instruction:
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.
question:
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.
answer:
What was offered to the two thieves to drink?


question:
Passage: Glass has the ability to refract, reflect, and transmit light following geometrical optics, without scattering it. It is used in the manufacture of lenses and windows. Common glass has a refraction index around 1.5. This may be modified by adding low-density materials such as boron, which lowers the index of refraction (see crown glass), or increased (to as much as 1.8) with high-density materials such as (classically) lead oxide (see flint glass and lead glass), or in modern uses, less toxic oxides of zirconium, titanium, or barium. These high-index glasses (inaccurately known as "crystal" when used in glass vessels) cause more chromatic dispersion of light, and are prized for their diamond-like optical properties.
answer:
What can be used to make glass less dense?
