Example Input: After World War II, two new competing formats came onto the market and gradually replaced the standard "78": the 33 1⁄3 rpm (often just referred to as the 33 rpm), and the 45 rpm (see above). The 33 1⁄3 rpm LP (for "long-play") format was developed by Columbia Records and marketed in June 1948. RCA Victor developed the 45 rpm format and marketed it in March 1949, each pursuing their own r&d in secret. Both types of new disc used narrower grooves, intended to be played with smaller stylus—typically 0.001 inches (25 µm) wide, compared to 0.003 inches (76 µm) for a 78—so the new records were sometimes called Microgroove. In the mid-1950s all record companies agreed to a common recording standard called RIAA equalization. Prior to the establishment of the standard each company used its own preferred standard, requiring discriminating listeners to use pre-amplifiers with multiple selectable equalization curves.
Example Output: What two formats replaced the 78?

Example Input: Guinea-Bissau's GDP per capita is one of the lowest in the world, and its Human Development Index is one of the lowest on earth. More than two-thirds of the population lives below the poverty line. The economy depends mainly on agriculture; fish, cashew nuts and ground nuts are its major exports.
Example Output: How much of the population lives below the poverty line?

Example Input: The inhabitants of the British Isles have been drinking ale since the Bronze Age, but it was with the arrival of the Roman Empire in its shores in the 1st Century, and the construction of the Roman road networks that the first inns, called tabernae, in which travellers could obtain refreshment began to appear. After the departure of Roman authority in the 5th Century and the fall of the Romano-British kingdoms, the Anglo-Saxons established alehouses that grew out of domestic dwellings, the Anglo-Saxon alewife would put a green bush up on a pole to let people know her brew was ready. These alehouses quickly evolved into meeting houses for the folk to socially congregate, gossip and arrange mutual help within their communities. Herein lies the origin of the modern public house, or "Pub" as it is colloquially called in England. They rapidly spread across the Kingdom, becoming so commonplace that in 965 King Edgar decreed that there should be no more than one alehouse per village.
Example Output:
When did the inhabitants of the British Isles begin drinking ale?
