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: While its fellow Canadian broadcasters converted most of their transmitters to digital by the Canadian digital television transition deadline of August 31, 2011, CBC converted only about half of the analogue transmitters in mandatory areas to digital (15 of 28 markets with CBC Television stations, and 14 of 28 markets with Télévision de Radio-Canada stations). Due to financial difficulties reported by the corporation, the corporation published digital transition plans for none of its analogue retransmitters in mandatory markets to be converted to digital by the deadline. Under this plan, communities that receive analogue signals by rebroadcast transmitters in mandatory markets would lose their over-the-air signals as of the deadline. Rebroadcast transmitters account for 23 of the 48 CBC and Radio-Canada transmitters in mandatory markets. Mandatory markets losing both CBC and Radio-Canada over-the-air signals include London, Ontario (metropolitan area population 457,000) and Saskatoon, Saskatchewan (metro area population 257,000). In both of those markets, the corporation's television transmitters are the only ones that were not planned to be converted to digital by the deadline.

Ex Output:
The CBC petitioned to change what original deadline for converting transmission from digital to analog?

Passage: For air dielectric capacitors the breakdown field strength is of the order 2 to 5 MV/m; for mica the breakdown is 100 to 300 MV/m; for oil, 15 to 25 MV/m; it can be much less when other materials are used for the dielectric. The dielectric is used in very thin layers and so absolute breakdown voltage of capacitors is limited. Typical ratings for capacitors used for general electronics applications range from a few volts to 1 kV. As the voltage increases, the dielectric must be thicker, making high-voltage capacitors larger per capacitance than those rated for lower voltages. The breakdown voltage is critically affected by factors such as the geometry of the capacitor conductive parts; sharp edges or points increase the electric field strength at that point and can lead to a local breakdown. Once this starts to happen, the breakdown quickly tracks through the dielectric until it reaches the opposite plate, leaving carbon behind and causing a short (or relatively low resistance) circuit. The results can be explosive as the short in the capacitor draws current from the surrounding circuitry and dissipates the energy.

Ex Output:
What order is the breakdown field weakness for air dielectric capacitors of?

Passage: Between April 1877 and February 1878, she threatened five times to abdicate while pressuring Disraeli to act against Russia during the Russo-Turkish War, but her threats had no impact on the events or their conclusion with the Congress of Berlin. Disraeli's expansionist foreign policy, which Victoria endorsed, led to conflicts such as the Anglo-Zulu War and the Second Anglo-Afghan War. "If we are to maintain our position as a first-rate Power", she wrote, "we must ... be Prepared for attacks and wars, somewhere or other, CONTINUALLY." Victoria saw the expansion of the British Empire as civilising and benign, protecting native peoples from more aggressive powers or cruel rulers: "It is not in our custom to annexe countries", she said, "unless we are obliged & forced to do so." To Victoria's dismay, Disraeli lost the 1880 general election, and Gladstone returned as prime minister. When Disraeli died the following year, she was blinded by "fast falling tears", and erected a memorial tablet "placed by his grateful Sovereign and Friend, Victoria R.I."

Ex Output:

Who did Victoria try to convince Disraeli to act against during the Russo-Turkish war?
