Problem: 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.

Leaving Sirte, what valley did Gaddafi hope to travel to?
---
A: Jarref

Context and question: During the SNES's life, Nintendo contracted with two different companies to develop a CD-ROM-based peripheral for the console to compete with Sega's CD-ROM based addon, Mega-CD. Ultimately, deals with both Sony and Philips fell through, (although a prototype console was produced by Sony) with Philips gaining the right to release a series of titles based on Nintendo franchises for its CD-i multimedia player and Sony going on to develop its own console based on its initial dealings with Nintendo (the PlayStation).
What was Sega's CD add-on?
Answer: Mega-CD

Question: In his 1805 mandolin method, Anweisung die Mandoline von selbst zu erlernen nebst einigen Uebungsstucken von Bortolazzi, Bartolomeo Bortolazzi popularised the Cremonese mandolin, which had four single-strings and a fixed bridge, to which the strings were attached. Bortolazzi said in this book that the new wire strung mandolins were uncomfortable to play, when compared with the gut-string instruments. Also, he felt they had a "less pleasing...hard, zither-like tone" as compared to the gut string's "softer, full-singing tone." He favored the four single strings of the Cremonese instrument, which were tuned the same as the Neapolitan.
Is there an answer to this question: How many double strings did the Cremonese Mandolin have?

Answer: unanswerable

Early during the Taiping Rebellion, Qing forces suffered a series of disastrous defeats culminating in the loss of the regional capital city of Nanjing in 1853. Shortly thereafter, a Taiping expeditionary force penetrated as far north as the suburbs of Tianjin, the imperial heartlands. In desperation the Qing court ordered a Chinese official, Zeng Guofan, to organize regional and village militias into an emergency army called tuanlian. Zeng Guofan's strategy was to rely on local gentry to raise a new type of military organization from those provinces that the Taiping rebels directly threatened. This new force became known as the Xiang Army, named after the Hunan region where it was raised. The Xiang Army was a hybrid of local militia and a standing army. It was given professional training, but was paid for out of regional coffers and funds its commanders mostly members of the Chinese gentry could muster. The Xiang Army and its successor, the Huai Army, created by Zeng Guofan's colleague and mentee Li Hongzhang, were collectively called the "Yong Ying" (Brave Camp).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What city did the Qing lose in 1853?
Ah, so..
Nanjing
