One of the MOST Important Reasons for Writing a Precise

One of the MOST important reasons for writing a precise definition of behavior is that a precise definition:

A) produces greater interobserver agreement and requires less training time for observers.
B) allows for easier and more reliable quantification of temporal locus and temporal extent.
C) increases the likelihood that the behavior of interest will be reliably detected by observers or measurement equipment.
D) makes calibration checks of observers or measurement equipment less necessary.
