Final answer:
The statement about the escape clause is true, as it allows buyers to waive the contingency of selling their home. Conversely, the idea that the necessary and proper clause limits national government power is false, as it allows Congress to carry out its powers expansively.
Step-by-step explanation:
The statement that an "escape" clause could result in the buyers deciding to waive the condition for the sale of their property even though their property has not sold is true. An escape clause, also known as a kick-out clause, gives sellers the right to continue marketing a home while under contract if the buyers must sell their own home first to complete the purchase. If the sellers receive another offer, the original buyers may need to choose to waive their contingency of selling their existing home or risk losing the property to the new buyers. In contrast, Exercise 9.3.1 suggests the necessary and proper clause has limited the power of the national government, which is false. The necessary and proper clause, often referred to as the elastic clause, actually provides Congress with the flexibility to execute its enumerated powers proficiently, enabling it to adapt to changing needs and circumstances, which contributes to an expansion of the national government's power.
