This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.

Question: Passage: During the early 20th century, northerners were attracted to the city, and Miami prospered during the 1920s with an increase in population and infrastructure. The legacy of Jim Crow was embedded in these developments. Miami's chief of police, H. Leslie Quigg, did not hide the fact that he, like many other white Miami police officers, was a member of the Ku Klux Klan. Unsurprisingly, these officers enforced social codes far beyond the written law. Quigg, for example, "personally and publicly beat a colored bellboy to death for speaking directly to a white woman."

Answer: Who was a unnotable chief of the Miami police?


Question: Passage: Labour went on to win the 1950 general election, but with a much reduced majority of five seats. Soon afterwards, defence became a divisive issue within the party, especially defence spending (which reached a peak of 14% of GDP in 1951 during the Korean War), straining public finances and forcing savings elsewhere. The Chancellor of the Exchequer, Hugh Gaitskell, introduced charges for NHS dentures and spectacles, causing Bevan, along with Harold Wilson (then President of the Board of Trade), to resign over the dilution of the principle of free treatment on which the NHS had been established.

Answer: In what year did Labour lose the general election?


Question: Passage: In intelligent mammals, such as primates, the cerebrum is larger relative to the rest of the brain. Intelligence itself is not easy to define, but indications of intelligence include the ability to learn, matched with behavioral flexibility. Rats, for example, are considered to be highly intelligent, as they can learn and perform new tasks, an ability that may be important when they first colonize a fresh habitat. In some mammals, food gathering appears to be related to intelligence: a deer feeding on plants has a brain smaller than a cat, which must think to outwit its prey.

Answer:
What part of the brain is larger in rats compared to the rest of the brain?
