Which does a reference point provide

A. A position from which to measure future distance.

Explanation: It should be the answer, because my notes say that a reference point is a location or object used for comparison to determine another location (purpose: to establish a point from which to measure future distance, or if movement has occurred).

Hope this helped. :)

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
