Помогите пожалуйста… Нужно выбрать одно из двух, что разделяется знаком "/". Заранееспасибо! My school, was an old established Grammar School founded (1) in/ at the 16 th century. The school was very proud (2) by / of its history and traditions. There was also pride in the idea that just because it (3) were/ was an old school it was a good school, certainly a beller school (4) then /than others in nearby towns and other suburbs of London. This idea was certainly supported (5) by/with a lot of the parents, who, to a large extent, were what would be called middle class. It was this pride that created the (6) code / way of dress. What we (7) have / had to wear was, looking back, rather strange.
