Final answer:
The text provided does not specify a date for the enactment of the Merchant Marine Act. Various acts affecting maritime trade and legislation are mentioned, but they do not align with the Merchant Marine Act's enactment date.
Step-by-step explanation:
The question concerns the enactment of the Merchant Marine Act. However, the provided text does not specify an exact date for the Merchant Marine Act's enactment. Thus, I cannot provide an accurate date for it within this context. Given that various Merchant Marine Acts were passed throughout history, including a notable one in 1920 (not mentioned in your text), it is essential for students to have precise information. In historical legislation, the Merchandise Act, Prohibitory Act, and actions relating to maritime activities during the Revolutionary War period and instances of the Legal Tender Act are discussed. For example, the Prohibitory Act in 1776 and the aggressive actions of the British Navy resulted in Congress allowing the seizure of British ships as a retaliatory measure. However, these are not directly related to the specific Merchant Marine Act in question.
