Answer 2

The situation that is an example of human error is an eyewitness account of the Challenger explosion.(Option C)

• Human error refers to mistakes or failures that are made by people rather than by mechanical or technological factors.
• In the case of the Challenger explosion, human error was a contributing factor. The spacecraft exploded shortly after launch due to a faulty seal on one of the solid rocket boosters, which was caused by a combination of design flaws and human error.
• One of the contributing factors to the Challenger disaster was the failure of engineers to communicate their concerns about the O-ring seals to management, which resulted in a flawed decision to launch the spacecraft.
• The eyewitness account of the Challenger explosion refers to the perception and interpretation of the event by an individual who was present at the time. While this may provide valuable information about the event, it is subject to the limitations and biases of human perception and memory.
• In contrast, the discovery of penicillin, the disappearance of the Aral Sea, and the DNA analysis of King Tutankhamen's bones are not examples of human error as they are not directly related to mistakes or failures made by people.
• The discovery of penicillin was a scientific breakthrough that resulted from the careful observation and experimentation of Alexander Fleming.
• The disappearance of the Aral Sea was caused by a combination of environmental factors such as climate change and human activities such as irrigation and damming of rivers.
• The DNA analysis of King Tutankhamen's bones was a scientific investigation that used state-of-the-art techniques to uncover new information about the ancient Egyptian pharaoh.
