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

Ex Input:
Passage: Several states have never had capital punishment, the first being Michigan, which abolished it shortly after entering the Union. (However, the United States government executed Tony Chebatoris at the Federal Correctional Institution in Milan, Michigan in 1938.) Article 4, Section 46 of Michigan's fourth Constitution (ratified in 1963; effective in 1964) prohibits any law providing for the penalty of death. Attempts to change the provision have failed. In 2004, a constitutional amendment proposed to allow capital punishment in some circumstances failed to make it on the November ballot after a resolution failed in the legislature and a public initiative failed to gather enough signatures.

Ex Output:
What happened in 1935?

Ex Input:
Passage: The Jenkins Orphanage was established in 1891 by the Rev. Daniel J. Jenkins in Charleston. The orphanage accepted donations of musical instruments and Rev. Jenkins hired local Charleston musicians and Avery Institute Graduates to tutor the boys in music. As a result, Charleston musicians became proficient on a variety of instruments and were able to read music expertly. These traits set Jenkins musicians apart and helped land some of them positions in big bands with Duke Ellington and Count Basie. William "Cat" Anderson, Jabbo Smith, and Freddie Green are but a few of the alumni from the Jenkins Orphanage band who became professional musicians in some of the best bands of the day. Orphanages around the country began to develop brass bands in the wake of the Jenkins Orphanage Band's success. At the Colored Waif's Home Brass Band in New Orleans, for example, a young trumpeter named Louis Armstrong first began to draw attention.

Ex Output:
What year was the Jenkins Orphanage closed?

Ex Input:
Passage: Land-based steam engines could exhaust much of their steam, as feed water was usually readily available. Prior to and during World War I, the expansion engine dominated marine applications where high vessel speed was not essential. It was however superseded by the British invention steam turbine where speed was required, for instance in warships, such as the dreadnought battleships, and ocean liners. HMS Dreadnought of 1905 was the first major warship to replace the proven technology of the reciprocating engine with the then-novel steam turbine.[citation needed]

Ex Output:
The frequent availability of what substance allowed land-based steam engines to exhaust a great deal of battleships?
