what type of error is present in the underlined sente
whic
comma splice
fragment
run - on

Explanation:

A run - on sentence occurs when two or more independent clauses are joined without proper punctuation or conjunctions. In the sentence “Many people play a musical instrument music can be soothing”, the two independent clauses “Many people play a musical instrument” and “music can be soothing” are stuck together without a comma, conjunction, or other appropriate punctuation. A comma splice uses a comma to join two independent clauses (which is not the case here as there's no comma), and a fragment is an incomplete sentence (this is a complete - thought - related error, not a fragment). So the error is a run - on.

Answer:

run - on
