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: The term cardinal at one time applied to any priest permanently assigned or incardinated to a church, or specifically to the senior priest of an important church, based on the Latin cardo (hinge), meaning "principal" or "chief". The term was applied in this sense as early as the ninth century to the priests of the tituli (parishes) of the diocese of Rome. The Church of England retains an instance of this origin of the title, which is held by the two senior members of the College of Minor Canons of St Paul's Cathedral.
answer:
What does the Latin cardo not mean?


question:
Passage: Elizabeth has held many titles and honorary military positions throughout the Commonwealth, is Sovereign of many orders in her own countries, and has received honours and awards from around the world. In each of her realms she has a distinct title that follows a similar formula: Queen of Jamaica and her other realms and territories in Jamaica, Queen of Australia and her other realms and territories in Australia, etc. In the Channel Islands and Isle of Man, which are Crown dependencies rather than separate realms, she is known as Duke of Normandy and Lord of Mann, respectively. Additional styles include Defender of the Faith and Duke of Lancaster. When in conversation with the Queen, the practice is to initially address her as Your Majesty and thereafter as Ma'am.
answer:
What is one of Elizabeth's realms and territories besides Jamaica and Australia?


question:
Passage: Animals are also involved in the distribution of seeds. Fruit, which is formed by the enlargement of flower parts, is frequently a seed-dispersal tool that attracts animals to eat or otherwise disturb it, incidentally scattering the seeds it contains (see frugivory). Although many such mutualistic relationships remain too fragile to survive competition and to spread widely, flowering proved to be an unusually effective means of reproduction, spreading (whatever its origin) to become the dominant form of land plant life.
answer:

What did competition prove to be effective at doing?
