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: Laemmle, Jr. created a niche for the studio, beginning a series of horror films which extended into the 1940s, affectionately dubbed Universal Horror. Among them are Frankenstein (1931), Dracula ( also in 1931), The Mummy (1932) and The Invisible Man (1933). Other Laemmle productions of this period include Imitation of Life (1934) and My Man Godfrey (1936).

[Q]: Passage: Several species of pines characteristic of the Appalachians are eastern white pine (Pinus strobus ), Virginia pine (Pinus virginiana), pitch pine (Pinus rigida ), Table Mountain pine (Pinus pungens) and shortleaf pine (Pinus echinata). Red pine (Pinus resinosa) is a boreal species that forms a few high elevation outliers as far south as West Virginia. All of these species except white pine tend to occupy sandy, rocky, poor soil sites, which are mostly acidic in character. White pine, a large species valued for its timber, tends to do best in rich, moist soil, either acidic or alkaline in character. Pitch pine is also at home in acidic, boggy soil, and Table Mountain pine may occasionally be found in this habitat as well. Shortleaf pine is generally found in warmer habitats and at lower elevations than the other species. All the species listed do best in open or lightly shaded habitats, although white pine also thrives in shady coves, valleys, and on floodplains.
[A]: What type of species is the pitch pine?


[Q]: Passage: The statement that Joseph "knew her not till she brought forth her first born son" (Matthew 1:25 DouayRheims) has been debated among scholars, with some saying that she did not remain a virgin and some saying that she was a perpetual virgin. Other scholars contend that the Greek word heos (i.e., until) denotes a state up to a point, but does not mean that the state ended after that point, and that Matthew 1:25 does not confirm or deny the virginity of Mary after the birth of Jesus. According to Biblical scholar Bart Ehrman the Hebrew word almah, meaning young woman of childbearing age, was translated into Greek as parthenos, which only means virgin, in Isaiah 7:14, which is commonly believed by Christians to be the prophecy of the Virgin Mary referred to in Matthew 1:23. While Matthew and Luke give differing versions of the virgin birth, John quotes the uninitiated Philip and the disbelieving Jews gathered at Galilee referring to Joseph as Jesus's father.
[A]:
Who knew Mary before she brought forth her first born son?
