Answer:
- The president can veto a law passed by Congress.
- The president chooses the Supreme Court Justices.
Step-by-step explanation:
The president is considered as the head of the Executive branch. In government, "Checks" refer to the power that a specific branch of government has to limit the power of other branch of the government.
Congress is part of the legislative branch. The ability to veto a law enable the president to prevent a law proposal made by the Congress from being passed. This is why it's considered as a "Check" belonged to the executive branch to limit the legislative branch.
Supreme Court Justices are part of the judicial branch. By being able to choose the Justices, the president can influence the people that will make the decision in case members of government officials engaged in a conflict. This influence is the reason why it's considered as a "Check" belonged to the executive branch to limit the judicial branch.
