Sentence Correction

Identify the error:

since the start of the millennium provides

This question is about subject-verb agreement. The subject
"ubiquity" and the verb "provides" are both singular, so the pair matches in number. However, a subject-verb pair must also be logical. It is the personal music player, not the ubiquity, that "provides users with a distraction on long commutes and can now
hold thousands of songs."
