What could the phonograph do?

Question

BlackTom AI · Accepted Answer

Examining what the phonograph could do requires matching historical function with the given options.
Option 1: 'Only play back sound' — This is incomplete. The phonograph was designed not only to play back prerecorded sound but also to record it, so this option fails to capture the full capability.
Option 2: 'Only record sound' — Also incomplete. While recording was part of the phonograph's capability, the device was primarily used to store and later replay the recorded sound, so limiting it to only recording omits the playback function.
Option 3: 'Record and play back sound' — This is the historically accurate description. The phonograph was capable of both recording sound onto a medium and playing it back, enabling listening to the recorded material again.
Option 4: 'Visually study sound' — This mischaracterizes the device. A phonograph records and reproduces audio; it does not visually study sound, and the term 'visually study' does not reflect its primary function of audio recording and playback.

In summary, to capture the essential function of the phonograph, the option that states it could record and play back sound aligns with its intended use and historical purpose, whereas the other choices omit or misstate key capabilities.
