in nearby Cainhoy on October 15, both in association with political meetings before the 1876 election. The Cainhoy incident was the only one statewide in which more whites were killed than blacks. The Red Shirts were instrumental in suppressing the black Republican vote in some areas in 1876 and narrowly electing Wade Hampton as governor, and taking back control of the state legislature. Another riot occurred in Charleston the day after the election, when a prominent Republican leader was mistakenly reported killed.

The Cainhoy Incident occurred on what day?
Output: October 15


Input: Article: According to the Namibia Labour Force Survey Report 2012, conducted by the Namibia Statistics Agency, the country's unemployment rate is 27.4%. "Strict unemployment" (people actively seeking a full-time job) stood at 20.2% in 2000, 21.9% in 2004 and spiraled to 29.4% in 2008. Under a broader definition (including people that have given up searching for employment) unemployment rose to 36.7% in 2004. This estimate considers people in the informal economy as employed. Labour and Social Welfare Minister Immanuel Ngatjizeko praised the 2008 study as "by far superior in scope and quality to any that has been available previously", but its methodology has also received criticism.

Now answer this question: What is Namibian's unemployment rate?

Output: 27.4%


Article: In March 1861, Victoria's mother died, with Victoria at her side. Through reading her mother's papers, Victoria discovered that her mother had loved her deeply; she was heart-broken, and blamed Conroy and Lehzen for "wickedly" estranging her from her mother. To relieve his wife during her intense and deep grief, Albert took on most of her duties, despite being ill himself with chronic stomach trouble. In August, Victoria and Albert visited their son, the Prince of Wales, who was attending army manoeuvres near Dublin, and spent a few days holidaying in Killarney. In November, Albert was made aware of gossip that his son had slept with an actress in Ireland. Appalled, Albert travelled to Cambridge, where his son was studying, to confront him. By the beginning of December, Albert was very unwell. He was diagnosed with typhoid fever by William Jenner, and died on 14 December 1861. Victoria was devastated. She blamed her husband's death on worry over the Prince of Wales's philandering. He had been "killed by that dreadful business", she said. She entered a state of mourning and wore black for the remainder of her life. She avoided public appearances, and rarely set foot in London in the following years. Her seclusion earned her the nickname "widow of Windsor".

Question: What was Prince of Wales attending to in Dublin?
Ans: army manoeuvres


Input: Antenna (radio)
The phase of reflection of electromagnetic waves depends on the polarization of the incident wave. Given the larger refractive index of the ground (typically n=2) compared to air (n=1), the phase of horizontally polarized radiation is reversed upon reflection (a phase shift of  radians or 180°). On the other hand, the vertical component of the wave's electric field is reflected at grazing angles of incidence approximately in phase. These phase shifts apply as well to a ground modelled as a good electrical conductor.

What is the refractive index of air?
Output:
n=1
