What are examples of actions taken by Congress that were not based on the Elastic Clause? I NEED HELP IT IS URGENT

The Elastic Clause of the United States Constitution, inserted in its Article I, Section 8, empowers the federal Congress to take the measures and carry out the necessary actions to guarantee the normal performance of its explicit powers, that is, those that are written in the Constitution. Thus, the Elastic Clause expands the powers of Congress.

Now, many prerogatives of Congress are found in the text of the Constitution itself, which does not arise from the Elastic Clause. A clear example of this is the power to declare war, or the power to establish lower courts than the Supreme Court.
