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.

Input: Consider Input: Passage: The time and space hierarchy theorems form the basis for most separation results of complexity classes. For instance, the time hierarchy theorem tells us that P is strictly contained in EXPTIME, and the space hierarchy theorem tells us that L is strictly contained in PSPACE.

Output: What does not form the basis for most separation results of complexity classes?


Input: Consider Input: Passage: Different religious traditions assign differing (though often similar) attributes and characteristics to God, including expansive powers and abilities, psychological characteristics, gender characteristics, and preferred nomenclature. The assignment of these attributes often differs according to the conceptions of God in the culture from which they arise. For example, attributes of God in Christianity, attributes of God in Islam, and the Thirteen Attributes of Mercy in Judaism share certain similarities arising from their common roots.

Output: What beliefs have similar psychological characteristics?


Input: Consider Input: Passage: The Arsacid Kingdom of Armenia, itself a branch of the Arsacid dynasty of Parthia, was the first state to adopt Christianity as its religion (it had formerly been adherent to Armenian paganism, which was influenced by Zoroastrianism, while later on adopting a few elements regarding identification of its pantheon with Greco-Roman deities). in the early years of the 4th century, likely AD 301, partly in defiance of the Sassanids it seems. In the late Parthian period, Armenia was a predominantly Zoroastrian-adhering land, but by the Christianisation, previously predominant Zoroastrianism and paganism in Armenia gradually declined. Later on, in order to further strengthen Armenian national identity, Mesrop Mashtots invented the Armenian alphabet, in 405 AD. This event ushered the Golden Age of Armenia, during which many foreign books and manuscripts were translated to Armenian by Mesrop's pupils. Armenia lost its sovereignty again in 428 AD to the rivalling Byzantine and Sassanid Persian empires, until the Muslim conquest of Persia overran also the regions in which Armenians lived.


Output: What did the Arsacid Kingdom invent in 405 AD?
