  Title: A&amp;W Cream Soda
  Passage: A&W Cream Soda is a cream soda carbonated soft drink introduced by A&W Root Beer in 1986.  A&W Root Beer was first sold at a Veterans Day parade in Lodi, California in 1919 and the company established in 1922 by Frank Wright and Roy Allen.  The first product they created was A & W Root Beer.  It was not until 1986 that A&W Brands, headquartered in White Plains, N.Y. introduced A&W Cream Soda and A&W Diet Cream Soda through its network of franchised bottlers and distributors.  Although cream soda had been created in 1852 by E.M. Sheldon, A&W Brands was one of the first American companies to make it commercially.  In 1993, A&W Brands was purchased by Cadbury/Schweppes, and in 1995 Cadbury/Schweppes purchased the Dr. Pepper/Seven-Up Company, which made A&W a part of the Dr. Pepper/Seven Up, Inc.  In 2001, DPSU purchased the Snapple Beverage Group (formally TriArc Beverages), and moved the New York-based company operations to its new headquarters in Plano, Texas.  This acquisition put A&W within the same company as the top soda brand companies and made A&W Cream Soda the top brand in cream sodas.

  Title: Root beer
  Passage: Root beer is a sweet North American soft drink traditionally made using the sassafras tree "Sassafras albidum" (sassafras) or the vine "Smilax ornata" (sarsaparilla) as the primary flavor.  Root beer may be alcoholic or non-alcoholic, come naturally free of caffeine or have caffeine added, and carbonated or non-carbonated.  It usually has a thick, foamy head when poured.  Modern, commercially produced root beer is generally sweet, foamy, carbonated, nonalcoholic, and flavoured using artificial sassafras flavouring.  Sassafras root is still used to flavor traditional root beer, but since sassafras was banned by the U.S. Food and Drug Administration due to the controversially claimed carcinogenicity of its constituent safrole, most commercial recipes do not contain sassafras.  Some commercial root beers do use a safrole-free sassafras extract.
