How does Carnegie demonstrate the safety of the bridge to the public?

• A. He performs a series of strength tests
• B. He has a famous architect endorse it
• C. He has an elephant cross it to dispel superstition
• D. He builds a second bridge for comparison

Answer: (C)

Carnegie demonstrates the safety of the bridge to the public through the dramatic approach of having an elephant cross it. This spectacle was intended not only to showcase the bridge’s strength and durability but also to dispel superstitions surrounding its safety. The use of an elephant, a heavy and formidable animal, served to provide a clear visual representation of the bridge's capability to withstand significant weight, addressing public concerns and fears directly. The public's perception of bridge safety at the time was influenced by various cultural beliefs, and this bold demonstration was a unique way to reassure onlookers that the structure was sound.

Other options, while they may also contribute to establishing credibility, do not capture the same level of dramatic impact and public engagement as the elephant crossing does. Strength tests or endorsements by a famous architect might confirm safety in a traditional sense, but they lack the visual spectacle that would resonate with the public mindset of that era.
