Final answer:
False The Securities Act of 1933 makes it illegal to sell securities without disclosing financial information, regardless of whether interstate transportation or mail systems are used.
Step-by-step explanation:
The statement is false.
The Securities Act of 1933 does not differentiate between the use of interstate transportation or mail systems when it comes to selling securities without disclosing financial information to potential investors. It is illegal to engage in such activities through both interstate transportation and mail systems.
The act aims to protect investors by ensuring that they have access to accurate and complete financial information before making investment decisions.
