Honestly, I hate to say it but this is slightly lazy you could read this easily and get a perfect score by yourself. Regardless I will help you, but please try and do it yourself even if you answer one question. I'm sure your smarter than this. Anyways here is the multiple choice:
1.A
2.D
3.B
4.C
Long response: His motivations for learning guitar was when he listened to blues and heard Mr.Collin's music. As stated in the first paragraph, he was interested so he worked hard to do what he loved.
The adjective clause is " that his dad gave him "
it is describing the knife.....which knife ? the one that his dad gave him
I don't know which one you are referring to but if he got so excited about what he seen on his exam he probably jumped up and down in excitement.
Hope this helped, have a great day! :D
