Problem: Punjab, Pakistan:

Punjab during Mahabharata times was known as Panchanada. Punjab was part of the Indus Valley Civilization, more than 4000 years ago. The main site in Punjab was the city of Harrapa. The Indus Valley Civilization spanned much of what is today Pakistan and eventually evolved into the Indo-Aryan civilisation. The Vedic civilisation flourished along the length of the Indus River. This civilisation shaped subsequent cultures in South Asia and Afghanistan. Although the archaeological site at Harappa was partially damaged in 1857 when engineers constructing the Lahore-Multan railroad used brick from the Harappa ruins for track ballast, an abundance of artefacts have nevertheless been found. Punjab was part of the great ancient empires including the Gandhara Mahajanapadas, Achaemenids, Macedonians, Mauryas, Kushans, Guptas, and Hindu Shahi. It also comprised the Gujar empire for a period of time, otherwise known as the Gurjara-Pratihara empire. Agriculture flourished and trading cities (such as Multan and Lahore) grew in wealth.

When was the archaeological site at Harappa discovered?

Problem: The Taragaon Museum presents the modern history of the Kathmandu Valley. It seeks to document 50 years of research and cultural heritage conservation of the Kathmandu Valley, documenting what artists photographers architects anthropologists from abroad had contributed in the second half of the 20th century. The actual structure of the Museum showcases restoration and rehabilitation efforts to preserve the built heritage of Kathmandu. It was designed by Carl Pruscha (master-planner of the Kathmandy Valley ) in 1970 and constructed in 1971. Restoration works began in 2010 to rehabilitate the Taragaon hostel into the Taragaon Museum. The design uses local brick along with modern architectural design elements, as well as the use of circle, triangles and squares. The Museum is within a short walk from the Boudhnath stupa, which itself can be seen from the Museum tower.
What is the Taragaon Museum dedicated to?

Answer: modern history of the Kathmandu Valley


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Prior to Einstein's paper, electromagnetic radiation such as visible light was considered to behave as a wave: hence the use of the terms "frequency" and "wavelength" to characterise different types of radiation. The energy transferred by a wave in a given time is called its intensity. The light from a theatre spotlight is more intense than the light from a domestic lightbulb; that is to say that the spotlight gives out more energy per unit time and per unit space(and hence consumes more electricity) than the ordinary bulb, even though the colour of the light might be very similar. Other waves, such as sound or the waves crashing against a seafront, also have their own intensity. However, the energy account of the photoelectric effect didn't seem to agree with the wave description of light.
Prior to Einstein's work, light behavior was modeled as what?
A: a wave


Context and question: Coats of arms were very important to the Polish nobility. Its heraldic system evolved together with its neighbours in Central Europe, while differing in many ways from the heraldry of other European countries. Polish knighthood families had its counterparts, links or roots in Moravia (i.e. Poraj) and Germany (i.e. Junosza).
Where did polish knightshood originate?
Answer: Moravia (i.e. Poraj) and Germany


Question: A similar struggle began in India when the Government of India Act 1919 failed to satisfy demand for independence. Concerns over communist and foreign plots following the Ghadar Conspiracy ensured that war-time strictures were renewed by the Rowlatt Acts. This led to tension, particularly in the Punjab region, where repressive measures culminated in the Amritsar Massacre. In Britain public opinion was divided over the morality of the event, between those who saw it as having saved India from anarchy, and those who viewed it with revulsion. The subsequent Non-Co-Operation movement was called off in March 1922 following the Chauri Chaura incident, and discontent continued to simmer for the next 25 years.
Is there an answer to this question: What event stoked fears of communist plots in India?

Answer: the Ghadar Conspiracy

A study in 2007 by Mark Long, an economics professor at the University of Washington, demonstrated that the alternatives of affirmative action proved ineffective in restoring minority enrollment in public flagship universities in California, Texas, and Washington. More specifically, apparent rebounds of minority enrollment can be explained by increasing minority enrollment in high schools of those states, and the beneficiaries of class-based (not race) affirmative action would be white students. At the same time, affirmative action itself is both morally and materially costly: 52 percent of white populace (compared to 14 percent of black) thought it should be abolished, implying white distaste of using racial identity, and full-file review is expected to cost the universities an additional $1.5 million to $2 million per year, excluding possible cost of litigation.
Who would supposedly be the beneficiaries of a class-based style affirmative action?
A:
white students
