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.

Example Input: Passage: The control of associated biodiversity is one of the great agricultural challenges that farmers face. On monoculture farms, the approach is generally to eradicate associated diversity using a suite of biologically destructive pesticides, mechanized tools and transgenic engineering techniques, then to rotate crops. Although some polyculture farmers use the same techniques, they also employ integrated pest management strategies as well as strategies that are more labor-intensive, but generally less dependent on capital, biotechnology and energy.
Example Output: What is one of the great polyculture challenges that farmers face?

Example Input: Passage: To compete with the popular Family Computer in Japan, NEC Home Electronics launched the PC Engine in 1987, and Sega Enterprises followed suit with the Mega Drive in 1988. The two platforms were later launched in North America in 1989 as the TurboGrafx-16 and the Genesis respectively. Both systems were built on 16-bit architectures and offered improved graphics and sound over the 8-bit NES. However, it took several years for Sega's system to become successful. Nintendo executives were in no rush to design a new system, but they reconsidered when they began to see their dominance in the market slipping.
Example Output: What did SEGA release in 1987?

Example Input: Passage: After the revocation of the Edict of Nantes, the Dutch Republic received the largest group of Huguenot refugees, an estimated total of 75,000 to 100,000 people. Amongst them were 200 clergy. Many came from the region of the Cévennes, for instance, the village of Fraissinet-de-Lozère. This was a huge influx as the entire population of the Dutch Republic amounted to ca. 2 million at that time. Around 1700, it is estimated that nearly 25% of the Amsterdam population was Huguenot.[citation needed] In 1705, Amsterdam and the area of West Frisia were the first areas to provide full citizens rights to Huguenot immigrants, followed by the Dutch Republic in 1715. Huguenots intermarried with Dutch from the outset.
Example Output:
How many Huguenots lived in West Frisia in 1705?
