Problem: History of India:

The Mesolithic period in the Indian subcontinent was followed by the Neolithic period, when more extensive settlement of the subcontinent occurred after the end of the last Ice Age approximately 12,000 years ago. The first confirmed semipermanent settlements appeared 9,000 years ago in the Bhimbetka rock shelters in modern Madhya Pradesh, India. Early Neolithic culture in South Asia is represented by the Bhirrana findings (7500 BCE) in Haryana, India & Mehrgarh findings (7000–9000 BCE) in Balochistan, Pakistan.

What happened in India during the Neolithic period?
---
A: extensive settlement


Problem: Greece:

The culture of Greece has evolved over thousands of years, beginning in Mycenaean Greece and continuing most notably into Classical Greece, through the influence of the Roman Empire and its Greek Eastern continuation, the Eastern Roman or Byzantine Empire. Other cultures and nations, such as the Latin and Frankish states, the Ottoman Empire, the Venetian Republic, the Genoese Republic, and the British Empire have also left their influence on modern Greek culture, although historians credit the Greek War of Independence with revitalising Greece and giving birth to a single, cohesive entity of its multi-faceted culture.

Where did Greece culture begin?
---
A: Mycenaean Greece


Problem: Buckingham Palace:

During World War I, the palace, then the home of King George V and Queen Mary, escaped unscathed. Its more valuable contents were evacuated to Windsor but the royal family remained in situ. The King imposed rationing at the palace, much to the dismay of his guests and household. To the King's later regret, David Lloyd George persuaded him to go further by ostentatiously locking the wine cellars and refraining from alcohol, to set a good example to the supposedly inebriated working class. The workers continued to imbibe and the King was left unhappy at his enforced abstinence. In 1938, the north-west pavilion, designed by Nash as a conservatory, was converted into a swimming pool.

What did the king increase consumption of during the war?
---
A: unanswerable


Problem: Treaty:

In international law and international relations, a protocol is generally a treaty or international agreement that supplements a previous treaty or international agreement. A protocol can amend the previous treaty, or add additional provisions. Parties to the earlier agreement are not required to adopt the protocol. Sometimes this is made clearer by calling it an "optional protocol", especially where many parties to the first agreement do not support the protocol.

A protocol may either amend a previous treaty or do what?
---
A:
add additional provisions
