Question

Почему никто из присутствующих гостей Троекурова не узнал Дубровского?

Answer 1

Потому что когда присутствовали гости на Дубровского никто не обратил внимания так как Дубровский играл в роли француза-
учителя Дефоржа. Дефорж учил Сашу говорить на французком и никто не знал, что Дефорж знает русский язык.
