Problem: Muammar Gaddafi:

Gaddafi married his first wife, Fatiha al-Nuri, in 1969. She was the daughter of General Khalid, a senior figure in King Idris' administration, and was from a middle-class background. Although they had one son, Muhammad Gaddafi (b. 1970), their relationship was strained, and they divorced in 1970. Gaddafi's second wife was Safia Farkash, née el-Brasai, a former nurse from Obeidat tribe born in Bayda. They met in 1969, following his ascension to power, when he was hospitalized with appendicitis; he claimed that it was love at first sight. The couple remained married until his death. Together they had seven biological children: Saif al-Islam Gaddafi (b. 1972), Al-Saadi Gaddafi (b. 1973), Mutassim Gaddafi (1974–2011), Hannibal Muammar Gaddafi (b. 1975), Ayesha Gaddafi (b. 1976), Saif al-Arab Gaddafi (1982–2011), and Khamis Gaddafi (1983–2011). He also adopted two children, Hanna Gaddafi and Milad Gaddafi.

What tribe did Safia Farkash belong to?

A: Obeidat


Problem: Mexico City:

Diaz's plans called for the entire city to eventually be modernized or rebuilt in the Porfirian/French style of the Colonia Roma; but the Mexican Revolution began soon afterward and the plans never came to fruition, with many projects being left half-completed. One of the best examples of this is the Monument to the Mexican Revolution. Originally the monument was to be the main dome of Diaz's new senate hall, but when the revolution erupted only the dome of the senate hall and its supporting pillars were completed, this was subsequently seen as a symbol by many Mexicans that the Porfirian era was over once and for all and as such, it was turned into a monument to victory over Diaz.

What was turned into a monument after the war? 
---
A: the main dome of Diaz's new senate hall


Problem: Electric motor:

The brushless wound-rotor synchronous doubly-fed (BWRSDF) machine is the only electric machine with a truly dual ported transformer circuit topology (i.e., both ports independently excited with no short-circuited port). The dual ported transformer circuit topology is known to be unstable and requires a multiphase slip-ring-brush assembly to propagate limited power to the rotor winding set. If a precision means were available to instantaneously control torque angle and slip for synchronous operation during motoring or generating while simultaneously providing brushless power to the rotor winding set, the active current of the BWRSDF machine would be independent of the reactive impedance of the transformer circuit and bursts of torque significantly higher than the maximum operating torque and far beyond the practical capability of any other type of electric machine would be realizable. Torque bursts greater than eight times operating torque have been calculated.

What is the only device with triple ported transformer circuit topology?
---
A: unanswerable


Problem: Boston:

The city, especially the East Boston neighborhood, has a significant Hispanic community. Hispanics in Boston are mostly of Puerto Rican (30,506 or 4.9% of total city population), Dominican (25,648 or 4.2% of total city population), Salvadoran (10,850 or 1.8% of city population), Colombian (6,649 or 1.1% of total city population), Mexican (5,961 or 1.0% of total city population), and Guatemalan (4,451 or 0.7% of total city population) ethnic origin. When including all Hispanic national origins, they number 107,917. In Greater Boston, these numbers grow significantly with Puerto Ricans numbering 175,000+, Dominicans 95,000+, Salvadorans 40,000+, Guatemalans 31,000+, Mexicans 25,000+, and Colombians numbering 22,000+.

How many Puerto Rican hispanics live in greater Boston?

A:
175,000+
