And "string" is just fancy programmer speak for "text" (data composed of
sequential characters). And you define text by wrapping it in quotation
marks, hence, as Jeremy said:

require "benchmark"


require is code -- it tells the interpreter to call the method named require
(methods are just pieces of code that have been named, and can be executed
over and over).

"benchmark" is data -- the interpreter knows it is text (a string) and gives
it to the require method.
