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: Planetary geologists have measured different abundances of oxygen isotopes in samples from the Earth, the Moon, Mars, and meteorites, but were long unable to obtain reference values for the isotope ratios in the Sun, believed to be the same as those of the primordial solar nebula. Analysis of a silicon wafer exposed to the solar wind in space and returned by the crashed Genesis spacecraft has shown that the Sun has a higher proportion of oxygen-16 than does the Earth. The measurement implies that an unknown process depleted oxygen-16 from the Sun's disk of protoplanetary material prior to the coalescence of dust grains that formed the Earth.

Ex Output:
Where have Genesis geologists measured oxygen isotopes?

Passage: English Dominican mysticism in the late medieval period differed from European strands of it in that, whereas European Dominican mysticism tended to concentrate on ecstatic experiences of union with the divine, English Dominican mysticism's ultimate focus was on a crucial dynamic in one's personal relationship with God. This was an essential moral imitation of the Savior as an ideal for religious change, and as the means for reformation of humanity's nature as an image of divinity. This type of mysticism carried with it four elements. First, spiritually it emulated the moral essence of Christ's life. Second, there was a connection linking moral emulation of Christ's life and humanity's disposition as images of the divine. Third, English Dominican mysticism focused on an embodied spirituality with a structured love of fellow men at its center. Finally, the supreme aspiration of this mysticism was either an ethical or an actual union with God.

Ex Output:
What did European mysticism and English mysticism both concentrate on?

Passage: Confer With the White House. If his or her party controls the White House, the minority leader confers regularly with the President and his aides about issues before Congress, the Administration's agenda, and political events generally. Strategically, the role of the minority leader will vary depending on whether the President is of the same party or the other party. In general, minority leaders will often work to advance the goals and aspirations of their party's President in Congress. When Robert Michel, R-IL, was minority leader (1981–1995), he typically functioned as the "point man" for Republican presidents. President Ronald Reagan's 1981 policy successes in the Democratic controlled House was due in no small measure to Minority Leader Michel's effectiveness in wooing so-called "Reagan Democrats" to support, for instance, the Administration's landmark budget reconciliation bill. There are occasions, of course, when minority leaders will fault the legislative initiatives of their President. On an administration proposal that could adversely affect his district, Michel stated that he might "abdicate my leadership role [on this issue] since I can't harmonize my own views with the administration's." Minority Leader Gephardt, as another example, has publicly opposed a number of President Clinton's legislative initiatives from "fast track" trade authority to various budget issues.

Ex Output:

When did Gephardt serve as Minority Leader?
