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 motif of the England national football team has three lions passant guardant, the emblem of King Richard I, who reigned from 1189 to 1199. The lions, often blue, have had minor changes to colour and appearance. Initially topped by a crown, this was removed in 1949 when the FA was given an official coat of arms by the College of Arms; this introduced ten Tudor roses, one for each of the regional branches of the FA. Since 2003, England top their logo with a star to recognise their World Cup win in 1966; this was first embroidered onto the left sleeve of the home kit, and a year later was moved to its current position, first on the away shirt.

Answer: In what year was King Richard I born?


Question: Passage: Greek drama exemplifies the earliest form of drama of which we have substantial knowledge. Tragedy, as a dramatic genre, developed as a performance associated with religious and civic festivals, typically enacting or developing upon well-known historical or mythological themes. Tragedies generally presented very serious themes. With the advent of newer technologies, scripts written for non-stage media have been added to this form. War of the Worlds (radio) in 1938 saw the advent of literature written for radio broadcast, and many works of Drama have been adapted for film or television. Conversely, television, film, and radio literature have been adapted to printed or electronic media.

Answer: The earliest form of drama we know about is from the Roman and what other culture?


Question: Passage: Leukocytes (white blood cells) act like independent, single-celled organisms and are the second arm of the innate immune system. The innate leukocytes include the phagocytes (macrophages, neutrophils, and dendritic cells), mast cells, eosinophils, basophils, and natural killer cells. These cells identify and eliminate pathogens, either by attacking larger pathogens through contact or by engulfing and then killing microorganisms. Innate cells are also important mediators in the activation of the adaptive immune system.

Answer:
What cells can't act independently?
