In 2010, engineer Elena Rossi was working on digitizing damaged historical audio recordings. She found that some audio segments were so full of static that speech-to-text software could not transcribe them, yet the human ear could still decipher the words. Based on this, Rossi created a verification system to block automated "bots" from websites. The system asked users to type out the words heard in a static-filled audio clip. Correct answers verified the user was human and simultaneously helped transcribe the historical audio archives.
Which choice best states the main purpose of the text?
To explain the commercial failure of Rossi's audio project
To discuss the invention and dual purpose of Rossi’s verification system
To argue that automated software is better than human hearing
To describe how static is removed from old recordings
Correct Answer: B
Choice B is the best answer. The text describes a problem (static in recordings) and explains how Rossi invented a system to solve it while verifying human users. This covers the invention and its dual purpose.
Choice A is incorrect. The project was successful (added data), not a failure. Choice C is incorrect. The text explains a specific system, not a general argument about AI vs. humans. Choice D is incorrect. It explains transcription, not static removal technology.
