This task is about reading the given passage and construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) its answer is a continuous text span from the paragraph. Avoid creating questions that (i) can be answered correctly without actually understanding the paragraph and (ii) uses same words or phrases given in the passage.

Example Input: In cpDNA, there are several A → G deamination gradients. DNA becomes susceptible to deamination events when it is single stranded. When replication forks form, the strand not being copied is single stranded, and thus at risk for A → G deamination. Therefore, gradients in deamination indicate that replication forks were most likely present and the direction that they initially opened (the highest gradient is most likely nearest the start site because it was single stranded for the longest amount of time). This mechanism is still the leading theory today; however, a second theory suggests that most cpDNA is actually linear and replicates through homologous recombination. It further contends that only a minority of the genetic material is kept in circular chromosomes while the rest is in branched, linear, or other complex structures.
Example Output: What kind of gradients does cpDNA have?

Example Input: General Dong Zhuo (d. 192 AD) found the young emperor and his brother wandering in the countryside. He escorted them safely back to the capital and was made Minister of Works, taking control of Luoyang and forcing Yuan Shao to flee. After Dong Zhuo demoted Emperor Shao and promoted his brother Liu Xie as Emperor Xian, Yuan Shao led a coalition of former officials and officers against Dong, who burned Luoyang to the ground and resettled the court at Chang'an in May 191 AD. Dong Zhuo later poisoned Emperor Shao.
Example Output: How was Luoyang destroyed?

Example Input: The Soviet request to join NATO arose in the aftermath of the Berlin Conference of January–February 1954. Soviet foreign minister Molotov made proposals to have Germany reunified and elections for a pan-German government, under conditions of withdrawal of the four powers armies and German neutrality, but all were refused by the other foreign ministers, Dulles (USA), Eden (UK) and Bidault (France). Proposals for the reunification of Germany were nothing new: earlier on 20 March 1952, talks about a German reunification, initiated by the socalled 'Stalin Note', ended after the United Kingdom, France, and the United States insisted that a unified Germany should not be neutral and should be free to join the European Defence Community and rearm. James Dunn (USA), who met in Paris with Eden, Adenauer and Robert Schuman (France), affirmed that "the object should be to avoid discussion with the Russians and to press on the European Defense Community". According to John Gaddis "there was little inclination in Western capitals to explore this offer" from USSR. While historian Rolf Steininger asserts that Adenauer's conviction that “neutralization means sovietization” was the main factor in the rejection of the soviet proposals, Adenauer also feared that unification might have resulted in the end of the CDU's dominance in the Bundestag.
Example Output:
Who was the Soviet minister who proposed German reunification?
