What inference can be drawn if a product description states: "Manufactured using 100% post-consumer recycled aluminum, reducing energy consumption by 95% compared to raw ore extraction."?
Answer and explanation
Correct answer: A. Recycling aluminum saves significant energy compared to primary smelting
- Step 1: Read the explicit factual claim: using post-consumer recycled aluminum reduces energy consumption by compared to raw ore extraction.
- Step 2: Determine the logical deduction from this data: extracting and smelting virgin aluminum from raw bauxite ore requires vastly more energy than remelting post-consumer recycled aluminum.
- Step 3: A reduction constitutes substantial energy savings, directly validating that recycling aluminum saves significant energy compared to primary smelting.
Answer
Recycling aluminum saves significant energy compared to primary smelting.
