In America, I find actors who have learned to speak RP(Received Pronunciation), or Standard English, but sound unnatural, I investigate their voice training and the horror stories emerge: \'i was told my accent was lower class and that, from now on, I was only to speak RP.\' This is an instance of RP being ________.

1. the most effective way of speaking

2. the only acceptable pronunciation in the English speaking countries.

3. merely one of many English pronunciations

4. embraced for all the wrong reasons
