The following paragraphs are from an essay about audio preservation.
[1]
In the late nineteenth century, Thomas Edison's phonograph introduced the world to recorded sound using wax cylinders. Although these cylinders represented a monumental leap in technology, they were extremely fragile. Made of a soft metallic wax compound, the cylinders degraded slightly with each playback, and they were highly susceptible to mold growth and physical wear. As a result, early recordings of historical speeches and musical performances were gradually lost to time.

______[1]______ Using high-resolution digital cameras, the system takes microscopic images of the grooves on a cylinder's surface. Software then analyzes these visual representations to reconstruct the audio digitally, allowing researchers to play back the audio without ever touching the fragile wax. This technology has successfully rescued thousands of historic voices from silence, ensuring that these fragile records are preserved for future generations.
Which choice provides the most effective transition from the preceding paragraph to the rest of the passage?
- To salvage these fading voices, modern sound archivists have turned to digital imaging technologies.Answer
- BSound archivists wanted to protect the cylinders, they shifted their focus to digital imaging techniques.
- CWax cylinders are very fragile and degrade easily when played back, which is why archivists want to save them.
- DTo salvage these fading voices, modern sound archivists turned to digital imaging technologies that will have scanned the wax.
