Ethnic tensions had escalated between the Armenians and Azerbaijanis in spring and summer 1988. On January 9, 1990, after the Armenian parliament voted to include Nagorno-Karabakh within its budget, renewed fighting broke out, hostages were taken, and four Soviet soldiers were killed. On January 11, Popular Front radicals stormed party buildings and effectively overthrew the communist powers in the southern town of Lenkoran. Gorbachev resolved to regain control of Azerbaijan; the events that ensued are known as "Black January." Late on January 19, 1990, after blowing up the central television station and cutting the phone and radio lines, 26,000 Soviet troops entered the Azerbaijani capital Baku, smashing barricades, attacking protesters, and firing into crowds. On that night and during subsequent confrontations (which lasted until February), more than 130 people died the majority of whom were civilians. More than 700 civilians were wounded, hundreds were detained, but only a few were actually tried for alleged criminal offenses.

How many Soviet troops occupied Baku?
Answer: 26,000

Problem: One hundred years after the fall of Constantinople in 1453, Pierre Belon described in his work Observations in 1553 that pissasphalto, a mixture of pitch and bitumen, was used in Dubrovnik for tarring of ships from where it was exported to a market place in Venice where it could be bought by anyone. An 1838 edition of Mechanics Magazine cites an early use of asphalt in France. A pamphlet dated 1621, by "a certain Monsieur d'Eyrinys, states that he had discovered the existence (of asphaltum) in large quantities in the vicinity of Neufchatel", and that he proposed to use it in a variety of ways "principally in the construction of air-proof granaries, and in protecting, by means of the arches, the water-courses in the city of Paris from the intrusion of dirt and filth", which at that time made the water unusable. "He expatiates also on the excellence of this material for forming level and durable terraces" in palaces, "the notion of forming such terraces in the streets not one likely to cross the brain of a Parisian of that generation". But it was generally neglected in France until the revolution of 1830. Then, in the 1830s, there was a surge of interest, and asphalt became widely used "for pavements, flat roofs, and the lining of cisterns, and in England, some use of it had been made of it for similar purposes". Its rise in Europe was "a sudden phenomenon", after natural deposits were found "in France at Osbann (BasRhin), the Parc (l'Ain) and the Puy-de-la-Poix (Puy-de-Dome)", although it could also be made artificially. One of the earliest uses in France was the laying of about 24,000 square yards of Seyssel asphalt at the Place de la Concorde in 1835.
After what event in France did asphalt begin to be used for pavements and assorted other uses?
The answer is the following: revolution of 1830

Input: Muammar Gaddafi
Only a few towns in western Libyasuch as Bani Walid, Sebha and Sirteremained Gaddafist strongholds. Retreating to Sirte after Tripoli's fall, Gaddafi announced his willingness to negotiate for a handover to a transitional government, a suggestion rejected by the NTC. Surrounding himself with bodyguards, he continually moved residences to escape NTC shelling, devoting his days to prayer and reading the Qur'an. On 20 October, Gaddafi broke out of Sirte's District 2 in a joint civilian-military convoy, hoping to take refuge in the Jarref Valley. At around 8.30am, NATO bombers attacked, destroying at least 14 vehicles and killing at least 53. The convoy scattered, and Gaddafi and those closest to him fled to a nearby villa, which was shelled by rebel militia from Misrata. Fleeing to a construction site, Gaddafi and his inner cohort hid inside drainage pipes while his bodyguards battled the rebels; in the conflict, Gaddafi suffered head injuries from a grenade blast while defence minister Abu-Bakr Yunis Jabr was killed.

After fleeing to a construction site, how was Gaddafi injured?
Output: grenade blast

Input: Article: On March 26, 1913, Venustiano Carranza issued the Plan de Guadalupe, which refused to recognize Huerta as president and called for war between the two factions. Soon after the assassination of President Madero, Carranza returned to Mexico to fight Huerta, but with only a handful of comrades. However, by 1913 his forces had swelled into an army of thousands, called the Division del Norte (Northern Division). Villa and his army, along with Emiliano Zapata and Alvaro Obregon, united with Carranza to fight against Huerta. In March 1914 Carranza traveled to Ciudad Juarez, which served as rebellion's capital for the remainder of the struggle with Huerta. In April 1914 U.S. opposition to Huerta had reached its peak, blockading the regime's ability to resupply from abroad. Carranza trying to keep his nationalistic credentials threatened war with the United States. In his spontaneous response to U.S. President Woodrow Wilson Carranza asked "that the president withdraw American troops from Mexico."

Now answer this question: The Plan de Guadalupe refused to recognize who as the president?

Output: Huerta
