The principle of the Constitution being demonstrated by this passage is Checks and Balances.

The principle of checks and balances is being demonstrated by this passage. To determine this, we need to analyze the passage and understand how it relates to the concept of checks and balances within the Constitution.

In the passage, it states that "Every Bill which shall have passed the House of Representatives and the Senate, shall, before it become a Law, be presented to the President of the United States." This indicates that the process of making a bill into a law involves multiple branches of government - the legislative branch (House of Representatives and Senate) and the executive branch (President).

Furthermore, the passage states that if the President approves the bill, they shall sign it. However, if the President does not approve the bill, they have the power to return it. This demonstrates a system of checks and balances, as it ensures that the President has the ability to review and potentially veto a bill that they do not agree with, providing a check on the legislative branch's power.

Therefore, based on the passage's mention of the interaction between the legislative branch and the executive branch, and the balance of power exhibited in allowing the President to approve or return the bill, the principle of checks and balances is being demonstrated.
