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.

[Q]: Passage: Gun usage in hunting is typically regulated by game category, area within the state, and time period. Regulations for big-game hunting often specify a minimum caliber or muzzle energy for firearms. The use of rifles is often banned for safety reasons in areas with high population densities or limited topographic relief. Regulations may also limit or ban the use of lead in ammunition because of environmental concerns. Specific seasons for bow hunting or muzzle-loading black-powder guns are often established to limit competition with hunters using more effective weapons.
[A]: By what category is bow hunting regulated?


[Q]: 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%).
[A]: What is used to eliminate the metal zinc?


[Q]: Passage: In sheer numbers, Kerry had fewer endorsements than Howard Dean, who was far ahead in the superdelegate race going into the Iowa caucuses in January 2004, although Kerry led the endorsement race in Iowa, New Hampshire, Arizona, South Carolina, New Mexico and Nevada. Kerry's main perceived weakness was in his neighboring state of New Hampshire and nearly all national polls. Most other states did not have updated polling numbers to give an accurate placing for the Kerry campaign before Iowa. Heading into the primaries, Kerry's campaign was largely seen as in trouble, particularly after he fired campaign manager Jim Jordan. The key factors enabling it to survive were when fellow Massachusetts Senator Ted Kennedy assigned Mary Beth Cahill to be the campaign manager, as well as Kerry's mortgaging his own home to lend the money to his campaign (while his wife was a billionaire, campaign finance rules prohibited using one's personal fortune). He also brought on the "magical" Michael Whouley who would be credited with helping bring home the Iowa victory the same as he did in New Hampshire for Al Gore in 2000 against Bill Bradley.
[A]:
What did Ted Kennedy have fewer of than Kerry in 2004?
