Compact discs (CDs) offer an improvement in artistic freedom over vinyl records. As the record needle moves in toward a vinyl record' s center, it must fight centrifugal force. Wide, shallow, or jagged grooves will cause the needle to jump; consequently, the song nearest the center -- the last song on the side -- cannot have especially loud, high-pitched, or low-pitched passages. The CD suffers no such limitations, leaving artists free to end recordings with any song. Which one of the following most accurately expresses the main conclusion of the argument? ['On vinyl records, the song farthest from the center can have loud, high-pitched, or low-pitched passages.', "As the record needle moves in toward the vinyl record's center, the centrifugal force on the needle becomes stronger.", 'CDs can have louder passages, as well as both higher- and lower-pitched passages, than can vinyl records.', 'CDs provide greater artistic latitude than do vinyl records.']
