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.

Passage: In early 12th-century al-Andalus, the Arabian philosopher, Ibn Tufail (Abubacer), wrote discussions on materialism in his philosophical novel, Hayy ibn Yaqdhan (Philosophus Autodidactus), while vaguely foreshadowing the idea of a historical materialism.

Passage: Vacuum is space void of matter. The word stems from the Latin adjective vacuus for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a perfect vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is lower than atmospheric pressure. The Latin term in vacuo is used to describe an object as being in what would otherwise be a vacuum.
What Latin adjective does atmospheric pressure come from?

Passage: Following the breakup of the Russian Empire in the aftermath of World War I for a brief period, from 1918 to 1920, Armenia was an independent republic. In late 1920, the communists came to power following an invasion of Armenia by the Red Army, and in 1922, Armenia became part of the Transcaucasian SFSR of the Soviet Union, later forming the Armenian Soviet Socialist Republic (1936 to September 21, 1991). In 1991, Armenia declared independence from the USSR and established the second Republic of Armenia.

When was the Red Army part of an independent republic after the Russian Empire breakup?
