Question

what is the first step toward preventing domestic violence?
call the police.
recognize the warning signs.
review the decision and its consequences.
check a persons criminal background.

Explanation:

To prevent domestic violence, the first step is to be aware of the warning signs (like controlling behavior, threats) as without recognizing them, other actions (calling police, reviewing decisions, checking criminal background) are less effective or premature. "Call the police" is a response during/after violence, "review decision..." is post - action, and "check criminal background" is not a primary prevention step.

Answer:

B. Recognize the warning signs.
