Answer to Question 1

C

Answer to Question 2

Strictly speaking, requirements should identify only the features that a product must have. In practice, however, descriptions of the problem, guidelines for solving the problem, and product specifications are also thrown into the mix. While we have emphasized that you must discover the true requirements, do not disregard the non-pure elements. Also, requirements are often used in a general sense: what is necessary to do something or a prerequisite. We must rely on the context to distinguish between the two meanings.
