Input: Read this: In the U.S., copyright infringement is sometimes confronted via lawsuits in civil court, against alleged infringers directly, or against providers of services and software that support unauthorized copying. For example, major motion-picture corporation MGM Studios filed suit against P2P file-sharing services Grokster and Streamcast for their contributory role in copyright infringement. In 2005, the Supreme Court ruled in favor of MGM, holding that such services could be held liable for copyright infringement since they functioned and, indeed, willfully marketed themselves as venues for acquiring copyrighted movies. The MGM v. Grokster case did not overturn the earlier Sony decision, but rather clouded the legal waters; future designers of software capable of being used for copyright infringement were warned.

Input: Read this: A similar fate befell the Curonians who lived in the area around the Curonian Lagoon. While many fled from the Red Army during the evacuation of East Prussia, Curonians that remained behind were subsequently expelled by the Soviet Union. Only 219 lived along the Curonian Spit in 1955. Many had German names such as Fritz or Hans, a cause for anti-German discrimination. The Soviet authorities considered the Curonians fascists. Because of this discrimination, many immigrated to West Germany in 1958, where the majority of Curonians now live.
Question: How many Curonians were left behind after many immigrated to West Germany in 1958?

Output: unanswerable

Input: Read this: 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.
Question: What ancient civilization lived in Punjab?
