Problem: Molotov%E2%80%93Ribbentrop Pact:

On 10 January 1941, Germany and the Soviet Union signed an agreement settling several ongoing issues. Secret protocols in the new agreement modified the "Secret Additional Protocols" of the GermanSoviet Boundary and Friendship Treaty, ceding the Lithuanian Strip to the Soviet Union in exchange for 7.5 million dollars (31.5 million Reichsmark). The agreement formally set the border between Germany and the Soviet Union between the Igorka river and the Baltic Sea. It also extended trade regulation of the 1940 GermanSoviet Commercial Agreement until August 1, 1942, increased deliveries above the levels of year one of that agreement, settled trading rights in the Baltics and Bessarabia, calculated the compensation for German property interests in the Baltic States now occupied by the Soviets and other issues. It also covered the migration to Germany within two and a half months of ethnic Germans and German citizens in Soviet-held Baltic territories, and the migration to the Soviet Union of Baltic and "White Russian" "nationals" in German-held territories.

Problem: Northwestern's Evanston campus, where the undergraduate schools, the Graduate School, and the Kellogg School of Management are located, runs north-south from Lincoln Avenue to Clark Street west of Lake Michigan along Sheridan Road. North and South Campuses have noticeably different atmospheres, owing to the predominance of Science and Athletics in the one and Humanities and Arts in the other. North Campus is home to the fraternity quads, the Henry Crown Sports Pavilion and Norris Aquatics Center and other athletic facilities, the Technological Institute, Dearborn Observatory, and other science-related buildings including Patrick G. and Shirley W. Ryan Hall for Nanofabrication and Molecular Self-Assembly, and the Ford Motor Company Engineering Design Center. South Campus is home to the University's humanities buildings, Pick-Staiger Concert Hall and other music buildings, the Mary and Leigh Block Museum of Art, and the sorority quads. In the 1960s, the University created an additional 84 acres (34.0 ha) by means of a lakefill in Lake Michigan. Among some of the buildings located on these broad new acres are University Library, Norris University Center (the student union), and Pick-Staiger Concert Hall.
Which campus holds the undergraduate schools, the Graduate school, and the Kellogg school of Management?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The term "Late Middle Ages" refers to one of the three periods of the Middle Ages, along with the Early Middle Ages and the High Middle Ages. Leonardo Bruni was the first historian to use tripartite periodization in his History of the Florentine People (1442). Flavio Biondo used a similar framework in Decades of History from the Deterioration of the Roman Empire (14391453). Tripartite periodization became standard after the German historian Christoph Cellarius published Universal History Divided into an Ancient, Medieval, and New Period (1683).
Along with the Late Middle Ages, what are the other three period of the Middle Ages?
A: unanswerable

Context and question: Persistent heavy rain and landslides in Wenchuan County and the nearby area badly affected rescue efforts. At the start of rescue operations on May 12, 20 helicopters were deployed for the delivery of food, water, and emergency aid, and also the evacuation of the injured and reconnaissance of quake-stricken areas. By 17:37 CST on May 13, a total of over 15,600 troops and militia reservists from the Chengdu Military Region had joined the rescue force in the heavily affected areas. A commander reported from Yingxiu Town, Wenchuan, that around 3,000 survivors were found, while the status of the other inhabitants (around 9,000) remained unclear. The 1,300 rescuers reached the epicenter, and 300 pioneer troops reached the seat of Wenchuan at about 23:30 CST. By 12:17 CST, May 14, 2008, communication in the seat of Wenchuan was partly revived. On the afternoon of May 14, 15 Special Operations Troops, along with relief supplies and communications gear, parachuted into inaccessible Mao County, northeast of Wenchuan.
How many helicopters were deployed?
Answer: 20

Question: The Han-era Chinese used bronze and iron to make a range of weapons, culinary tools, carpenters' tools and domestic wares. A significant product of these improved iron-smelting techniques was the manufacture of new agricultural tools. The three-legged iron seed drill, invented by the 2nd century BC, enabled farmers to carefully plant crops in rows instead of casting seeds out by hand. The heavy moldboard iron plow, also invented during the Han dynasty, required only one man to control it, two oxen to pull it. It had three plowshares, a seed box for the drills, a tool which turned down the soil and could sow roughly 45,730 m2 (11.3 acres) of land in a single day.
Is there an answer to this question: How many acres of land could succesfully be sowed with a seed box in a day?

Answer: 11.3 acres

QUES: TCM regularly airs a "Star of the Month" throughout the year on Wednesdays starting at 8:00 p.m. Eastern Time, in which most, if not all, feature films from a classic film star are shown during that night's schedule. Hosted by Robert Osbourne, the network also marks the occurrence of a film actor's birthday (either antemortem or posthumously) or recent death with day- or evening-long festivals showcasting several of that artist's best, earliest or least-known pictures; by effect, marathons scheduled in honor of an actor's passing (which are scheduled within a month after their death) pre-empt films originally scheduled to air on that date. TCM also features a monthly program block called the "TCM Guest Programmer", in which Osborne is joined by celebrity guests responsible for choosing that evening's films (examples of such programmers during 2012 include Jules Feiffer, Anthony Bourdain, Debra Winger, Ellen Barkin, Spike Lee, Regis Philbin and Jim Lehrer); an offshoot of this block featuring Turner Classic Movies employees aired during February 2011.
