Which of the following are preventative measures for guiding behavior?

A) Do not prepare the environment
B) Allow the environment to provide the limits
C) Distract children
D) Discourage children from expressing feelings

Allowing the environment to provide limits is a preventative measure for guiding behavior. This means that the environment is set up in a way that promotes positive behavior and reduces the likelihood of negative behavior. Choosing not to prepare the environment or distracting children are not helpful preventative measures, and discouraging children from expressing their feelings can lead to negative behaviors.
