Question

which does a reference point provide?
a position from which to measure future distance
a set of standard units for measuring displacement
a standard method for evaluating variables
a method for determining the speed of an object

Explanation:

A reference point is a fixed - point used as a basis for comparison to measure distances or positions of other objects. It provides a starting position from which future distances can be measured. It has nothing to do with standard units for displacement, method for evaluating variables, or determining speed.

Answer:

a position from which to measure future distance
