Answer :
"Before the game started the team, warmed up to energizing music." is the one with the error.
The comma should be after "started", not after "team"
It should be "Before the game started, the team warmed up to energizing music."
The comma should be after "started", not after "team"
It should be "Before the game started, the team warmed up to energizing music."
The comma error is in the sentence: "Before the game started the team, warmed up to energizing music."
