Problem: Kievan Rus%27:

The change in political structure led to the inevitable development of the peasant class or smerdy. The smerdy were free un-landed people that found work by labouring for wages on the manors which began to develop around 1031 as the verv' began to dominate socio-political structure. The smerdy were initially given equality in the Kievian law code, they were theoretically equal to the prince, so they enjoyed as much freedom as can be expected of manual labourers. However, in the 13th century they began to slowly lose their rights and became less equal in the eyes of the law.

Who was not given equality in the Kievian law code?
---
A: unanswerable


Problem: The Legend of Zelda: Twilight Princess:

Following the discovery of a buffer overflow vulnerability in the Wii version of Twilight Princess, an exploit known as the "Twilight Hack" was developed, allowing the execution of custom code from a Secure Digital (SD) card on the console. A properly designed save file would cause the game to load unsigned code, which could include Executable and Linkable Format (ELF) programs and homebrew Wii applications. Versions 3.3 and 3.4 of the Wii Menu prevented copying exploited save files onto the console until circumvention methods were discovered, and version 4.0 of the Wii Menu patched the vulnerability.

What kind of error was found in Twilight Princess for SD?
---
A: unanswerable


Problem: MP3:

In 1991, there were only two proposals available that could be completely assessed for an MPEG audio standard: Musicam (Masking pattern adapted Universal Subband Integrated Coding And Multiplexing) and ASPEC (Adaptive Spectral Perceptual Entropy Coding). The Musicam technique, as proposed by Philips (the Netherlands), CCETT (France) and Institut für Rundfunktechnik (Germany) was chosen due to its simplicity and error robustness, as well as its low computational power associated with the encoding of high quality compressed audio. The Musicam format, based on sub-band coding, was the basis of the MPEG Audio compression format (sampling rates, structure of frames, headers, number of samples per frame).

The Musicam format was proposed by Philips, based in which country?
---
A: Netherlands


Problem: History of India:

The most significant event between the 7th and 11th century was the Tripartite struggle centered on Kannauj that lasted for more than two centuries between the Pala Empire, Rashtrakuta Empire, and Gurjara Pratihara Empire. Southern India was ruled by the Chalukya, Chola, Pallava, Chera, Pandyan, and Western Chalukya Empires. The seventh century also saw the advent of Islam as a political power, though as a fringe, in the western part of the subcontinent, in modern-day Pakistan. The Chola dynasty conquered southern India and successfully invaded parts of Southeast Asia, Sri Lanka, Maldives and Bengal in the 11th century. The early medieval period Indian mathematics influenced the development of mathematics and astronomy in the Arab world and the Hindu numerals were introduced.

What dynasty conquered southern India and parts of southeast Asia?
---
A:
Chola dynasty
