A telecommunications provider observed a 25% drop in subscriber churn in service areas where it concurrently upgraded its cell tower network to 5G and introduced a free device-protection plan for long-term contract holders. Company executives concluded that the speed improvements from the 5G upgrades were directly responsible for the reduction in subscriber churn. Which of the following statements, if true, provide valid logical evaluations that weaken the executives' causal conclusion? (Select all that apply.)

Prior to 2022, any corporate entity acquiring more than a 15 percent stake in a domestic renewable energy producer in Nation X was subject to mandatory federal antitrust review unless the acquiring entity was a state-backed entity. In 2022, Nation X amended its regulations such that all corporate acquisitions of domestic energy producers, regardless of the acquiring entity's state-backed status or stake size, require mandatory federal antitrust review if the target firm holds exclusive regional distribution rights. Last year, Solis Corp, a private non-state-backed corporation, acquired a 12 percent stake in Terra Energy, a domestic renewable energy producer in Nation X, without undergoing a federal antitrust review.

Which of the following statements must be true based on the information provided above? Select all that apply.

A marine biology survey cataloged deep-sea coral reefs off the coast of Peninsula Y. The survey established that every reef located below a depth of 500 meters contains bioluminescent coral species. Furthermore, all coral reefs containing bioluminescent species in this region also host distinct populations of deep-sea shrimp. However, during the survey, several reefs located above a depth of 500 meters were found to host these same deep-sea shrimp populations.

Based on the survey results described above, which of the following statements must be true? (Select all that apply.)

Between 2018 and 2024, all commercial solar farms in Country X that integrated lithium-iron-phosphate (LFP) battery storage systems achieved continuous grid synchronization during peak demand hours. Conversely, no solar farm relying exclusively on nickel-manganese-cobalt (NMC) storage maintained uninterrupted grid connectivity throughout those same peak periods. During this six-year period, any solar farm in Country X that failed to maintain continuous grid synchronization during peak demand hours was assessed a regulatory surcharge. Furthermore, every commercial solar farm built in Country X after 2020 integrated either LFP or NMC storage systems, but never both.

Based on the information provided, which of the following statements must be logically true? Select all that apply.

Tab 1: Engineering Telemetry Summary
During Quarter 3, the facility's grid-scale battery energy storage system logged a roundtrip charge-discharge efficiency of $94\%$. Telemetry sensors recorded energy input and output strictly across the battery cell terminals during active storage cycles.

Tab 2: Financial Utility Billing Report
Energy billing records for Quarter 3 indicate that total kilowatt-hours ($\text{kWh}$) purchased from the regional utility grid exceeded baseline operating projections by $25\%$. Financial auditors concluded that net facility energy losses were far higher than the $6\%$ loss implied by battery telemetry.

Tab 3: Operations Maintenance Log
All auxiliary HVAC cooling units and thermal control systems operate on dedicated grid sub-circuits that bypass battery cell meters. Operational policy mandates continuous thermal conditioning whenever ambient site temperatures exceed $30^\circ\text{C}$. During Quarter 3, site temperatures exceeded $30^\circ\text{C}$ for $65\%$ of operational hours.

Based on the information provided across the three tabs, which of the following statements, if true, help resolve the apparent discrepancy between the $94\%$ battery efficiency reported in Tab 1 and the $25\%$ excess energy consumption reported in Tab 2? Select all that apply.

Tab 1: Supply Chain Audit Memorandum (Q1 2026)
The quarterly audit report concludes that Supplier Alpha achieved a $0\%$ defect rate for all $10{}000$ units of Component X received during Q1 2026. The audit's conclusion relies strictly on receiving-stage inspection records confirming that $100\%$ of delivered batches were logged as defect-free upon arrival.

Tab 2: Quality Control Standard Operating Procedure
Standard receiving protocol requires all precision electronic parts to undergo Quality Check 1 (QC-1) for visual/physical integrity and Quality Check 2 (QC-2) for thermal stress resistance before entry into inventory. However, components procured under "Express Procurement" status bypass QC-2 at receiving and are immediately marked as "Cleared at Entry." For Express Procurement items, thermal stress defects are recorded later during final post-assembly stress testing.

Tab 3: Plant Operations Defect Log (Q1 2026)
All $10{}000$ units of Component X supplied by Supplier Alpha in Q1 2026 were procured under Express Procurement contracts. During final post-assembly stress testing of finished products, $400$ units of Component X suffered thermal breakdown and failed inspection.

Based on the information provided across the three tabs, which of the following statements help reconcile the apparent contradiction between the receiving audit's $0\%$ defect rate in Tab 1 and the $400$ thermal failures reported in Tab 3? Select all that apply.
