Final answer:
A promise to perform a future action can be considered valid consideration in a contract, which is true. Regarding the necessary and proper clause, it is false that it limits the national government's power; rather, it expands it by allowing Congress to pass laws deemed necessary and proper.
Step-by-step explanation:
For the purpose of contract information, the statement that a promise to perform a particular action in the future can constitute consideration is A. True. Consideration is a fundamental element of a legally binding contract and refers to something of value that is exchanged between the parties involved. A valid consideration can be a promise to do something.
In regards to the second question, the correct answer to whether the necessary and proper clause has had the effect of limiting the power of the national government is B. FALSE. The Necessary and Proper Clause, which is found in Article I, Section 8 of the Constitution, effectively expands the powers of the national government by granting Congress the authority to make all laws deemed necessary and proper for carrying out its duties.
