Answer 1

We must maintain discipline otherwise teacher will punish us.

Answer 2

If we don't maintain silence, the teacher will punish us.

• We have to change the given compound sentence into a complex sentence.
• A complex sentence has two clauses, the main and the subordinate clause.
• Conjunctions like if, because, as, since, otherwise, etc are used to connect the main and subordinate clauses.
• Here, we will use it to change it into a complex sentence.

So the answer is,' If we don't maintain silence, the teacher will punish us.'
