TASK DEFINITION: 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.
PROBLEM: Passage: At the time, the Umayyad taxation and administrative practice were perceived as unjust by some Muslims. The Christian and Jewish population had still autonomy; their judicial matters were dealt with in accordance with their own laws and by their own religious heads or their appointees, although they did pay a poll tax for policing to the central state. Muhammad had stated explicitly during his lifetime that abrahamic religious groups (still a majority in times of the Umayyad Caliphate), should be allowed to practice their own religion, provided that they paid the jizya taxation. The welfare state of both the Muslim and the non-Muslim poor started by Umar ibn al Khattab had also continued. Muawiya's wife Maysum (Yazid's mother) was also a Christian. The relations between the Muslims and the Christians in the state were stable in this time. The Umayyads were involved in frequent battles with the Christian Byzantines without being concerned with protecting themselves in Syria, which had remained largely Christian like many other parts of the empire. Prominent positions were held by Christians, some of whom belonged to families that had served in Byzantine governments. The employment of Christians was part of a broader policy of religious assimilation that was necessitated by the presence of large Christian populations in the conquered provinces, as in Syria. This policy also boosted Muawiya's popularity and solidified Syria as his power base.

SOLUTION: What populations did not have autonomy?

PROBLEM: Passage: In July 1977, General Zia-ul-Haq overthrew Prime Minister Zulfiqar Ali Bhutto's regime in Pakistan. Ali Bhutto, a leftist in democratic competition with Islamists, had announced banning alcohol and nightclubs within six months, shortly before he was overthrown. Zia-ul-Haq was much more committed to Islamism, and "Islamization" or implementation of Islamic law, became a cornerstone of his eleven-year military dictatorship and Islamism became his "official state ideology". Zia ul Haq was an admirer of Mawdudi and Mawdudi's party Jamaat-e-Islami became the "regime's ideological and political arm". In Pakistan this Islamization from above was "probably" more complete "than under any other regime except those in Iran and Sudan," but Zia-ul-Haq was also criticized by many Islamists for imposing "symbols" rather than substance, and using Islamization to legitimize his means of seizing power. Unlike neighboring Iran, Zia-ul-Haq's policies were intended to "avoid revolutionary excess", and not to strain relations with his American and Persian Gulf state allies. Zia-ul-Haq was killed in 1988 but Islamization remains an important element in Pakistani society.

SOLUTION: When was the regime in Pakistan accepted by General Zia-ul-Haq?

PROBLEM: Passage: One-color light is well suited for traffic lights and signals, exit signs, emergency vehicle lighting, ships' navigation lights or lanterns (chromacity and luminance standards being set under the Convention on the International Regulations for Preventing Collisions at Sea 1972, Annex I and the CIE) and LED-based Christmas lights. In cold climates, LED traffic lights may remain snow-covered. Red or yellow LEDs are used in indicator and alphanumeric displays in environments where night vision must be retained: aircraft cockpits, submarine and ship bridges, astronomy observatories, and in the field, e.g. night time animal watching and military field use.

SOLUTION:
 What type of light is not ideal for traffic signals?
