Final answer:
Whether authorized stores must display a Sandy's Law poster is dependent on specific legal requirements that were not provided in the question. Generally, laws require businesses to display certain information, such as consumer protection notices and employment rights, as regulated by the FTC and OSHA respectively.
Step-by-step explanation:
The statement "Authorized stores must display a Sandy's Law poster" is true or false cannot be determined without additional context specific to Sandy's Law and the jurisdiction it pertains to. However, it is common for governments at various levels to mandate the posting of certain information in businesses. These mandated postings may relate to consumer protection, such as the requirement of disclosing nutritional information on food and beverage containers, warning labels on tobacco products, and complete pricing on airline tickets, as well as professional regulations like those for lawyer advertising. These laws are designed to ensure that businesses conduct transparent and ethical operations, preventing misleading or fraudulent representations to the consumer.
One such example at the federal level is the mandate by the Occupational Safety and Health Administration (OSHA) requiring employers to display the "Job Safety and Health: It's the Law" poster to inform workers of their rights and protections. Similarly, the Federal Trade Commission (FTC) plays a role in checking factual claims about product performances in advertising, to prevent the dissemination of untrue "facts" which are not permitted, as per the principle of Caveat emptor - "let the buyer beware".
