Finish your work otherwise you will not be sent home

Answer 2

Finish your work otherwise, you will not be sent home.

Detailed answer

This is the completed sentence of the above question.

• The sentence now conveys that the person would not be sent home if he does not finish his work.
• The word otherwise is the most grammatically appropriate word to be used at a particular moment.
• For any other word for example if we had used the word "then" it would have made a sentence that doesn't mean anything or is grammatically incorrect.
