Answer:
The team lost the game because the players made mistakes
Step-by-step explanation:
When a sentence is in active voice, it means that the subject of the sentence acts upon its verb. That is, the subject is carrying out the action in the sentence.
Hence, in the active voice, the subject of a sentence performs the action portrayed in the sentence.
If the sentence is 'The coach said the team lost by making many mistakes'. The active voice must directly connect the action of the players to the loss of the team. Hence the active voice is; 'The team lost the game because the players made mistakes'.
