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: Zinc metal is produced using extractive metallurgy. After grinding the ore, froth flotation, which selectively separates minerals from gangue by taking advantage of differences in their hydrophobicity, is used to get an ore concentrate. This concentrate consists of about 50% zinc with the rest being sulfur (32%), iron (13%), and SiO
2 (5%). The composition of this is normally zinc sulfide (80% to 85%), iron sulfide (7.0% to 12%), lead sulfide (3.0% to 5.0%) silica (2.5% to 3.5%), and cadmium sulfide (0.35% to 0.41%).

SOLUTION: What is used to eliminate the metal zinc?

PROBLEM: Passage: When a person’s capabilities are lowered, they are in some way deprived of earning as much income as they would otherwise. An old, ill man cannot earn as much as a healthy young man; gender roles and customs may prevent a woman from receiving an education or working outside the home. There may be an epidemic that causes widespread panic, or there could be rampant violence in the area that prevents people from going to work for fear of their lives. As a result, income and economic inequality increases, and it becomes more difficult to reduce the gap without additional aid. To prevent such inequality, this approach believes it’s important to have political freedom, economic facilities, social opportunities, transparency guarantees, and protective security to ensure that people aren’t denied their functionings, capabilities, and agency and can thus work towards a better relevant income.

SOLUTION: What happens when a person's capabilities aer raised, as it relates to their income?

PROBLEM: Passage: Medievalist specialists who define the university as a legally autonomous corporation disagree with the term "university" for the Islamic madaris and jāmi‘ahs because the medieval university (from Latin universitas) was structurally different, being a legally autonomous corporation rather than a waqf institution like the madrasa and jāmiʻah. Despite the many similarities, medieval specialists have coined the term "Islamic college" for madrasa and jāmiʻah to differentiate them from the legally autonomous corporations that the medieval European universities were. In a sense, the madrasa resembles a university college in that it has most of the features of a university, but lacks the corporate element. Toby Huff summarises the difference as follows:

SOLUTION:
What do scholars believe is included from madaris that guarantees them being considered universities?
