Ram was asked to repeat after the speaker. Speaker: Red, Ram: Red. Speaker: Blue, Ram: Blue. Speaker: Green, Ram: Green. Speaker: What's your name? , Ram: Ram

What went wrong here?

Haha, that's a nice one. While Ram was asked to repeat after the speaker, he ended up taking the speaker's last phrase as a question and tried answering it, which isn't what he was instructed to do.
Ram should have repeated the last phrase, which would be as follows:
Speaker: What's your name? , Ram: What's your name?
