 Question: can you have a heart attack from laughing Context: The first section of the Canal de Franche-Comté was authorised by Burgundy Council in 1783 and completed in 1802 from the Saône to Dôle. Napoleon was seeking to develop inland waterway connections throughout the country, and the Rhône-Rhine link was of such strategic importance that he gave his name to the project. The Emperor's administration conceived the predecessor of today's public-private partnership model, selling existing canals to private companies, to provide funds for new links. The proceeds were diverted for the war effort, and it was not until 1821 that this project, now renamed 'Canal Monsieur', was reactivated by the canal company set up for this purpose. Works were completed in 1833. Upgrading to Freycinet standards started in 1882, and the summit level was lowered, reducing the number of locks. The new high-capacity Rhine-Rhône waterway would have made the canal obsolete, but the environment minister Dominique Voynet cancelled that project in 1997. The Government then funded -- as compensation -- the backlog of maintenance works and other improvements, but with little impact on commercial traffic in 250-tonne péniches, which has all but disappeared.
 Question: is the rhine and the rhone the same river Context: Rye bread is a type of bread made with various proportions of flour from rye grain. It can be light or dark in color, depending on the type of flour used and the addition of coloring agents, and is typically denser than bread made from wheat flour. It is higher in fiber than white bread and is often darker in color and stronger in flavor.
 Question: is rye bread the same as white bread Context: In accounting, gross profit, gross margin, sales profit, or credit sales is the difference between revenue and the cost of making a product or providing a service, before deducting overheads, payroll, taxation, and interest payments. This is different from operating profit (earnings before interest and taxes). Gross margin is the term normally used in the U.S., while gross profit is the more common usage in the UK and Australia.
 Question: is sales revenue and gross profit the same thing Context: The spiny dogfish, spurdog, mud shark, or piked dogfish (Squalus acanthias) is one of the best known species of the Squalidae (dogfish) family of sharks, which is part of the Squaliformes order. While these common names may apply to several species, Squalus acanthias is distinguished by having two spines (one anterior to each dorsal fin) and lacks an anal fin. It is found mostly in shallow waters and further offshore in most parts of the world, especially in temperate waters. Spiny dogfish in the northern Pacific Ocean have recently been reevaluated and found to constitute a separate species, now known as ``Pacific spiny dogfish'', Squalus suckleyi.
