Difficulty: EasyCompleting the Passage Logically

Which phrase logically completes the passage below?

Answer:A commercial bakery recently replaced its gas-powered ovens with high-efficiency electric ovens that consume 30 percent less energy per batch of goods. Although electricity costs more per unit of energy than natural gas does in this region, the bakery's total monthly expenditure on oven energy decreased immediately after the replacement. Assuming energy prices and production volume remained constant, this financial outcome indicates that 【the reduction in energy consumption was large enough to offset the higher unit cost of electricity】.

Answer

the reduction in energy consumption was large enough to offset the higher unit cost of electricity
Total energy spending is determined by multiplying total energy consumed by the price per unit of energy. The passage states that the per-unit price of electricity is higher than that of gas, yet overall spending decreased. The only logical explanation for total spending falling under a higher unit rate is that the 30 percent reduction in energy consumption was large enough to outweigh the higher unit cost of electricity.

Step-by-Step Solution

1
Identify the given premises in the passage
1. Electric ovens use 30% less energy per batch than gas ovens.
2. Electricity costs more per unit of energy than natural gas.
3. Total monthly energy spending decreased after switching to electric ovens.
Understanding the factual foundation of the argument is required before completing the logical bridge.
2
Analyze the relationship between unit cost, usage volume, and total expenditure
Total Expenditure = (Energy Consumed) × (Cost Per Unit of Energy).
Since the cost per unit increased, total expenditure could only decrease if the decrease in energy consumed was substantial enough to outweigh the price increase.
3
Formulate the logical completion
The lower volume of energy consumed was sufficient to overcome the higher per-unit rate of electricity.
This directly explains how total spending fell despite paying a higher unit price.
