TASK DEFINITION: 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

PROBLEM: Passage: The principles of imperialism are often generalizable to the policies and practices of the British Empire "during the last generation, and proceeds rather by diagnosis than by historical description". British imperialism often used the concept of Terra nullius (Latin expression which stems from Roman law meaning 'empty land'). The country of Australia serves as a case study in relation to British settlement and colonial rule of the continent in the eighteenth century, as it was premised on terra nullius, and its settlers considered it unused by its sparse Aboriginal inhabitants.

SOLUTION: Imperialism is less often associated with which sovereignty?

PROBLEM: Passage: The first union was built on campus in 1926 as a campus community center. The unions are still the "living rooms" of campus today and include three locations the Kansas Union and Burge Union at the Lawrence Campus and Jayhawk Central at the Edwards Campus. The KU Memorial Unions Corporation manages the KU Bookstore (with seven locations). The KU Bookstore is the official bookstore of KU. The Corporation also includes KU Dining Services, with more than 20 campus locations, including The Market (inside the Kansas Union) and The Underground (located in Wescoe Hall). The KU Bookstore and KU Dining Services are not-for-profit, with proceeds going back to support student programs, such as Student Union Activities.

SOLUTION: When was KU's last student union constructed?

PROBLEM: Passage: The growth of the Internet, and particularly distributed search engines like Kazaa and Gnutella, have represented a challenge for copyright policy. The Recording Industry Association of America, in particular, has been on the front lines of the fight against copyright infringement, which the industry calls "piracy". The industry has had victories against some services, including a highly publicized case against the file-sharing company Napster, and some people have been prosecuted for sharing files in violation of copyright. The electronic age has seen an increase in the attempt to use software-based digital rights management tools to restrict the copying and use of digitally based works. Laws such as the Digital Millennium Copyright Act have been enacted, that use criminal law to prevent any circumvention of software used to enforce digital rights management systems. Equivalent provisions, to prevent circumvention of copyright protection have existed in EU for some time, and are being expanded in, for example, Article 6 and 7 the Copyright Directive. Other examples are Article 7 of the Software Directive of 1991 (91/250/EEC), and the Conditional Access Directive of 1998 (98/84/EEC). This can hinder legal uses, affecting public domain works, limitations and exceptions to copyright, or uses allowed by the copyright holder. Some copyleft licenses, like GNU GPL 3, are designed to counter that. Laws may permit circumvention under specific conditions like when it is necessary to achieve interoperability with the circumventor's program, or for accessibility reasons; however, distribution of circumvention tools or instructions may be illegal.

SOLUTION:
The growth of what has strengthened copyright policy?
