In the question below, a passage is given followed by three statements. You must determine which combination of the statements WEAKENS the argument presented. Argument: Quantum encryption is being promoted as the ultimate solution for securing global financial transactions against cyber-attacks. Experts claim that adopting quantum-resistant algorithms will completely eliminate data breaches and ensure the total privacy of digital assets across the banking sector. Which of the following statements, if true, would WEAKEN the argument?
I. The specialized hardware required for quantum encryption requires extremely low temperatures, leading to massive electricity consumption and infrastructure costs.
II. Current high-level encryption standards are already capable of protecting 99% of transactions against present-day hacking methods.
III. Integrating quantum encryption into existing legacy banking systems is technically complex and requires an investment of capital that many smaller banks cannot afford.

The Argument: The claim is that quantum encryption is the "ultimate solution" to eliminate breaches globally. Statement I (Weakens): This mirrors your "energy consumption and sustainability concerns" logic. It identifies a significant resource and infrastructure hurdle (cooling/electricity) that challenges the feasibility of widespread, global adoption. Statement III (Weakens): This mirrors your "complex technical knowledge and high upfront costs" logic. By highlighting that the transition is technically difficult and financially prohibitive for many institutions, it undermines the claim that this technology can be a universal, sector-wide solution. Statement II (Neutral): This mirrors your "existing systems provide partial traceability" logic. Simply stating that current systems are "good enough" for now does not disprove the claim that a new, superior technology (quantum encryption) would be the ultimate solution for the future. It describes the status quo rather than attacking the effectiveness of the proposed solution.
