Problem: Tajikistan:

Russian border troops were stationed along the Tajik–Afghan border until summer 2005. Since the September 11, 2001 attacks, French troops have been stationed at the Dushanbe Airport in support of air operations of NATO's International Security Assistance Force in Afghanistan. United States Army and Marine Corps personnel periodically visit Tajikistan to conduct joint training missions of up to several weeks duration. The Government of India rebuilt the Ayni Air Base, a military airport located 15 km southwest of Dushanbe, at a cost of $70 million, completing the repairs in September 2010. It is now the main base of the Tajikistan air force. There have been talks with Russia concerning use of the Ayni facility, and Russia continues to maintain a large base on the outskirts of Dushanbe.

Why do US troops visit Tajikistan every so often?
---
A: to conduct joint training missions of up to several weeks duration.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In addition to re-writing the classification of annelids and 3 previously independent phyla, the molecular phylogenetics analyses undermine the emphasis that decades of previous writings placed on the importance of segmentation in the classification of invertebrates. Polychaetes, which these analyses found to be the parent group, have completely segmented bodies, while polychaetes' echiurans and sipunculan offshoots are not segmented and pogonophores are segmented only in the rear parts of their bodies. It now seems that segmentation can appear and disappear much more easily in the course of evolution than was previously thought. The 2007 study also noted that the ladder-like nervous system, which is associated with segmentation, is less universal previously thought in both annelids and arthropods.[n 2]
What nervous system structure is less universal among annelids than was thought before 1907?
A: unanswerable


Context and question: Cooperative breeding in birds typically occurs when offspring, usually males, delay dispersal from their natal group in order to remain with the family to help rear younger kin. Female offspring rarely stay at home, dispersing over distances that allow them to breed independently, or to join unrelated groups. In general, inbreeding is avoided because it leads to a reduction in progeny fitness (inbreeding depression) due largely to the homozygous expression of deleterious recessive alleles. Cross-fertilization between unrelated individuals ordinarily leads to the masking of deleterious recessive alleles in progeny.
What leads to the masking of deleterious recesive alleles in progeny?
Answer: Cross-fertilization between unrelated individuals


Question: On 1 April, Alexander addressed the Sénat conservateur. Long docile to Napoleon, under Talleyrand's prodding it had turned against him. Alexander told the Sénat that the Allies were fighting against Napoleon, not France, and they were prepared to offer honorable peace terms if Napoleon were removed from power. The next day, the Sénat passed the Acte de déchéance de l'Empereur ("Emperor's Demise Act"), which declared Napoleon deposed. Napoleon had advanced as far as Fontainebleau when he learned that Paris was lost. When Napoleon proposed the army march on the capital, his senior officers and marshals mutinied. On 4 April, led by Ney, they confronted Napoleon. Napoleon asserted the army would follow him, and Ney replied the army would follow its generals. While the ordinary soldiers and regimental officers wanted to fight on, without any senior officers or marshals any prospective invasion of Paris would have been impossible. Bowing to the inevitable, on 4 April Napoleon abdicated in favour of his son, with Marie-Louise as regent. However, the Allies refused to accept this under prodding from Alexander, who feared that Napoleon might find an excuse to retake the throne. Napoleon was then forced to announce his unconditional abdication only two days later.
Is there an answer to this question: Where had Napoleon advanced to when he received word that Paris was lost?

Answer: Fontainebleau


Question: During its formative period, the term madrasah referred to a higher education institution, whose curriculum initially included only the "religious sciences", whilst philosophy and the secular sciences were often excluded. The curriculum slowly began to diversify, with many later madaris teaching both the religious and the "secular sciences", such as logic, mathematics and philosophy. Some madaris further extended their curriculum to history, politics, ethics, music, metaphysics, medicine, astronomy and chemistry. The curriculum of a madrasah was usually set by its founder, but most generally taught both the religious sciences and the physical sciences. Madaris were established throughout the Islamic world, examples being the 9th century University of al-Qarawiyyin, the 10th century al-Azhar University (the most famous), the 11th century Niẓāmīyah, as well as 75 madaris in Cairo, 51 in Damascus and up to 44 in Aleppo between 1155 and 1260. Many more were also established in the Andalusian cities of Córdoba, Seville, Toledo, Granada (Madrasah of Granada), Murcia, Almería, Valencia and Cádiz during the Caliphate of Córdoba.
Is there an answer to this question: How many madaris have been founded in Cairo?

Answer:
75
