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:
(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.
Teacher: Now, understand the problem? Solve this instance: Passage: LeGrande writes that "the formulation of a single all-encompassing definition of the term is extremely difficult, if not impossible. In reviewing the voluminous literature on the subject, the student of civil disobedience rapidly finds himself surrounded by a maze of semantical problems and grammatical niceties. Like Alice in Wonderland, he often finds that specific terminology has no more (or no less) meaning than the individual orator intends it to have." He encourages a distinction between lawful protest demonstration, nonviolent civil disobedience, and violent civil disobedience.
Student:
Who wrote that its difficult to formulate a definition of grammatical niceties?
