Input: Read this: About 98% of Antarctica is covered by the Antarctic ice sheet, a sheet of ice averaging at least 1.6 km (1.0 mi) thick. The continent has about 90% of the world's ice (and thereby about 70% of the world's fresh water). If all of this ice were melted, sea levels would rise about 60 m (200 ft). In most of the interior of the continent, precipitation is very low, down to 20 mm (0.8 in) per year; in a few "blue ice" areas precipitation is lower than mass loss by sublimation and so the local mass balance is negative. In the dry valleys, the same effect occurs over a rock base, leading to a desiccated landscape.
Question: What is, on average, 1.6 mi thick?

Output: unanswerable

Input: Read this: The music of the indigenous peoples of Central Mexico and Central America was often pentatonic. Before the arrival of the Spaniards and other Europeans, music was inseparable from religious festivities and included a large variety of percussion and wind instruments such as drums, flutes, sea snail shells (used as a trumpet) and "rain" tubes. No remnants of pre-Columbian stringed instruments were found until archaeologists discovered a jar in Guatemala, attributed to the Maya of the Late Classic Era (600900 CE), which depicts a stringed musical instrument which has since been reproduced. This instrument is one of the very few stringed instruments known in the Americas prior to the introduction of European musical instruments; when played it produces a sound virtually identical to a jaguar's growl.
Question: What role did music play in the religious festivities?

Output: inseparable from

Input: Read this: Anti-government protests in 1991 led to a coup, a transitional government, and a new constitution. Opposition to the corrupt and dictatorial regime of General Moussa Traore grew during the 1980s. During this time strict programs, imposed to satisfy demands of the International Monetary Fund, brought increased hardship upon the country's population, while elites close to the government supposedly lived in growing wealth. Peaceful student protests in January 1991 were brutally suppressed, with mass arrests and torture of leaders and participants. Scattered acts of rioting and vandalism of public buildings followed, but most actions by the dissidents remained nonviolent.
Question: In January of 1991 what type of protests were violently curbed?

Output: student protests

Prince Gong, a younger half-brother of the emperor, who had been left as his brother's proxy in the capital, was forced to sign the Convention of Beijing. Meanwhile, the humiliated emperor died the following year at Rehe.
Question: Whed did the British and French invade Beijing?

Output:
