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: One way to divide hunter-gatherer groups is by their return systems. James Woodburn uses the categories "immediate return" hunter-gatherers for egalitarian and "delayed return" for nonegalitarian. Immediate return foragers consume their food within a day or two after they procure it. Delayed return foragers store the surplus food (Kelly, 31).
Example Output: What is the only way to divide hunter-gatherer groups?

Example Input: Passage: Once at Golgotha, Jesus was offered wine mixed with gall to drink. Matthew's and Mark's Gospels record that he refused this. He was then crucified and hung between two convicted thieves. According to some translations from the original Greek, the thieves may have been bandits or Jewish rebels. According to Mark's Gospel, he endured the torment of crucifixion for some six hours from the third hour, at approximately 9 am, until his death at the ninth hour, corresponding to about 3 pm. The soldiers affixed a sign above his head stating "Jesus of Nazareth, King of the Jews" in three languages, divided his garments and cast lots for his seamless robe. The Roman soldiers did not break Jesus' legs, as they did to the other two men crucified (breaking the legs hastened the crucifixion process), as Jesus was dead already. Each gospel has its own account of Jesus' last words, seven statements altogether. In the Synoptic Gospels, various supernatural events accompany the crucifixion, including darkness, an earthquake, and (in Matthew) the resurrection of saints. Following Jesus' death, his body was removed from the cross by Joseph of Arimathea and buried in a rock-hewn tomb, with Nicodemus assisting.
Example Output: What was offered to the two thieves to drink?

Example Input: Passage: Newly electrified lines often show a "sparks effect", whereby electrification in passenger rail systems leads to significant jumps in patronage / revenue. The reasons may include electric trains being seen as more modern and attractive to ride, faster and smoother service, and the fact that electrification often goes hand in hand with a general infrastructure and rolling stock overhaul / replacement, which leads to better service quality (in a way that theoretically could also be achieved by doing similar upgrades yet without electrification). Whatever the causes of the sparks effect, it is well established for numerous routes that have electrified over decades.
Example Output:
Electrification in passenger rail systems leads to insignificant jumps in what?
