Final answer:
Duty-based ethical standards often come from religious precepts or through philosophical reasoning.
Step-by-step explanation:
The statement that duty-based ethical standards often come from religious precepts or through philosophical reasoning is true.
Duty-based ethics, also known as deontological ethics, focus on duties and moral obligations rather than the consequences of actions.
These ethical standards can be derived from religious teachings, such as the Ten Commandments, or from philosophical theories like Immanuel Kant's categorical imperative.
