Final answer:
The statement regarding managers and legal knowledge preventing legal situations is false. A theory doesn't become law simply because it's been known for a long time, again false. The necessary and proper clause expands national government power, and Dillon's Rule restricts local government powers, both statements are false.
Step-by-step explanation:
The statement "As long as a manager has a good knowledge of the law, it is not very important to be concerned with attempting to prevent legal situations from arising." is false. While having a good knowledge of law is beneficial, it is also crucial for managers to be proactive in preventing legal issues before they arise. This involves creating and enforcing policies and practices that comply with laws, providing training to employees to ensure they understand legal obligations, and staying updated with changes in laws to mitigate risks. Additionally, when a theory has been known for a long time, it does not necessarily become a law; this is a false assumption.
Concerning Exercise 9.3.1, the necessary and proper clause, also known as the elastic clause, allows Congress to make laws that are necessary and proper for carrying out its powers. Contrary to limiting, it has the effect of expanding the power of the national government. Hence, the statement is false.
Dillon's Rule, it indicates that local governments only have powers that are expressly granted to them by state law, the state constitution, or implied through the express powers. Therefore, Dillon's Rule does not give local governments the freedom and flexibility to make decisions for themselves, and the statement is false.
