Difficulty: MediumMulti-Statement Boolean Evaluation

The table below presents 2025 operational performance and cost metrics for eight regional commercial biofuel production facilities:

Facility NameFeedstock TypeAnnual Output (Million L)Operating Cost ($/L)Carbon Intensity Reduction (%)Capacity Utilization Rate (%)
BioAlphaCellulosic850.7268%88%
EcoEthanolCorn Stover1200.5545%92%

Vanguard BioAlgae600.9885%80%
SunFuel NorthCorn Stover1500.5042%90%
NextGen FuelUsed Cooking Oil750.7670%85%

Based on the data provided, evaluate whether the following overall assertion is True or False:

"Exactly two of the three statements below are True:
- Statement 1: The median Annual Output among facilities with a Carbon Intensity Reduction of at least 70% is 67.5 Million Liters.
- Statement 2: For all facilities utilizing Cellulosic or Algae feedstock, the Operating Cost per Liter is strictly greater than $0.65.
- Statement 3: The facility with the highest Capacity Utilization Rate incurred a lower total annual operating cost (calculated as Annual Output × Operating Cost) than the facility with the lowest Capacity Utilization Rate."

Answer: Answer

Answer

True. Statements 1 and 2 are True, while Statement 3 is False, meaning exactly two of the three statements are True.
Evaluating the individual statements reveals that Statement 1 is True (the median of {40, 60, 75, 95} is 67.5), Statement 2 is True (operating costs for Cellulosic and Algae facilities are 0.72,0.72, 1.10, 0.68,and0.68, and 0.98, all greater than 0.65),andStatement3isFalse(PureBiostotalcostof0.65), and Statement 3 is False (PureBio's total cost of 60.8 Million exceeds GreenFuel X's total cost of $44.0 Million). Since exactly two statements are True, the overall compound assertion is True.

Step-by-Step Solution

1
Evaluate Statement 1: Identify facilities with Carbon Intensity Reduction ≥ 70% and calculate their median Annual Output.
Facilities satisfying the condition are GreenFuel X (82%), PureBio (74%), Vanguard Bio (85%), and NextGen Fuel (70%). Their outputs are 40, 95, 60, and 75 Million Liters, respectively. Ordering these values: 40, 60, 75, 95. The median of an even set of four numbers is (60+75)/2=67.5(60 + 75) / 2 = 67.5 Million Liters. Thus, Statement 1 is True.
Correctly filtering by the conditional threshold (70%) and sorting the output values is required to calculate the median of an even dataset.
2
Evaluate Statement 2: Filter for facilities using Cellulosic or Algae feedstock and compare their Operating Costs to $0.65.
Facilities matching Cellulosic or Algae feedstock are BioAlpha (0.72),GreenFuelX(0.72), GreenFuel X ( 1.10), TerraFuel (0.68),andVanguardBio(0.68), and Vanguard Bio ( 0.98). Every single one of these operating costs is strictly greater than $0.65. Thus, Statement 2 is True.
A universal condition ('for all') requires checking every matching row to ensure no counterexample exists.
3
Evaluate Statement 3: Identify facilities with the highest and lowest Capacity Utilization Rates, compute their total annual operating costs, and compare.
Highest Capacity Utilization Rate: PureBio (95%). Total annual operating cost = 95 Million L×$0.64/L=$60.8 Million95 \text{ Million L} \times \$0.64/\text{L} = \$60.8 \text{ Million}. Lowest Capacity Utilization Rate: GreenFuel X (75%). Total annual operating cost = 40 Million L×$1.10/L=$44.0 Million40 \text{ Million L} \times \$1.10/\text{L} = \$44.0 \text{ Million}. Since $60.8 Million>$44.0 Million\$60.8 \text{ Million} > \$44.0 \text{ Million}, the highest utilization facility did NOT incur a lower cost. Thus, Statement 3 is False.
Row-level product calculations must be performed accurately for both extreme values before evaluating the inequality.
4
Synthesize the truth values of the three statements to evaluate the overall assertion.
Statement 1 = True, Statement 2 = True, Statement 3 = False. Total number of True statements = 2. Therefore, the assertion 'Exactly two of the three statements below are True' is True.
The top-level boolean logic requires assessing whether the count of True individual statements equals 2.
