Detailed Instructions: 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.
See one example below:
Problem: Passage: In 1763, Spain traded Florida to the Kingdom of Great Britain for control of Havana, Cuba, which had been captured by the British during the Seven Years' War. It was part of a large expansion of British territory following the country's victory in the Seven Years' War. Almost the entire Spanish population left, taking along most of the remaining indigenous population to Cuba. The British soon constructed the King's Road connecting St. Augustine to Georgia. The road crossed the St. Johns River at a narrow point, which the Seminole called Wacca Pilatka and the British named "Cow Ford", both names ostensibly reflecting the fact that cattle were brought across the river there.
Solution: Who owned Cuba after the Eight Years War?
Explanation: This question appears to be relevant to the passage as both involves words such as 'Cuba' and 'War' which also exist in the passage. The passage mentions that "after the war, almost the entire Spanish population left, taking along most of the remaining indigenous population to Cuba". This information is not sufficient to conclude that which country owned cuba.

Problem: Passage: Miami is home to one of the largest ports in the United States, the PortMiami. It is the largest cruise ship port in the world. The port is often called the "Cruise Capital of the World" and the "Cargo Gateway of the Americas". It has retained its status as the number one cruise/passenger port in the world for well over a decade accommodating the largest cruise ships and the major cruise lines. In 2007, the port served 3,787,410 passengers. Additionally, the port is one of the nation's busiest cargo ports, importing 7.8 million tons of cargo in 2007. Among North American ports, it ranks second only to the Port of South Louisiana in New Orleans in terms of cargo tonnage imported/exported from Latin America. The port is on 518 acres (2 km2) and has 7 passenger terminals. China is the port's number one import country, and Honduras is the number one export country. Miami has the world's largest amount of cruise line headquarters, home to: Carnival Cruise Lines, Celebrity Cruises, Norwegian Cruise Line, Oceania Cruises, and Royal Caribbean International. In 2014, the Port of Miami Tunnel was completed and will serve the PortMiami.
Solution:
Along with "Cargo Gateway of the Americas," what isn't another nickname for PortMiami?
