Example Input: Passage: Much of the cuisine of former Ottoman territories today is descended from a shared Ottoman cuisine, especially Turkish cuisine, and including Greek cuisine, Balkan cuisine, Armenian cuisine, and Middle Eastern cuisine. Many common dishes in the region, descendants of the once-common Ottoman cuisine, include yogurt, döner kebab/gyro/shawarma, cacık/tzatziki, ayran, pita bread, feta cheese, baklava, lahmacun, moussaka, yuvarlak, köfte/keftés/kofta, börek/boureki, rakı/rakia/tsipouro/tsikoudia, meze, dolma, sarma, rice pilaf, Turkish coffee, sujuk, kashk, keşkek, manti, lavash, kanafeh, and more. Question: Turkish and Greek cuisine are descended from Ottoman Cuisine, along with the food of what other regions?

Example Input: Passage: In 2009 Tajikistan had 26 airports, 18 of which had paved runways, of which two had runways longer than 3,000 meters. The country's main airport is Dushanbe International Airport which as of April 2015, had regularly scheduled flights to major cities in Russia, Central Asia, as well as Delhi, Dubai, Frankfurt, Istanbul, Kabul, Tehran, and Ürümqi amongst others. There are also international flights, mainly to Russia, from Khujand Airport in the northern part of the country as well as limited international services from Kulob Airport, and Qurghonteppa International Airport. Khorog Airport is a domestic airport and also the only airport in the sparsely populated eastern half of the country. Question: Where are the international flights maining going to?
Example Output: Russia

Example Input: Passage: In 2007 Torsten Struck and colleagues compared 3 genes in 81 taxa, of which 9 were outgroups, in other words not considered closely related to annelids but included to give an indication of where the organisms under study are placed on the larger tree of life. For a cross-check the study used an analysis of 11 genes (including the original 3) in 10 taxa. This analysis agreed that clitellates, pogonophorans and echiurans were on various branches of the polychaete family tree. It also concluded that the classification of polychaetes into Scolecida, Canalipalpata and Aciculata was useless, as the members of these alleged groups were scattered all over the family tree derived from comparing the 81 taxa. In addition, it also placed sipunculans, generally regarded at the time as a separate phylum, on another branch of the polychaete tree, and concluded that leeches were a sub-group of oligochaetes rather than their sister-group among the clitellates. Rouse accepted the analyses based on molecular phylogenetics, and their main conclusions are now the scientific consensus, although the details of the annelid family tree remain uncertain. Question: Who compared annelid genes in 2007?
Example Output:
Torsten Struck and colleagues
