Teacher: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:

(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.
Teacher: Now, understand the problem? Solve this instance: Passage: Weeks after ending the Sex Pistols, Lydon formed the experimental group Public Image Ltd and declared the project to be "anti music of any kind". Public Image and other acts such as the Pop Group and the Slits had begun experimenting with dance music, dub production techniques and the avant-garde, while punk-indebted Manchester acts such as Joy Division, The Fall and A Certain Ratio developed unique styles which drew on a similarly disparate range of influences across music and modernist literature. Bands such as Scritti Politti, Gang of Four and This Heat incorporated Leftist political philosophy and their own art school studies in their work.
Student:
What group did Lyndon start before the sex pistols?
