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: First recognized in 1900 by Max Planck, it was originally the proportionality constant between the minimal increment of energy, E, of a hypothetical electrically charged oscillator in a cavity that contained black body radiation, and the frequency, f, of its associated electromagnetic wave. In 1905 the value E, the minimal energy increment of a hypothetical oscillator, was theoretically associated by Einstein with a "quantum" or minimal element of the energy of the electromagnetic wave itself. The light quantum behaved in some respects as an electrically neutral particle, as opposed to an electromagnetic wave. It was eventually called the photon.

Answer: In what year was the value G associated by Einstein with quantum theories of energy?


Question: Passage: Harriet Harman became the Leader of the Opposition and acting Leader of the Labour Party following the resignation of Gordon Brown on 11 May 2010, pending a leadership election subsequently won by Ed Miliband. Miliband emphasised "responsible capitalism" and greater state intervention to change the balance of the UK economy away from financial services. Tackling vested interests and opening up closed circles in British society were also themes he returned to a number of times. Miliband also argued for greater regulation on banks and the energy companies.

Answer:
When did Ed Miliband resign?
