Here is a question about this article: From the 8th to the 10th century, three dynasties contested for control of northern India: the Gurjara Pratiharas of Malwa, the Palas of Bengal, and the Rashtrakutas of the Deccan. The Sena dynasty would later assume control of the Pala Empire, and the Gurjara Pratiharas fragmented into various states. These were the first of the Rajput states. The first recorded Rajput kingdoms emerged in Rajasthan in the 6th century, and small Rajput dynasties later ruled much of northern India. One Gurjar Rajput of the Chauhan clan, Prithvi Raj Chauhan, was known for bloody conflicts against the advancing Turkic sultanates. The Chola empire emerged as a major power during the reign of Raja Raja Chola I and Rajendra Chola I who successfully invaded parts of Southeast Asia and Sri Lanka in the 11th century. Lalitaditya Muktapida (r. 724 CE–760 CE) was an emperor of the Kashmiri Karkoṭa dynasty, which exercised influence in northwestern India from 625 CE until 1003, and was followed by Lohara dynasty. He is known primarily for his successful battles against the Muslim and Tibetan advances into Kashmiri-dominated regions. Kalhana in his Rajatarangini credits king Lalitaditya with leading an aggressive military campaign in Northern India and Central Asia. He broke into the Uttarapatha and defeated the rebellious tribes of the Kambojas, Tukharas (Turks in Turkmenistan and Tocharians in Badakhshan), Bhautas (Tibetans in Baltistan and Tibet) and Daradas (Dards). His campaign then led him to subjugate the kingdoms of Pragjyotisha, Strirajya and the Uttarakurus. The Shahi dynasty ruled portions of eastern Afghanistan, northern Pakistan, and Kashmir from the mid-7th century to the early 11th century.
What is the answer to this question: In what century did the Chola Empire emerge?
****
So... 11th century


The problem: Answer a question about this article:
In the post-apartheid era, the Constitution of South Africa has declared the country to be a "Non-racial democracy". In an effort to redress past injustices, the ANC government has introduced laws in support of affirmative action policies for Blacks; under these they define "Black" people to include "Africans", "Coloureds" and "Asians". Some affirmative action policies favor "Africans" over "Coloureds" in terms of qualifying for certain benefits. Some South Africans categorized as "African Black" say that "Coloureds" did not suffer as much as they did during apartheid. "Coloured" South Africans are known to discuss their dilemma by saying, "we were not white enough under apartheid, and we are not black enough under the ANC (African National Congress)".[citation needed]
Who does the term "black" people include?
****
The answer: "Africans", "Coloureds" and "Asians"


Problem: Please answer a question about the following article about MP3:
The initial near-complete MPEG-1 standard (parts 1, 2 and 3) was publicly available on 6 December 1991 as ISO CD 11172. In most countries, patents cannot be filed after prior art has been made public, and patents expire 20 years after the initial filing date, which can be up to 12 months later for filings in other countries. As a result, patents required to implement MP3 expired in most countries by December 2012, 21 years after the publication of ISO CD 11172.
How long can it take for patents to be approved after initially being filed?
A: 12 months


Question: Read this and answer the question

Melatonin is absent from the system or undetectably low during daytime. Its onset in dim light, dim-light melatonin onset (DLMO), at roughly 21:00 (9 p.m.) can be measured in the blood or the saliva. Its major metabolite can also be measured in morning urine. Both DLMO and the midpoint (in time) of the presence of the hormone in the blood or saliva have been used as circadian markers. However, newer research indicates that the melatonin offset may be the more reliable marker. Benloucif et al. found that melatonin phase markers were more stable and more highly correlated with the timing of sleep than the core temperature minimum. They found that both sleep offset and melatonin offset are more strongly correlated with phase markers than the onset of sleep. In addition, the declining phase of the melatonin levels is more reliable and stable than the termination of melatonin synthesis.

When is the melatonin onset?
Answer: 9 p.m


Problem: Comcast has also earned a reputation for being anti-union. According to one of the company's training manuals, "Comcast does not feel union representation is in the best interest of its employees, customers, or shareholders". A dispute in 2004 with CWA, a labor union that represented many employees at Comcast's offices in Beaverton, Oregon, led to allegations of management intimidating workers, requiring them to attend anti-union meetings and unwarranted disciplinary action for union members. In 2011, Comcast received criticism from Writers Guild of America for its policies in regards to unions.
In what internal publication was Comcast's union stance formally enumerated?
The answer is the following: one of the company's training manuals

It overtook South Africa to become Africa's largest economy in 2014. Also, the debt-to-GDP ratio is only 11 percent, which is 8 percent below the 2012 ratio. Nigeria is considered to be an emerging market by the World Bank; It has been identified as a regional power on the African continent, a middle power in international affairs, and has also been identified as an emerging global power. Nigeria is a member of the MINT group of countries, which are widely seen as the globe's next "BRIC-like" economies. It is also listed among the "Next Eleven" economies set to become among the biggest in the world. Nigeria is a founding member of the Commonwealth of Nations, the African Union, OPEC, and the United Nations amongst other international organisations.

Now answer this question: What is Nigeria's 2015 purchasing power parity?

Output:
$1 trillion
