6 Parts of the following sentence have been given as options. Select the option that contains an error.
In some countries, you are not able to drink until you are 21.

Question

Accepted Answer

The error lies in the phrase 'until you are 21.' The correct expression should be 'until you are 21 years old' or 'until you turn 21.' The phrase 'until you are 21' is incomplete and informal. The other parts of the sentence are grammatically correct.
