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.

Passage: Second, Democrats have always elevated their minority floor leader to the speakership upon reclaiming majority status. Republicans have not always followed this leadership succession pattern. In 1919, for instance, Republicans bypassed James R. Mann, R-IL, who had been minority leader for eight years, and elected Frederick Gillett, R-MA, to be Speaker. Mann "had angered many Republicans by objecting to their private bills on the floor;" also he was a protégé of autocratic Speaker Joseph Cannon, R-IL (1903–1911), and many Members "suspected that he would try to re-centralize power in his hands if elected Speaker." More recently, although Robert H. Michel was the Minority Leader in 1994 when the Republicans regained control of the House in the 1994 midterm elections, he had already announced his retirement and had little or no involvement in the campaign, including the Contract with America which was unveiled six weeks before voting day.
What have Republicans always elevated their minority floor leader to when obtaining majority status?

Passage: European colonialism in the Sahara began in the 19th century. France conquered the regency of Algiers from the Ottomans in 1830, and French rule spread south from Algeria and eastwards from Senegal into the upper Niger to include present-day Algeria, Chad, Mali then French Sudan including Timbuktu, Mauritania, Morocco (1912), Niger, and Tunisia (1881). By the beginning of the 20th century, the trans-Saharan trade had clearly declined because goods were moved through more modern and efficient means, such as airplanes, rather than across the desert.
When did the Ottomans conquer France?

Passage: After the war, Feynman declined an offer from the Institute for Advanced Study in Princeton, New Jersey, despite the presence there of such distinguished faculty members as Albert Einstein, Kurt Gödel and John von Neumann. Feynman followed Hans Bethe, instead, to Cornell University, where Feynman taught theoretical physics from 1945 to 1950. During a temporary depression following the destruction of Hiroshima by the bomb produced by the Manhattan Project, he focused on complex physics problems, not for utility, but for self-satisfaction. One of these was analyzing the physics of a twirling, nutating dish as it is moving through the air. His work during this period, which used equations of rotation to express various spinning speeds, proved important to his Nobel Prize–winning work, yet because he felt burned out and had turned his attention to less immediately practical problems, he was surprised by the offers of professorships from other renowned universities.

Which college did Feynman always have a job in?
