1. B) given
2. A) take. This one is a bit tricky, because if only "taked" was underlined, the correct version would be 'taken'. But if "have taked" is underlined, 'take' would work the same as 'have taken'.
What are the choices? If I had to choose a phrase without knowing of any choices, I would put "Bad studying" But im pretty sure thats not the answer you are looking for.
Yes I think it does. To be safe I think you should research it.
Question #1 : Letter A.
Question #2 : Letter B.
Question #3 : Letter A.
Question #4 : I'm not really sure, but I think the best answer would be Letter C.
I hope this helps you !
