Which of the following best describes the restrictions placed by the Federal Campaign Act of 1974?

The Federal Campaign Act of 1974 established important regulations to govern campaign financing to ensure transparency and limit the potential influence of money in politics. While it did impose restrictions on the amount of money individuals and groups could contribute to political campaigns, the emphasis in the act was on creating clear guidelines about the transparency of contributions and the reporting of campaign finances.

This includes requiring campaigns to disclose the sources of their funding, thereby allowing the public to understand who is financing the political candidates and their campaigns, which can inherently affect policy decisions. It aimed to promote fairness in the electoral process by making the influence of money on politics more visible and thereby holding candidates accountable to their constituents.

The other choices do not accurately reflect the intentions and stipulations of the Federal Campaign Act. For instance, the Act did not allow unlimited contributions, nor did it prohibit donations entirely; instead, it set limits. Moreover, while the Act aimed for fairness, it didn't mandate media coverage to be fair and unbiased, which would fall under different regulatory considerations.
