Final answer:
Classified meeting invitations for foreign persons are indeed sent by the sponsoring government agency. The necessary and proper clause has expanded, not limited, Congress's power. Colonial governors indeed had the right to veto legislation passed by colonial assemblies.
Step-by-step explanation:
The statement that classified meeting invitations to foreign persons must be sent by the authorizing or sponsoring government agency is true. Classified information and meetings about such information are strictly controlled by governmental protocols. These protocols ensure that sensitive information is only accessible to individuals who have the necessary security clearance and need-to-know basis. The process of vetting and authorizing foreign individuals for access to classified meetings includes numerous security measures and is always overseen by the appropriate government agency.
In regards to Exercise 9.3.1, the necessary and proper clause, also known as the elastic clause, has not had the effect of limiting the power of the national government; rather, it has been interpreted to grant Congress the flexibility to use powers not explicitly named in the Constitution if they are deemed necessary and proper to execute its constitutionally enumerated powers. Thus, the correct answer is false.
Concerning colonial governors and their power, it is true that they had the right to veto legislation passed by the colonial assemblies. This was one aspect of control that the British crown maintained over the colonies, ensuring that colonial legislation aligned with the crown’s interests.
