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.

Ex Input:
Passage: Thermodynamics divides energy transformation into two kinds: reversible processes and irreversible processes. An irreversible process is one in which energy is dissipated (spread) into empty energy states available in a volume, from which it cannot be recovered into more concentrated forms (fewer quantum states), without degradation of even more energy. A reversible process is one in which this sort of dissipation does not happen. For example, conversion of energy from one type of potential field to another, is reversible, as in the pendulum system described above. In processes where heat is generated, quantum states of lower energy, present as possible excitations in fields between atoms, act as a reservoir for part of the energy, from which it cannot be recovered, in order to be converted with 100% efficiency into other forms of energy. In this case, the energy must partly stay as heat, and cannot be completely recovered as usable energy, except at the price of an increase in some other kind of heat-like increase in disorder in quantum states, in the universe (such as an expansion of matter, or a randomisation in a crystal).

Ex Output:
Thermodynamics multiplies energy information into what two kinds?


Ex Input:
Passage: As the Grand Duchy of Finland was part of the Russian Empire from 1809 to 1918, a number of Russian speakers have remained in Finland. There are 33,400 Russian-speaking Finns, amounting to 0.6% of the population. Five thousand (0.1%) of them are late 19th century and 20th century immigrants or their descendants, and the remaining majority are recent immigrants who moved there in the 1990s and later.[citation needed] Russian is spoken by 1.4% of the population of Finland according to a 2014 estimate from the World Factbook.

Ex Output:
When did immigrants form the Russian Empire?


Ex Input:
Passage: Johnson's impeachment was perceived to have done great damage to the presidency, which came to be almost subordinate to Congress. Some believed that the president would become a mere figurehead, with the Speaker of the House of Representatives becoming a de facto Prime Minister. Grover Cleveland, the first Democratic President following Johnson, attempted to restore the power of his office. During his first term, he vetoed over four hundred bills—twice as many bills as his twenty-one predecessors combined. He also began to suspend bureaucrats who were appointed as a result of the patronage system, replacing them with more "deserving" individuals. The Senate, however, refused to confirm many new nominations, instead demanding that Cleveland turn over the confidential records relating to the suspensions. Cleveland steadfastly refused, asserting, "These suspensions are my executive acts ... I am not responsible to the Senate, and I am unwilling to submit my actions to them for judgment." Cleveland's popular support forced the Senate to back down and confirm the nominees. Furthermore, Congress finally repealed the controversial Tenure of Office Act that had been passed during the Johnson Administration. Overall, this meant that Cleveland's Administration marked the end of presidential subordination.

Ex Output:

What did Cleveland's impeachment do to the presidency?
