Question

all new supreme court justices must be nominated by the president. which arrow on the diagram stands for this check on judicial power?

Explanation:

The problem is about the separation of powers and checks and balances in the US government. The president (Executive branch) nominates Supreme Court justices (Judicial branch). So we need to find the arrow from Executive to Judicial. Looking at the diagram, the arrows: the ones between Executive and Judicial—we need the arrow where Executive acts on Judicial (nominating, which is Executive to Judicial). Wait, no—wait, the president is Executive, nominating to Judicial. So the arrow from Executive to Judicial? Wait, looking at the diagram: Executive has arrows to Judicial? Wait the diagram has Executive at top, Judicial at bottom left, Legislative at bottom right. The arrows: between Executive and Judicial, there are two arrows (one up, one down? Wait no, the arrows: from Judicial to Executive (up arrow), and Executive to Judicial (down arrow? Wait no, the blue arrows: let's see, the arrows between Executive and Judicial: one arrow going from Judicial to Executive, and one from Executive to Judicial? Wait no, the user's diagram: "Executive" at top, "Judicial" at bottom left, "Legislative" at bottom right. The arrows: between Executive and Judicial: two arrows (one pointing to Executive, one pointing to Judicial? Wait no, the original diagram: the arrows are blue. Let's parse: the problem is about Executive (president) nominating to Judicial (Supreme Court). So the check is Executive (president) acting on Judicial (nominating justices). So the arrow from Executive to Judicial. Looking at the diagram, the arrows between Executive and Judicial: which one is that? Wait the arrows: between Executive and Judicial: one arrow from Judicial to Executive, and one from Executive to Judicial? Wait the user's diagram: "All new Supreme Court justices must be nominated by the president"—so Executive (president) → Judicial (Supreme Court). So the arrow from Executive to Judicial. In the diagram, the arrows: let's see, the arrows: from Executive to Judicial—wait, the diagram has arrows: between Executive and Judicial, two arrows? Wait no, the user's diagram: "Executive" at top, "Judicial" at bottom left, "Legislative" at bottom right. The arrows: between Executive and Judicial: one arrow going from Judicial to Executive (upwards), and one from Executive to Judicial (downwards)? Wait no, the blue arrows: let's look at the directions. The problem is about Executive (president) nominating to Judicial (Supreme Court), so the arrow from Executive to Judicial. So in the diagram, the arrow that is from Executive (top) to Judicial (bottom left). So that's the arrow from Executive to Judicial. So the answer is the arrow from Executive to Judicial (the one pointing from Executive to Judicial).

Answer:

The arrow from the "Executive" circle to the "Judicial" circle (representing the Executive branch's power to nominate Supreme Court justices, a check on judicial power).
