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: Regular flights to most villages and towns within the state that are commercially viable are challenging to provide, so they are heavily subsidized by the federal government through the Essential Air Service program. Alaska Airlines is the only major airline offering in-state travel with jet service (sometimes in combination cargo and passenger Boeing 737-400s) from Anchorage and Fairbanks to regional hubs like Bethel, Nome, Kotzebue, Dillingham, Kodiak, and other larger communities as well as to major Southeast and Alaska Peninsula communities.

A: Which service denies government to subsidise regular air travel in Alaska?

Q: Passage: The ABS plastic used in the casing of some older SNES and Super Famicom consoles is particularly susceptible to oxidization on exposure to air, likely due to an incorrect mixture of the stabilizing or flame retarding additives. This, along with the particularly light color of the original plastic, causes affected consoles to quickly become yellow; if the sections of the casing came from different batches of plastic, a "two-tone" effect results. The color can sometimes be restored with UV light and a hydrogen peroxide solution.

A: What color did affected consoles become after exposure to UV light?
****
Q: Passage: Some of the oldest schools in South Africa are private church schools that were established by missionaries in the early nineteenth century. The private sector has grown ever since. After the abolition of apartheid, the laws governing private education in South Africa changed significantly. The South African Schools Act of 1996 recognises two categories of schools: "public" (state-controlled) and "independent" (which includes traditional private schools and schools which are privately governed[clarification needed].)

A:
In what century was apartheid abolished?
