instruction:
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.
question:
Passage: Most biological entities that are more complex than a virus sometimes or always carry additional genetic material besides that which resides in their chromosomes. In some contexts, such as sequencing the genome of a pathogenic microbe, "genome" is meant to include information stored on this auxiliary material, which is carried in plasmids. In such circumstances then, "genome" describes all of the genes and information on non-coding DNA that have the potential to be present.
answer:
What do viruses always carry within their structure?

question:
Passage: Tajikistan means the "Land of the Tajiks". The suffix "-stan" (Persian: -stan) is Persian for "place of" or "country" and Tajik is, most likely, the name of a pre-Islamic (before the seventh century A.D.) tribe. According to the Library of Congress's 1997 Country Study of Tajikistan, it is difficult to definitively state the origins of the word "Tajik" because the term is "embroiled in twentieth-century political disputes about whether Turkic or Iranian peoples were the original inhabitants of Central Asia."
answer:
Which country's name means "Land of the Talks"?

question:
Passage: The earliest known inscriptions in Sanskrit date to the first century BCE.[citation needed] They are in the Brahmi script, which was originally used for Prakrit, not Sanskrit. It has been described as a paradox that the first evidence of written Sanskrit occurs centuries later than that of the Prakrit languages which are its linguistic descendants. In northern India, there are Brahmi inscriptions dating from the third century BCE onwards, the oldest appearing on the famous Prakrit pillar inscriptions of king Ashoka. The earliest South Indian inscriptions in Tamil Brahmi, written in early Tamil, belong to the same period. When Sanskrit was written down, it was first used for texts of an administrative, literary or scientific nature. The sacred texts were preserved orally, and were set down in writing "reluctantly" (according to one commentator), and at a comparatively late date.
answer:
When were the latest inscriptions in Sanskrit known to exist?
