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: Usually, a federation is formed at two levels: the central government and the regions (states, provinces, territories), and little to nothing is said about second or third level administrative political entities. Brazil is an exception, because the 1988 Constitution included the municipalities as autonomous political entities making the federation tripartite, encompassing the Union, the States, and the municipalities. Each state is divided into municipalities (municípios) with their own legislative council (câmara de vereadores) and a mayor (prefeito), which are partly autonomous from both Federal and State Government. Each municipality has a "little constitution", called "organic law" (lei orgânica). Mexico is an intermediate case, in that municipalities are granted full-autonomy by the federal constitution and their existence as autonomous entities (municipio libre, "free municipality") is established by the federal government and cannot be revoked by the states' constitutions. Moreover, the federal constitution determines which powers and competencies belong exclusively to the municipalities and not to the constituent states. However, municipalities do not have an elected legislative assembly.

Ex Output:
When is a federation dissolved?

Passage: Nontrinitarians, such as Unitarians, Christadelphians and Jehovah's Witnesses also acknowledge Mary as the biological mother of Jesus Christ, but do not recognise Marian titles such as "Mother of God" as these groups generally reject Christ's divinity. Since Nontrinitarian churches are typically also mortalist, the issue of praying to Mary, whom they would consider "asleep", awaiting resurrection, does not arise. Emanuel Swedenborg says God as he is in himself could not directly approach evil spirits to redeem those spirits without destroying them (Exodus 33:20, John 1:18), so God impregnated Mary, who gave Jesus Christ access to the evil heredity of the human race, which he could approach, redeem and save.

Ex Output:

Why type of churches did Emanuel Swedenborg visit?
