How could the sentence below be improved?
i thought his song was great, even though i don't usually like country music.
replace the word great with a more specific word
identify the speaker in the sentence
replace the comma after great with a semicolon
none of the above

The answer to your question is none of the above.

Explanation:

"Even though" is a subordinating conjunction. Subordinating conjunctions create complex sentences: Sentences that have two clauses, one independent and one dependent. The conjunction creates a proper transition between the ideas and semantic relationships between them (cause and effect, contrast, time, place).  There should never be a comma between an independent clause and a dependent one. Nevertheless, if the subordinate clause comes before the complete sentence, you should use a comma after it (see a and b).

a) Even though I don't usually like country music, I thought his song was great

b) * Even though I don't usually like country music I thought his song was great

the antonym of esurient is abstemious.
