1.都正确。但是语言课是指母语在内的各种语言课。外语课指除了母语以外的语言课。 2.正确

For the 1st question, I think the scope of the first one contains the 2nd one. The 2nd one is more specific. 语言 contains your mother language and foreign languages. For the 2nd question, it is not a completed sentence, just like the expression "My Iranian name" which without any other part. Do you think "My Iranian name" is a correct sentence?
