Which individual is known for being able to transcribe Morse code by ear?

• A. John D. Rockefeller
• B. Andrew Carnegie
• C. J.P. Morgan
• D. Henry Ford

Answer: (B)

The correct answer is Andrew Carnegie. He is recognized not only for his immense wealth and influence in the steel industry but also for his early experience with Morse code. Carnegie worked as a telegraph operator in his youth, and during this time, he developed the skill of transcribing Morse code by ear. This competency was instrumental in helping him build connections and advance his career in the burgeoning industrial landscape of the United States.

The other individuals listed, while significant figures in American industry, are not specifically known for their ability to transcribe Morse code. John D. Rockefeller was primarily focused on the oil industry; J.P. Morgan is known for his banking and finance prowess; and Henry Ford revolutionized automobile manufacturing through practices like assembly line production, none of which include notable skills in Morse code transcription.
