When an ablative absolute has a present participle its action happens at the same time as the main clause?

Answer 1

This is true. In Latin the present happens at the same time as the main clause.

Answer 2

Yes, when an ablative absolute has a present participle, it indicates that the action of the participle is happening simultaneously with the main action of the sentence. This construction is commonly used in Latin to provide additional context or background information to the main clause.
