Input: Read this: The personal copying exemption in the copyright law of EU member states stems from the EU Copyright Directive of 2001, which is generally devised to allow EU members to enact laws sanctioning making copies without authorization, as long as they are for personal, noncommerical use. The Copyright Directive was not intended to legitimize file-sharing, but rather the common practice of space shifting copyright-protected content from a legally purchased CD (for example) to certain kinds of devices and media, provided rights holders are compensated and no copy protection measures are circumvented. Rights-holder compensation takes various forms, depending on the country, but is generally either a levy on "recording" devices and media, or a tax on the content itself. In some countries, such as Canada, the applicability of such laws to copying onto general-purpose storage devices like computer hard drives, portable media players, and phones, for which no levies are collected, has been the subject of debate and further efforts to reform copyright law.
Question: Compensation to the rights-holder is generally a levy or what else?

Output: a tax on the content itself

Input: Read this: At this time, Hal B. Wallis, who had latterly worked as a major producer at Paramount, moved over to Universal, where he produced several films, among them a lavish version of Maxwell Anderson's Anne of the Thousand Days (1969), and the equally lavish Mary, Queen of Scots (1971). Though neither could claim to be a big financial hit, both films received Academy Award nominations, and Anne was nominated for Best Picture, Best Actor (Richard Burton), Best Actress (Genevieve Bujold), and Best Supporting Actor (Anthony Quayle). Wallis retired from Universal after making the film Rooster Cogburn (1975), a sequel to True Grit (1969), which Wallis had produced at Paramount. Rooster Cogburn co-starred John Wayne, reprising his Oscar-winning role from the earlier film, and Katharine Hepburn, their only film together. The film was only a moderate success.
Question: In what year was the film version of Mary, Queen of Scots made?

Output: 1971

Input: Read this: A group is called finite if it has a finite number of elements. The number of elements is called the order of the group. An important class is the symmetric groups SN, the groups of permutations of N letters. For example, the symmetric group on 3 letters S3 is the group consisting of all possible orderings of the three letters ABC, i.e. contains the elements ABC, ACB, ..., up to CBA, in total 6 (or 3 factorial) elements. This class is fundamental insofar as any finite group can be expressed as a subgroup of a symmetric group SN for a suitable integer N (Cayley's theorem). Parallel to the group of symmetries of the square above, S3 can also be interpreted as the group of symmetries of an equilateral triangle.
Question: What are the group of symmetries of a S3?

Output: unanswerable

Input: Read this: Genome composition is used to describe the make up of contents of a haploid genome, which should include genome size, proportions of non-repetitive DNA and repetitive DNA in details. By comparing the genome compositions between genomes, scientists can better understand the evolutionary history of a given genome.
Question: By comparing repetitive DNA, what can scientists understand the history of?

Output:
unanswerable
