Final answer:
The question deals with the prohibition of unethical advertising practices in business, specifically relating to real estate. Such practices are monitored by the Federal Trade Commission (FTC) to prevent deceptive advertising. The principle of 'caveat emptor' reminds consumers to remain vigilant.
Step-by-step explanation:
The subject of the question pertains to ethical practices and regulations in the context of business and advertising, more specifically related to real estate transactions. In terms of business ethics and advertising regulations, Article 4 mentioned in the question likely refers to some form of regulatory or ethical code that demands honest advertising practices, which means no exaggeration, misrepresentation, or concealment of essential facts about a property or the transaction.
Adherence to such regulations is underscored by the oversight of the Federal Trade Commission (FTC), which monitors factual claims to prevent deceptive advertising. This is coupled with the concept of caveat emptor, or 'let the buyer beware', reminding consumers of their responsibility in making informed purchasing decisions. Furthermore, laws may compel businesses to provide transparent information, as is the case with the disclosure of nutritional information on products or the inclusion of all taxes in advertised airline ticket prices.
