Which does a reference point provide? Select two options. 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 a way to detect an object’s motion

hope this helps you :)

Explanation:

An object is in motion if its position changes relative to another object. To decide if you are moving, you can use your chair as a reference point. A reference point is a place or object used for comparison to determine if something is in motion.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
