Question

Найдите ошибку: 1) students haven't to wear a uniform in our school and so you can wear what you want 2) you mustn't drink and drive- it's illegal

Answer 1

1) "to" лишнее
2)после it's должна быть частица not (без нее данное предложение бесмыслено )

Answer 2

1. The error in the sentence is the use of "haven't to wear" instead of "don't have to wear." The correct sentence would be: "Students don't have to wear a uniform in our school, so you can wear what you want."

2. There is no grammatical error in the sentence. It correctly states that you must not drink and drive because it is illegal.
