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.

[Q]: Passage: Uranium carbides and uranium nitrides are both relatively inert semimetallic compounds that are minimally soluble in acids, react with water, and can ignite in air to form U
3O
8. Carbides of uranium include uranium monocarbide (UC), uranium dicarbide (UC
2), and diuranium tricarbide (U
2C
3). Both UC and UC
2 are formed by adding carbon to molten uranium or by exposing the metal to carbon monoxide at high temperatures. Stable below 1800 C, U
2C
3 is prepared by subjecting a heated mixture of UC and UC
2 to mechanical stress. Uranium nitrides obtained by direct exposure of the metal to nitrogen include uranium mononitride (UN), uranium dinitride (UN
2), and diuranium trinitride (U
2N
3).
[A]: Along with uranium monocarbide and uranium dicarbide, what is a unnotable carbide of uranium?

[Q]: Passage: Although anthropologists worldwide refer to Tylor's definition of culture, in the 20th century "culture" emerged as the central and unifying concept of American anthropology, where it most commonly refers to the universal human capacity to classify and encode human experiences symbolically, and to communicate symbolically encoded experiences socially.[citation needed] American anthropology is organized into four fields, each of which plays an important role in research on culture: biological anthropology, linguistic anthropology, cultural anthropology, and archaeology.
[A]: Who's definition of culture did anthropologists reject?

[Q]: Passage: Relaxed zoning rules and special parking privileges for churches, the tax-free status of church property, the fact that Christmas is a federal holiday, etc., have also been questioned, but have been considered examples of the governmental prerogative in deciding practical and beneficial arrangements for the society. The national motto "In God We Trust" has been challenged as a violation, but the Supreme Court has ruled that ceremonial deism is not religious in nature. A circuit court ruling affirmed Ohio's right to use as its motto a passage from the Bible, "With God, all things are possible", because it displayed no preference for a particular religion.
[A]:
Why have perks like relaxed zoning rules and special parking privileges been disallowed for churches?
