Problem: The Houston area has over 150 active faults (estimated to be 300 active faults) with an aggregate length of up to 310 miles (500 km), including the Long PointEureka Heights fault system which runs through the center of the city. There have been no significant historically recorded earthquakes in Houston, but researchers do not discount the possibility of such quakes having occurred in the deeper past, nor occurring in the future. Land in some areas southeast of Houston is sinking because water has been pumped out of the ground for many years. It may be associated with slip along the faults; however, the slippage is slow and not considered an earthquake, where stationary faults must slip suddenly enough to create seismic waves. These faults also tend to move at a smooth rate in what is termed "fault creep", which further reduces the risk of an earthquake.
How many estimated active faults does Houston have?

Answer: 300

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 1520% of active cases, the infection spreads outside the lungs, causing other kinds of TB. These are collectively denoted as "extrapulmonary tuberculosis". Extrapulmonary TB occurs more commonly in immunosuppressed persons and young children. In those with HIV, this occurs in more than 50% of cases. Notable extrapulmonary infection sites include the pleura (in tuberculous pleurisy), the central nervous system (in tuberculous meningitis), the lymphatic system (in scrofula of the neck), the genitourinary system (in urogenital tuberculosis), and the bones and joints (in Pott disease of the spine), among others. When it spreads to the bones, it is also known as "osseous tuberculosis", a form of osteomyelitis. Sometimes, bursting of a tubercular abscess through skin results in tuberculous ulcer. An ulcer originating from nearby infected lymph nodes is painless, slowly enlarging and has an appearance of "wash leather". A potentially more serious, widespread form of TB is called "disseminated tuberculosis", also known as miliary tuberculosis. Miliary TB makes up about 10% of extrapulmonary cases.
What percentage of young children get Extrapulmonary TB?
A: unanswerable

Context and question: ^Note 2: in 1789 the Georgia Constitution was amended as follows: "Article IV. Section 10.

Question: The views of the Church Fathers still play an important role in the shaping of Orthodox Marian perspective. However, the Orthodox views on Mary are mostly doxological, rather than academic: they are expressed in hymns, praise, liturgical poetry and the veneration of icons. One of the most loved Orthodox Akathists (i.e. standing hymns) is devoted to Mary and it is often simply called the Akathist Hymn. Five of the twelve Great Feasts in Orthodoxy are dedicated to Mary. The Sunday of Orthodoxy directly links the Virgin Mary's identity as Mother of God with icon veneration. A number of Orthodox feasts are connected with the miraculous icons of the Theotokos.
Is there an answer to this question: Who wrote the Akathist Hymn?

Answer: unanswerable

Problem: Muammar Gaddafi:

The Jamahiriya's radical direction earned the government many enemies. In February 1978, Gaddafi discovered that his head of military intelligence was plotting to kill him, and began to increasingly entrust security to his Qaddadfa tribe. Many who had seen their wealth and property confiscated turned against the administration, and a number of western-funded opposition groups were founded by exiles. Most prominent was the National Front for the Salvation of Libya (NFSL), founded in 1981 by Mohammed Magariaf, which orchestrated militant attacks against Libya's government, while another, al-Borkan, began killing Libyan diplomats abroad. Following Gaddafi's command to kill these "stray dogs", under Colonel Younis Bilgasim's leadership, the Revolutionary Committees set up overseas branches to suppress counter-revolutionary activity, assassinating various dissidents. Although nearby nations like Syria also used hit squads, Gaddafi was unusual in publicly bragging about his administration's use of them; in June 1980, he ordered all dissidents to return home or be "liquidated wherever you are."

What tribe did Gaddafi belong to?
---
A:
Qaddadfa
