Question

fix any punctuation or capitalization errors below. click \submit answer\ if there are none.
shrek planned to surprise all his classmates by hiding chocolate bars in their desks; his teacher, however, ate most of them before school.

Explanation:

The original error is a misplaced comma: "however, ate" incorrectly splits the subject ("his teacher") and verb ("ate"). Moving the comma to set off the parenthetical "however" correctly (placing it after "however") fixes the issue, as parenthetical adverbs in the middle of a clause need commas on both sides. The semicolon between the two independent clauses is already used correctly to connect related complete thoughts.
