Problem: Antarctica:

The main mineral resource known on the continent is coal. It was first recorded near the Beardmore Glacier by Frank Wild on the Nimrod Expedition, and now low-grade coal is known across many parts of the Transantarctic Mountains. The Prince Charles Mountains contain significant deposits of iron ore. The most valuable resources of Antarctica lie offshore, namely the oil and natural gas fields found in the Ross Sea in 1973. Exploitation of all mineral resources is banned until 2048 by the Protocol on Environmental Protection to the Antarctic Treaty.

What expedition discovered coal on Antarctica?

A: Nimrod Expedition


Problem: Igor returned to Kiev keen for revenge. He assembled a large force of warriors from among neighboring Slavs and Pecheneg allies, and sent for reinforcements of Varangians from “beyond the sea.” In 944 the Rus' force advanced again on the Greeks, by land and sea, and a Byzantine force from Cherson responded. The Emperor sent gifts and offered tribute in lieu of war, and the Rus' accepted. Envoys were sent between the Rus’, the Byzantines, and the Bulgarians in 945, and a peace treaty was completed. The agreement again focused on trade, but this time with terms less favorable to the Rus’, including stringent regulations on the conduct of Rus’ merchants in Cherson and Constantinople and specific punishments for violations of the law. The Byzantines may have been motivated to enter the treaty out of concern of a prolonged alliance of the Rus', Pechenegs, and Bulgarians against them, though the more favorable terms further suggest a shift in power.
What year did the Rus defeat the Byzantines the the Bulgarians?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Britain's fears of war with Germany were realised in 1914 with the outbreak of the First World War. Britain quickly invaded and occupied most of Germany's overseas colonies in Africa. In the Pacific, Australia and New Zealand occupied German New Guinea and Samoa respectively. Plans for a post-war division of the Ottoman Empire, which had joined the war on Germany's side, were secretly drawn up by Britain and France under the 1916 Sykes–Picot Agreement. This agreement was not divulged to the Sharif of Mecca, who the British had been encouraging to launch an Arab revolt against their Ottoman rulers, giving the impression that Britain was supporting the creation of an independent Arab state.
When WW1 began, Britain took the opportunity to take over most of which country's colonies?
A: Germany


Context and question: Persistent infections occur because the body is unable to clear the organism after the initial infection. Persistent infections are characterized by the continual presence of the infectious organism, often as latent infection with occasional recurrent relapses of active infection. There are some viruses that can maintain a persistent infection by infecting different cells of the body. Some viruses once acquired never leave the body. A typical example is the herpes virus, which tends to hide in nerves and become reactivated when specific circumstances arise.
What never leave the body when acquired?
Answer: Some viruses


Question: On 19 November 1968, following progressive economic decline, the Keïta regime was overthrown in a bloodless military coup led by Moussa Traoré, a day which is now commemorated as Liberation Day. The subsequent military-led regime, with Traoré as president, attempted to reform the economy. His efforts were frustrated by political turmoil and a devastating drought between 1968 to 1974, in which famine killed thousands of people. The Traoré regime faced student unrest beginning in the late 1970s and three coup attempts. The Traoré regime repressed all dissenters until the late 1980s.
Is there an answer to this question: What afflicted the country prior to 1968?

Answer: unanswerable


Problem: Pope John XXIII:

Maintaining continuity with his predecessors, John XXIII continued the gradual reform of the Roman liturgy, and published changes that resulted in the 1962 Roman Missal, the last typical edition containing the Tridentine Mass established in 1570 by Pope Pius V at the request of the Council of Trent and whose continued use Pope Benedict XVI authorized in 2007, under the conditions indicated in his motu proprio Summorum Pontificum. In response to the directives of the Second Vatican Council, later editions of the Roman Missal present the 1970 form of the Roman Rite.

What did Pope Pius V continue to authorize the use of in 2007?
