Question

select from the drop-down menus the correct punctuation.

terrence likes listening to music while studying choose... however choose... the music sometimes distracts him.

Explanation:

1. The first blank comes at the end of an independent clause ("Terrence likes listening to music while studying") before the conjunctive adverb "however". A semicolon is required here to connect two related independent clauses with a conjunctive adverb.
2. The second blank follows the conjunctive adverb "however" at the start of the second independent clause ("the music sometimes distracts him"). A comma must follow a conjunctive adverb when it begins a clause.

Answer:

First drop-down: ; (semicolon)
Second drop-down: , (comma)

Full corrected sentence: Terrence likes listening to music while studying; however, the music sometimes distracts him.
