PROBLEM: Question: Who was in charge of the country Ottwalt finally ended up in? Passage:In 1933, Ottwalt and his wife, Waltraut, left Germany and went into exile in Denmark, then, by way of Czechoslovakia, ended up in the Soviet Union. Living in Moscow, Ottwalt wrote for the German exile magazine Internationale Literatur (published by Johannes R. Becher) and was an editor at Vegaar Bibliothek. He also wrote for the Deutsche Zentral Zeitung. In 1936, he and his wife were ensnared in the Stalinist purges and arrested by the Soviet secret police, the NKVD. He was charged with suspicion of espionage, sentenced to forced labor and deported to a gulag near Archangelsk. His wife was sentenced to forced labor in Kotlas. She was deported back to Germany in January 1941 and didn't learn about his death until January 1958, when the Soviet Red Cross informed her that her husband had died on 24 August 1943.

PROBLEM: Question: Of the provinces populated by founders of the Qing dynasty, which one has a larger population? Passage:The Qing dynasty was founded not by Han Chinese, who form the majority of the Chinese population, but by a sedentary farming people known as the Jurchen, a Tungusic people who lived around the region now comprising the Chinese provinces of Jilin and Heilongjiang. Although the Ming dynasty held control over Manchuria since the late 1380s, Ming political existence in the region waned considerably after the death of the Yongle Emperor. What was to become the Manchu state was founded by Nurhaci, the chieftain of a minor Jurchen tribe in Jianzhou in the early 17th century. Originally a vassal of the Ming emperors, Nurhaci started to take actual control of most of Manchuria over the next several decades. In 1616, he declared himself the "Bright Khan" of the Later Jin state. Two years later he announced the "Seven Grievances" and openly renounced the sovereignty of Ming overlordship to complete the unification of those Jurchen tribes still allied with the Ming emperor. After a series of successful battles against both the Ming and various tribes in Outer Manchuria, he and his son Hong Taiji eventually controlled the whole of Manchuria. Soon after the establishment of the Qing dynasty, the territory of today's Primorsky Kray was made part of the Government-general of Jilin, and along with the lower Amur area was controlled from Ninguta (a garrison town south of today's Mudanjiang).

PROBLEM: Question: Which of the episodes featuring Malohkek aired first? Passage:Chibnall suggested including a "bonkers" gang of characters picked from around time and space. He felt that Doctor Who could have "collisions of characters that no other show in the world can do", and that it was about finding a "disparate" group of characters who would "bounce" off each other. Nefertiti's decision not to return to her own time fits in with the historical record, as the date and cause of her death are unknown. Chibnall asked to introduce Rory's father, as Amy and Rory would be leaving in four episodes and Rory's family life had not been explored yet. Mark Williams who played Rory's father previously appeared in the Fifth Doctor audio adventure The Eternal Summer. Rupert Graves, who played an Edwardian hunter in this episode, previously worked with Moffat on the BBC series Sherlock. David Bradley's character, Solomon, was modelled on a "well-known nightclub owner with long hair". Chibnall described him as "half businessman, half Somali pirate". Bradley and Williams had previously worked together on the Harry Potter film franchise. Bradley was later cast as the First Doctor William Hartnell for the 50th anniversary documentary drama An Adventure in Space and Time. Comedy duo Mitchell and Webb provided the voices of Solomon's two robots; executive producer Caroline Skinner called the casting choice "perfect". Richard Hope, who played the Silurian Bleytal, previously appeared as Malohkeh in the episodes "The Hungry Earth", "Cold Blood" and "The Wedding of River Song".

SOLUTION:
Richard Hope, who played the Silurian Bleytal, previously appeared as Malohkeh in the episodes "The Hungry Earth", "Cold Blood" and "The Wedding of River Song"
