Problem: Compact disc:

The ReWritable Audio CD is designed to be used in a consumer audio CD recorder, which will not (without modification) accept standard CD-RW discs. These consumer audio CD recorders use the Serial Copy Management System (SCMS), an early form of digital rights management (DRM), to conform to the United States' Audio Home Recording Act (AHRA). The ReWritable Audio CD is typically somewhat more expensive than CD-RW due to (a) lower volume and (b) a 3% AHRA royalty used to compensate the music industry for the making of a copy.

What year was the digital rights management published?

A: unanswerable

Problem: Queen Victoria:

Though queen, as an unmarried young woman Victoria was required by social convention to live with her mother, despite their differences over the Kensington System and her mother's continued reliance on Conroy. Her mother was consigned to a remote apartment in Buckingham Palace, and Victoria often refused to see her. When Victoria complained to Melbourne that her mother's close proximity promised "torment for many years", Melbourne sympathised but said it could be avoided by marriage, which Victoria called a "schocking [sic] alternative". She showed interest in Albert's education for the future role he would have to play as her husband, but she resisted attempts to rush her into wedlock.

Whom did Victoria's mother continue to rely on, despite Victoria's displeasure?

A: Conroy

Problem: Group (mathematics):

Symmetry groups are groups consisting of symmetries of given mathematical objectsbe they of geometric nature, such as the introductory symmetry group of the square, or of algebraic nature, such as polynomial equations and their solutions. Conceptually, group theory can be thought of as the study of symmetry.t["] Symmetries in mathematics greatly simplify the study of geometrical or analytical objects. A group is said to act on another mathematical object X if every group element performs some operation on X compatibly to the group law. In the rightmost example below, an element of order 7 of the (2,3,7) triangle group acts on the tiling by permuting the highlighted warped triangles (and the other ones, too). By a group action, the group pattern is connected to the structure of the object being acted on.

What does group action do to the tiling?
