Problem: Royal Dutch Shell:

The name Shell is linked to The "Shell" Transport and Trading Company. In 1833, the founder's father, Marcus Samuel, founded an import business to sell seashells to London collectors. When collecting seashell specimens in the Caspian Sea area in 1892, the younger Samuel realised there was potential in exporting lamp oil from the region and commissioned the world's first purpose-built oil tanker, the Murex (Latin for a type of snail shell), to enter this market; by 1907 the company had a fleet. Although for several decades the company had a refinery at Shell Haven on the Thames, there is no evidence of this having provided the name.

Problem: Mandolin:

There is confusion currently as to the name of the eldest Vinaccia luthier who first ran the shop. His name has been put forth as Gennaro Vinaccia (active c. 1710 to c. 1788) and Nic. Vinaccia. His son Antonio Vinaccia was active c. 1734 to c. 1796. An early extant example of a mandolin is one built by Antonio Vinaccia in 1759, which resides at the University of Edinburgh. Another is by Giuseppe Vinaccia, built in 1893, is also at the University of Edinburgh. The earliest extant mandolin was built in 1744 by Antonio's son, Gaetano Vinaccia. It resides in the Conservatoire Royal de Musique in Brussels, Belgium.

What is there not currently confusion over?

A: unanswerable


Problem: Textual criticism:

Bowers and Tanselle argue for rejecting textual variants that an author inserted at the suggestion of others. Bowers said that his edition of Stephen Crane's first novel, Maggie, presented "the author's final and uninfluenced artistic intentions." In his writings, Tanselle refers to "unconstrained authorial intention" or "an author's uninfluenced intentions." This marks a departure from Greg, who had merely suggested that the editor inquire whether a later reading "is one that the author can reasonably be supposed to have substituted for the former", not implying any further inquiry as to why the author had made the change.

Who argued for works where the author listens to input from others?

A: unanswerable


Problem: LaserDisc:

LaserDisc players can provide a great degree of control over the playback process. Unlike many DVD players, the transport mechanism always obeys commands from the user: pause, fast-forward, and fast-reverse commands are always accepted (barring, of course, malfunctions). There were no "User Prohibited Options" where content protection code instructs the player to refuse commands to skip a specific part (such as fast forwarding through copyright warnings). (Some DVD players, particularly higher-end units, do have the ability to ignore the blocking code and play the video without restrictions, but this feature is not common in the usual consumer market.)

How does LaserDisc operation vary from DVD?
