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.

[EX Q]: Passage: Because of their long life, fast switching times, and their ability to be seen in broad daylight due to their high output and focus, LEDs have been used in brake lights for cars' high-mounted brake lights, trucks, and buses, and in turn signals for some time, but many vehicles now use LEDs for their rear light clusters. The use in brakes improves safety, due to a great reduction in the time needed to light fully, or faster rise time, up to 0.5 second faster[citation needed] than an incandescent bulb. This gives drivers behind more time to react. In a dual intensity circuit (rear markers and brakes) if the LEDs are not pulsed at a fast enough frequency, they can create a phantom array, where ghost images of the LED will appear if the eyes quickly scan across the array. White LED headlamps are starting to be used. Using LEDs has styling advantages because LEDs can form much thinner lights than incandescent lamps with parabolic reflectors.
[EX A]: Why are non-LED lights sought after for various applications?

[EX Q]: Passage: Most of the Alsatian population is Roman Catholic, but, largely because of the region's German heritage, a significant Protestant community also exists: today, the EPCAAL (a Lutheran church) is France's second largest Protestant church, also forming an administrative union (UEPAL) with the much smaller Calvinist EPRAL. Unlike the rest of France, the Local law in Alsace-Moselle still provides for to the Napoleonic Concordat of 1801 and the organic articles, which provides public subsidies to the Roman Catholic, Lutheran, and Calvinist churches, as well as to Jewish synagogues; religion classes in one of these faiths is compulsory in public schools. This divergence in policy from the French majority is due to the region having been part of Imperial Germany when the 1905 law separating the French church and state was instituted (for a more comprehensive history, see: Alsace-Lorraine). Controversy erupts periodically on the appropriateness of this legal disposition, as well as on the exclusion of other religions from this arrangement.
[EX A]: What is the name of the second largest Roman Catholic church?

[EX Q]: Passage: Cetaceans were historically abundant around the island as commercial hunts on the island was operating until 1956. Today, numbers of larger whales have disappeared, but even today many species such humpback whale, minke whale, sei whale, and dolphins can be observed close to shores, and scientific surveys have been conducted regularly. Southern right whales were once regular migrants to the Norfolk hence naming the island as the "Middle ground" by whalers, but had been severely depleted by historical hunts, and further by illegal Soviet and Japan whaling, resulting in none of very few, if remnants still live, right whales in these regions along with Lord Howe Island.
[EX A]:
What was never abundant in the waters around Norfolk Island?
