Answer: Q introduces the initial action: depositing money. P gives the name 'fractional-reserve banking' to the system that follows. S explains the economic effect of 'This process'. R provides the details of how the money is loaned out, which underpins the entire system, but the logical flow from Q to P (defining the system) and then explaining its effect (S) is very strong. However, QRPS is also plausible. Let's re-evaluate. Q (deposit) -> R (bank loans it out) -> S (this process creates money) -> P (this system is called...). The sequence QRSP is more linear and descriptive of the process itself. Let's stick with QRSP. Q -> R -> S -> P. Q: Deposit. R: What the bank does. S: The effect of what the bank does. P: The name for this system. Yes, QRSP seems more logical. Let me recheck D. QPSR. Q: deposit. P: name of system. S: effect. R: details. This is less chronological. QRSP is better. Let me fix my answer. Correct order is QRSP. Q describes the initial action. R explains what the bank does with the deposit. S explains the consequence of this action (money creation). P gives the formal name for this entire system described in Q, R, and S.
