Questions: Which statement is a scientific conclusion? A. Silver is not widely used to conduct electricity because it is expensive. B. Silver wires conduct electricity better than copper wires. C. Silver rings are prettier than copper rings because silver is shinier. D. Will silver wires conduct electricity better than copper wires?

Solution Steps

The question asks us to identify which statement is a scientific conclusion. A scientific conclusion is typically a statement that is based on empirical evidence and can be tested or observed.

• Option A: "Silver is not widely used to conduct electricity because it is expensive." This is more of an economic or practical consideration rather than a scientific conclusion.
• Option B: "Silver wires conduct electricity better than copper wires." This is a statement that can be tested and is based on the physical properties of silver and copper, making it a scientific conclusion.
• Option C: "Silver rings are prettier than copper rings because silver is shinier." This is a subjective statement based on personal preference, not a scientific conclusion.
• Option D: "Will silver wires conduct electricity better than copper wires?" This is a question, not a conclusion.

Based on the analysis, Option B is the statement that qualifies as a scientific conclusion because it is based on measurable and testable properties of materials.
